Calling outer class function from inner class

java

提问by Santhosh

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

我在Java中实现了一个嵌套类,需要从内部类调用外部类的方法。

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

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

How can I call the Outermethod show?

我如何调用该Outer方法show

采纳答案by Guillaume

You need to prefix the call by the outer class:

您需要通过外部类为调用添加前缀:

Outer.this.show();

回答by vijay surya

This should do the trick:

这应该可以解决问题:

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