Java Replace Character At Specific Position Of String?

Solution
Petar Ivanov's answer to replace a character at a specific index in a string question
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');
System.out.println(myName);
Problem
I am trying to replace a character at a specific position of a string. For example: ``` String str = "hi"; ``` replace string position #2 (i) to another letter "k" How would I do this? Thanks!
