匿名内部类的简单使用

1.  new 一个抽象的类：

package com.xuzhiwen.test1;

abstract class Person {
    abstract void eat();
}

package com.xuzhiwen.test1;

public class TestPerson {
    public static void main(String[] args) {
        Person p = new Person() {
            @Override
            void eat() {
                System.out.println("i can eat");
            }
        };
        p.eat();
    }
}

2. new 一个接口：

package com.xuzhiwen.test1;

public interface Animal {
    public void run();
}

package com.xuzhiwen.test1;

public class Dog {
    public static void main(String[] args) {
        new Animal() {
            
            @Override
            public void run() {
                System.out.println("run()..");
            }
            
            public void getName(){
                System.out.println("getName()...");
            }
        }.getName();
    }
}
