Java: equivalent to C++ const method

Question

In C++, one can define a const method:

class MyClass {
    void myMethod() const {
        .. code ..
    };
};

The const here means that this method has only read permissions to this. I.e., it cannot make any change to the object it works on. It can only make read operations on it.

Is there an equivalent in Java for const method?

@ifLoop I was gonna blab out 'final' but realised that it is for class inheritence stuff....:P...so deleted my comment — ha9u63a7, Oct 27 '14 at 14:20
There's no such thing in Java. Just make sure you don't modify "this". A plain "getter" in Java will do the job.. — Brandon, Oct 27 '14 at 14:23

Creating an answer from my comment: There is no equivalent for this in java.

A member function has always write access to the fields of it's class. If you want to change that behavior, you have to move the function outside the class and hand over a copy to it.
