是否继续观看（1/0）这个功能如何实现啊？

public abstract class Test {

//

public  static void show() {

// 初始显示界面提示部分

System.out.println("***************欢迎来到太阳马戏团***************");

System.out.println("***************  2、狮子  ***************");

System.out.println("***************  3、猴子  ***************");

System.out.println("***************  4、鹦鹉  ***************");

System.out.println("***************  5、小丑  ***************");

}

public static void main(String[] args) {

// 创建实例对象，并给相应属性传参

Bear one = new Bear("Bill", 1);

Lion two = new Lion("Lain", 2, "灰色", "公狮");

Monkey three = new Monkey("Tom", 1, "金丝猴");

Parrot four = new Parrot("Rose", 1, "牡丹鹦鹉");

Clown five = new Clown("Kahle", 5);

while (true) {

show();

int a = src.nextInt();

switch (a) {
