java编程几个类，可以实现动物园中几个科下动物的增删改查

相关问答
Q1: 动物园编程题java，有6个java程序
这种类型动物园Java代码的题目考查动物园Java代码的应该是继承和多态的思想动物园Java代码，首先编写动物类动物园Java代码，然后其余的继承那个动物类动物园Java代码，主函数生成动物对象，依次调用各自的方法即可
Q2: 编写Java程序，用来描述动物园里的猴子。要求如下 （1） 创建一个Monkey（猴子）类，其属性包括颜色和性别
public class Monkey {
private String color;
private String sex;
public Monkey(String color,String sex) {
this.color = color;
this.sex = sex;
}
public Monkey(String color) {
this.color = color;
this.sex = "公";
}
public Monkey(){}
public String getColor() {
return color;
}
public void setColor(String color) {
this.color = color;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public int add(int p1,int p2,int p3) {
return p1+p2+p3;
}
public int add(int p1,int p2) {
return p1+p2;
}
}
public class Zoo {
public static void main(String[] args) {
Monkey g = new Monkey("黑");
Monkey l = new Monkey("红","母");
int p1 = g.add(1, 2);
int p2 = l.add(1, 2, 3);
System.out.println(g.getSex()+":"+p1);
System.out.println(l.getSex()+":"+p2);
}
}
Q3: 用java编一个关于动物园的程序
应用程序什么时候结束取决于你一开始创建了多少动物？？？
从你的描述看来，无论有多少只动物，最长命的动物的寿命即是程序的寿命了。
