155. Using 'substring( )' method with StringBuffer

substring( ) method when used with StringBuffer extracts a portion from the provided string using the following two formats:

Example: (Format 1)

StringBuffer object1 = new StringBuffer("SunShine");
object1.substring(3);  -> This will extract the text in "SunShine" from index 3 till the end i.e. It will extract "Shine" in this example.

Example: (Format 2)


StringBuffer object2 = new StringBuffer("SuperSunShine");
object1.substring(5,8);  -> This will extract the text in "SuperSunShine" from index 3 till index (8-1) i.e. It will extract "Sun" in this example.

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:
