139. Using 'substring( )' method

substring( ) method is used to extract a portion from the actual string using the following two formats:

• "StringText".substring(startIndex) -> Example: "SunShine".substring(3) -> It will extract the portion of string starting from Index 3 to the end of the string 
• "StringText".substring(startIndex, endIndex) -> Example: "SuperSunShine".substring(5,8) -> It will extract the portion of string starting from Index 5 to the Index (8-1)

Lets implement this on Eclipse IDE:

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

2. Save and Run the 'substringDemo' class file

3. Observe that the output is displayed in the console as shown below:
