10.匿名内部类的应用场景

匿名内部类作为参数传递

package com.itheima_04;

public interface Animal {
    public abstract void eat();
}

package com.itheima_04;

public class Cat implements Animal {

    @Override
    public void eat() {
        System.out.println("猫吃鱼");
    }

}

package com.itheima_04;

public class Dog implements Animal {

    @Override
    public void eat() {
        System.out.println("狗啃骨头");
    }

}

package com.itheima_04;

public class InnerDemo5 {

        method(new Animal() {
