Final variable manipulation in Java

Question

Could anyone please tell me what is the meaning of the following line in context of Java:

final variable can still be manipulated unless it\'s immut

Answer 1

You can call any method on it even if the method can change the state of the object the reference is pointing to. E.g

final MyClass myClass = new MyClass();
myClass.setVar(something);

This is fine because myClass itself is not changing, i.e you are not doing myClass = myClass1;.
