1. What is the difference between Implicit Wait and Explicit Wait ?
Answer: Explicit Wait will make the WebDriver wait for a specific web element for the specified time. i.e. Using Explicit Wait, we can make the WebDriver wait for web element 'a' for 5 seconds and another web element 'b' for 10 seconds.
Where as Implicit Wait will make the WebDriver wait for all web elements for the same specified time. Its generally not set for one or two web elements, instead it is once set will be applicable for all elements. i.e. Unlike Explicit Wait, Implicit Wait once set will be applicable to all the web elements and hence the specified wait time will be applicable for all the web elements.
2. What are the different Classes which implement WebDriver ?
Answer: First of all WebDriver is an Interface and there are different classes which implement this Interface in Selenium. The Classes which implement the WebDriver interface in Selenium are FirefoxDriver, ChromeDriver, InternetExplorerDriver, OperaDriver, SafariDriver, RemoteWebDriver, EdgeDriver and EventFiringWebDriver Classes.
Example: In the statement WebDriver driver = new FirefoxDriver(); , WebDriver is an Interface and FirefoxDriver is one of the Classes which is implementing WebDriver Interface.
3. How to read tool tip text using Selenium WebDriver ?
Answer: Tool Tip is a text that will be displayed when we hover our mouse cursor over the text or web element on any web page. Selenium WebDriver can read the tool tip text using getAttribute() method. Click here to read how Selenium WebDriver uses getAttribute() method for reading a tool tip from a web page.
4. What are the different WebDriver exceptions, you have faced while working with Selenium Projects ?
Answer: Exception is a problem which occurs during the execution of the program and there by stops the program from further execution. Similarly, while running the Selenium programs, different types of Exceptions related to WebDriver may arise. The list of WebDriver related Exceptions that may commonly arise during Selenium programs execution are: NoSuchElementException, ElementNotVisibleException, NoSuchFrameException, NoAlertPresentException, NoSuchWindowException, SessionNotFoundException and StaleElementReferenceException. Click here to find out more on these WebDriver exceptions.
5. Can Selenium automate Desktop Applications ?
Answer: No. Selenium can only automate Web Applications.
Examples: Web Applications like Facebook.com, Gmail.com etc can be automated by Selenium. Where as the Desktop Applications like Paint, Skype, MS Office etc. cannot be automated by Selenium.
6. What are the different components / tools in Selenium ?
Answer: Selenium comprises of 4 different components / tools. i.e. Selenium IDE, Selenium RC, Selenium WebDriver and Selenium Grid.
7. What is the latest version of Selenium ?
Selenium got released into the market in three different versions so far and hence Selenium 3 is the latest version.
8. What is the purpose of using Firebug ?
Answer: Firebug is a firefox add-on which helps us in locating HTML code for the inspected GUI elements on the web pages.
9. What is Selenium IDE ?
Answer: Selenium is one of the components / tools of Selenium and is a Record & Playback tool.
10. What is the main component of Selenium ?
Answer: Selenium WebDriver is the main component of Selenium.
Selenium is one of the components / tools of Selenium and is a Record & Playback tool.
11. What is the disadvantage of using Selenium IDE ?
Answer: Its not suitable for automating the complex applications, as the maintenance of automated tests is more. i.e. If any functionality changes on the application, the automation engineer has to re-record all the automated tests which got affected with this change again in Selenium IDE
12. What are the different types of Locators ?
Answer: id, name, class name, link text, css selectors , xpath expressions and DOM are the different types of locators which we use in Selenium for locating the GUI elements on the web pages.
13. What is the priority in which we have to use the locators ?
Answer: We have to use the locators in the below specified priority:
- First Priority : id locator
- Second Priority : name locator
- Third Priority: Class Name locator
- Fourth Priority: link text locator
- Fifth Priority: CSS Selectors locator
- Sixth Priority: XPath locator
- Seventh Priority: DOM locator
14. What is the difference between Absolute XPath and Relative XPath Expressions ?
Answer: Complete path has to be specified with Absolute XPath expressions, where as in Relative XPath Expressions we can provide direct path to the UI elements.
Hence because of simple changes in the applications functionality, the complete path in absolute XPath may change. Since Relative XPath is the direct path, its path won't change with the simple changes in the application.
15. What is the disadvantage of Absolute XPath and why is Relative XPath recommended over it ?
Answer: For simple changes on the application like moving the button from one place on the page to other place, the absolute XPath expression changes. As Relative XPath expressions won't change with these simple UI changes on the pages, hence Relative XPath is recommended over Absolute XPath.
16. What is the concept that makes XPath Expressions powerful out of all the locators ?
Answer: XPath AXES is the concept which makes the XPath Expressions powerful out of all the locators. i.e. By using XPath AXES we can traverse both forward and backwards in the HTML code of the web pages.
17. Why CSS Selectors have higher priority over XPath Expressions ?
Answer: The below are two reasons why CSS Selectors are preferred over XPath Expressions:
- When compared to XPath Expressions, CSS Selectors locate the UI elements faster.
- Selenium may not be able to locate few UI elements using XPath Expressions, while executing the Automation scripts on Internet Explorer Browser.
18. What is the name of the Add-on which can automatically generate the XPath Expressions and CSS Selectors ?
Answer: Firepath is the Add-on which can auto generate the XPath Expressions and CSS Selectors, just by inspecting the GUI elements on the web pages.
19. Write a Java Program to print the even numbers between 1 and 100 using for loop ?
Answer: The below for loop can print the even numbers between 1 to 100:
for(int i=1;i<=100;i++) {
if(i%2==0) {
System.out.println(i);
}
}
20. Write a Java Program to find the sum of first 100 numbers using for loop ?
Answer: The below for loop can find the sum of first 100 numbers:
int sum = 0;
for(int i=1;i<=100;i++) {
sum = sum + i;
}
System.out.println("The sum of first 100 numbers is : "+sum);
21. Write a for loop which prints numbers from 1 to 100. But if the number is divisible by 5, then it should print 'divisible by 5 followed by that number' ?
Answer: The below for loop solves the below question:
for(int i=1;i<=100;i++) {
if(i%5==0) {
System.out.println("Divisible by 5 : "+i);
}else {
System.out.println(i);
}
}
22. Does Java support multiple inheritance ?
Answer: The answer is No and Yes. i.e. No in case of Classes and Yes in case of Interfaces.
Multiple inheritance is not supported in case of Classes:
In case of Classes, a single class cannot inherit multiple classes due to the ambiguity problem.
Lets say there are three Classes i.e. ClassA, ClassB and ClassC. Assume that ClassA and ClassB have a method having same name say mOne() . In this case, if ClassC extends both ClassA and ClassC, then there is an ambiguity of inheriting mOne() from either ClassA or ClassB. i.e. Java cannot decide whether the mOne() can be inherited from ClassA or ClassB.
Hence multiple inheritance is not supported for Classes in Java.
Multiple inheritance is supported in case of Interfaces:
In case of Interfaces, a single class can inherit multiple interfaces as there is no ambiguity problem.
Lets say there are two interfaces i.e. InterfaceA, InterfaceB and a class ClassC. Though InterfaceA and InterfaceB have a method with same name say mOne(), ClassC can still inherit multiple interfaces, as mOne() method is not implemented in any of the interfaces.
Hence multiple inheritance is supported by Interfaces in Java.
23. What is the parent or base class of all the classes in Java ?
Answer: All the classes in Java are children or grand children of Object Class.
24. What is the difference between instance variables and local variables in Java ?
Answer: Variables declared inside the methods are known as local variables, where as the variables which are declared directly inside the class but outside the methods are known as Instance variables.
Answer: Variables declared inside the methods are known as local variables, where as the variables which are declared directly inside the class but outside the methods are known as Instance variables.
25. Is Java a pure or 100% Object Oriented Programming language ?
Answer: No. Java uses primitive data types, hence it is not a 100% or pure Object Oriented Programming language.
Answer: No. Java uses primitive data types, hence it is not a 100% or pure Object Oriented Programming language.
26. What is the difference between Primitive and Non-Primitive Data types in Java ?
Answer: Predefined or default data types in Java are known as Primitive Data types.
Examples for Primitive Data types are : byte, short, int, long, float, double, char and boolean
Programmer defined data types in Java are known as Non-Primitive Data types. objects can be created for non-primitive data types.
Examples for Non-Primitive Data types are : Strings, Arrays and Classes.
Answer: Predefined or default data types in Java are known as Primitive Data types.
Examples for Primitive Data types are : byte, short, int, long, float, double, char and boolean
Programmer defined data types in Java are known as Non-Primitive Data types. objects can be created for non-primitive data types.
Examples for Non-Primitive Data types are : Strings, Arrays and Classes.
27. Why Strings are immutable in Java ?
Answer: In Java Strings are by default immutable (i.e. once created they cannot be changed).
For example: If you assign a value to the String say "Arun Motoori" as shown below:
String name = "Arun Motoori";
And, in the next statement, I will change the value of the String to other value say "Arun Kumar" as shown below:
name = "Arun Kumar";
After performing the above two steps, though it looks like the value has been updated. But in real a new object will be created to store new value "Arun Kumar" and the old object storing "Arun Motoori" is not deleted. i.e. Instead of updating or changing the value stored in old object, a new object will be created for every new value assigned to the same variable of String.
So in Strings, on assigning a value to the variable, a new object will be created to store the value and the value stored in the object cannot be changed or mutated. Hence Strings are immutable in Java.
But, StringBuffer in Java are mutable or changeable.
28. What is the difference between String and StringBuffer classes in Java ?
Answer: Strings in Java are immutable (i.e. cannot be changed once created), where as StringBuffer is mutable.
Note: Refer to the Question 27 fore more details.
29. Write a program for accessing all the elements of the below two Dimensional array using for loop.
int[][] a = {{5,2,9},{4,6,8}};
Answer: The below program accesses all the elements of a two dimensional array using for loop:
for(int i=0;i<a.length;i++) {
for(int j=0;j<a[i].length;j++) {

}
System.out.println();
}
30. How to assign different types of values say integer, character, String, decimal and boolean into the same array ?
Answer: By creating the arrays as Object Class type, we can assign different types of values say integer, character, String, decimal and boolean into the same array.
31. What is the disadvantage of Arrays ?
Answer: Arrays are fixed in size. i.e. After creating an Arrays, we cannot change its size at later point of the program.
32. Practical Assignment : Go to Java 8 API page over Web and find the String predefined class and its predefined methods say equals(), substring(), length(), trim() etc. .

34. What is the purpose of using Wrapper classes in Java ?
Answer: Wrapper classes represent respective data types values as objects in Java.
Example: 'Integer' wrapper class represents 'int' data type value as an object in J.
35. What is the purpose of using Constructors in Java ?
Answer: Constructors simplify the initialization of variables in Java.
Reason: Instead of initializing the variables for each and every object, we can create a constructor to initialize these variables, as the constructor is automatically called when the object is created.
36. How constructors are different from methods in Java ?
Answer: The below are few differences between constructors and methods in Java:
- Constructors must have the same name of their Class name
- Constructors are automatically called when the Objects are created for the Class
- Constructors won't have any return type
37. What is the purpose of using "this" keyword in Java ?
Answer: The purpose of using "this" keyword in Constructors and methods, is to differentiate the instance variables from the parameterized variables having same names.

Answer: In order to access the variables and methods from another class in Java, we have to create an Object for the Class having those variables and methods.
42. What is Overriding in Java ?
Answer: When a method in the Child class (i.e. sub-class) is duplicate of a method in Parent class (i.e. super-class) , then the method in the sub-class is said to override the method in super-class.
Answer: When a method in the Child class (i.e. sub-class) is duplicate of a method in Parent class (i.e. super-class) , then the method in the sub-class is said to override the method in super-class.
43. Is Overriding applicable for Constructors in Java ?
Answer: No, Overriding can be implemented only for methods and cannot be implemented for Constructors.
Reason: As the name of the constructors needs to be same as the name of the Classes, Overriding is not applicable for constructors.
44. What are different modifiers in Java ?
Answer: Modifiers in Java can be categorized into two types i.e. Access modifiers and Non-Access modifiers.
- Different Access modifiers we have in Java are - public, private, protected and default
- Different Non-Access modifiers we have in Java are - static, final and abstract
45. What is the difference between default and protected access modifiers in Java ?
Answer: Both default and protected access modifiers specified properties act as public to all the Classes inside the same package.
But coming to the Classes outside the package, default and protected properties act as private.
The difference between default and protected is that, protected specified properties can be inherited outside the package, where as default specified properties cannot be inherited outside the package.
46. What is the difference between static variables and instance variables in Java ?
Answer: static variables belong to the class memory, hence needs to be called using the Class name. Where as instance variables belong to the object memory, hence needs to be called using object reference.
Answer: static variables belong to the class memory, hence needs to be called using the Class name. Where as instance variables belong to the object memory, hence needs to be called using object reference.
47. What are the differences between static methods and non-static methods in Java ?
Answer: The below are the differences between static methods and non-static methods in Java:
- static methods belong to class memory, hence needs to be called using the Class name. Where as non-static methods belong to object memory, hence needs to be called using object reference.
- static methods can only access static variables and static methods. Where as non-static methods can access both static and non-static variables and methods.
48. What happens when we specify the final non-access modifier with variables and methods in Java ?

90. How can we create a Data Driven Framework using TestNG ?
Answer: TestNG provides an annotation known as @DataProvider and also dataProvider attriubute of @Test annotation. Using which, we will be able to achieve the Parametrization of tests. Hence the role of TestNG in Data Driven framework is to parameterize the tests using the above specified annotations and their attributes. Along with TestNG, we also need to use POI API for reading the test data from the Excel files.
