Immutable means if you apply any methods to a String, it
would not affect the original String you created.
For eg,
String s = "test";
s.concat(" two");
System.out.println(s);
The output is still "test" and not "test two";
Java pass by reference. If you use = to assign the string
to another string, then the reference would change.
Therefore your example changes the string.
