代码如下

public class Test{
    public static void main(String[] args){
        Outer out = new Outer();
        out.method();
    }
}

interface Inner {
    public void show1();
    public void show2();
}
    
class Outer{
    public void method(){
        new Inner(){
            public void show1(){
                System.out.println("show1()");
            }
            
            public void show2(){
                System.out.println("show2()");
            }
        }.show1();
    }
}
