编写一个Java应用程序该程序包括3个类：Monkey类、People类和测试类Test。要求： 1Monkey类中有个构造方法： MonkeyString s并且有个voidspeak0方法在speak方法中输出吱吱咋咋的信息。 2People类是Monkey类的子类在People类中重写方法speak0在speak方法中输出我会说话了哈哈！的信息。 3在People类中新增方法voidthin

Monkey类：

public class Monkey {
    private String name;
    
    public Monkey(String s) {
        name = s;
    }
    
    public void speak() {
        System.out.println(name + "：吱吱，咋咋！");
    }
}

People类：

public class People extends Monkey {
    public People(String s) {
        super(s);
    }
    
    @Override
    public void speak() {
        System.out.println(super.name + "：我会说话了，哈哈！");
    }
    
    public void think() {
        System.out.println(super.name + "：别说话！认真思考！");
    }
}

Test类：

public class Test {
    public static void main(String[] args) {
        Monkey monkey = new Monkey("猴子");
        People people = new People("人类");
        
        monkey.speak();
        people.speak();
        people.think();
    }
}
