149. Using append( ) method with StringBuffer

append( ) method when used with StringBuffer concatenates the provided data to the end of the invoking StringBuffer object.

Example:

StringBuffer object1 = new StringBuffer("Start");
int num = 123;
String str = "abc";
StringBuffer object2 = new StringBuffer("Stop");

object1.append(num).append(456).append(str).append("xyz").append(object2);  -> This statement will append 123,456,abc,xyz and Stop to the "Start" text -> i.e. This will result Start123456abcxyzStop

Lets implement this on Eclipse IDE:

1. Create 'appendDemo' class under any project as shown below:

2. Save and Run the 'appendDemo' class file
3. Observe that the output is displayed in the console as shown below:
