Calling outer class function from inner class
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 Outer
method show
?
我如何调用该Outer
方法show
?

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();
