根据下列要求定义接口和类：接口canSwim具有一个方法void swim()，接口canJump具有一个方法void jump()，类Frog实现接口canJump和canSwim，实现方法时只需要做输出打印即可。

 

package cn.test4;

interface canSwim{
    public void swim();
}

interface canJump{
    public void jump();
}

class Flog implements canJump,canSwim{

    @Override
    public void swim() {
        System.out.println("swim");
    }

    @Override
    public void jump() {
        System.out.println("jump");
    }
}
public class test {


    public static void main(String[] args) {
        Flog flog = new Flog();
        flog.swim();
        flog.jump();
    }
}
