charAt( ) method when used with StringBuffer extracts the character from the specified string using the provided index.

Example:

StringBuffer object1 = new StringBuffer("abcdef");

object1.charAt(3);   -> Will extract the character at index 3 in the specified string "abcdef" i.e. 'd'

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

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