// You cannot change the characters of a string in java
// But you can make it work
// For Example: A Program to change 'r' to 'a'
class Main{
  public static void main(String args[]){
    String str = "return";
    String res = "";
    for(int i = 0; i<str.length(); i++){
      if(str.charAt(i)=='r'){
        res+='a';
      }
      else{
        res+=str.charAt(i);
      }
    }
    System.out.print("Result = "+res);
  }
}

how to change single character of a string in java

Comment

//short answer: you cannot individually change any specific character
//of a String in java. You can however do this:

String s1 = "This is a String";
String s2 = s1.substring(0, 8) + "o" + s1.substring(9);
System.out.println(s2);
//Prints "This is o String", replaced the 8th character with an o
