Java匿名内部类继承类和实现接口

//实现接口
public interface MyInterface {
    void pri();
}

public class TestClass1 {
    public MyInterface test(){
        return new MyInterface(){
            public void pri() {
                System.out.println(1);
            }
        };
    }
    public static void main(String[] args) {
        MyInterface my =  new TestClass1().test();
        my.pri();
    }
}

//继承类
public abstract class AbstructClass {
    abstract void pri();
}

public class TestClass2 {
    public AbstructClass te(){
        return new AbstructClass(){
            void pri() {
                System.out.println(1);
            }
        };
        
    }
    public static void main(String[] args) {
        AbstructClass abc = new TestClass2().te();
        abc.pri();
    }
}
