147. Using 'setCharAt( )' method with StringBuffer

setCharAt( )  method when used with StringBuffer replaces the character with another at the specified index.


StringBuffer object1 = new StringBuffer("man");

object1.setCharAt(1,'e');  -> This will replace the character available at the provided index '1' in the specified string "man" i.e. 'a' with another character 'e'. The resultant string after replacement is "men"

Lets implement this on Eclipse IDE:

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

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