(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);
