Calling outer class function from inner class

I have implemented a nested class in Java, and I need to call the outer class method from the inner class.

class Outer {
    void show() {
        System.out.println("outter show");
    }

    class Inner{
        void show() {
            System.out.println("inner show");
        }
    }
}

How can I call the Outer method show?

You need to prefix the call by the outer class:

Outer.this.show();

This should do the trick:

Outer.Inner obj = new Outer().new Inner();
obj.show();
