In this section, you will learn how to work with StringBuffer and append data to it. The StringBuffer is a class that implements multiple sequence of characters. The following program construct a string buffer that has '0' capacity. This program inserts the data in the string buffer using the insert() method that provides the facility for adding the data in any positions. But the append() method also add data in string buffer in ending position. This method inserts always last or end position.

This is the method that inserts the string into string buffer. It always inserts a string at last position.
Here is the code of program
Output of program:
