如图所示java编程，多谢老哥

static abstract class Animal {
    abstract void eat();
}

static class Elephant extends Animal {

    @Override
    void eat() {
        System.out.println("大象是吃草的动物！");
    }
}

static class Lion extends Animal {

    @Override
    void eat() {
        System.out.println("狮子是吃肉的动物！");
    }
}

static class Test {
    public static void main(String[] args) {
        Elephant elephant = new Elephant();
        elephant.eat();
        
        Lion lion = new Lion();
        lion.eat();
    }
}

你既然在学习，就自己先动过手写一下
