Strings are immutable! But I can still modify and get a new copy of the original String? [closed]
String s = "PROJECT";

String s = "PROJECT";
String s2 = s.toLowerCase();

System.out.println(s.equals("PROJECT")); // Prints true
System.out.println(s.equals(s2));        // Prints false

MutableString ms = "PROJECT";
MutableString ms2 = ms.toLowerCase();

System.out.println(ms.equals("PROJECT")); // Prints false
System.out.println(ms.equals(ms2));       // Prints true
