[java] Replace a character at a specific index in a string?

I'm trying to replace a character at a specific index in a string.

What I'm doing is:

String myName = "domanokz";
myName.charAt(4) = 'x';

This gives an error. Is there any method to do this?

The answer is

String are immutable in Java. You can't change them.

You need to create a new string with the character replaced.

String myName = "domanokz";
String newName = myName.substring(0,4)+'x'+myName.substring(5);

Or you can use a StringBuilder:

StringBuilder myName = new StringBuilder("domanokz");
myName.setCharAt(4, 'x');
