使用java面向对象创建动物类并输出动物信息

import java.util.Scanner;
public class Animal{
private double weight;//体重
private int leg;//腿的数量
private String color;//颜色
private Animal[] animals;//声明一个数组，用来存储几个动物

public void setWeight(double weight){
this.weight=weight;
}
public double getWeight(){
return weight;
}
public void setLeg(int leg){
this.leg=leg;
}
public int getLeg(){
return leg;
}
public void setColor(String color){
this.color=color;
}
public String getColor(){
return color;
}

//初始化动物
public void initAnimal(){
Scanner scanner=new Scanner(System.in);
System.out.println("-----------------请输入动物的信息--------------------");
animals=new Animal[3];
int j=1;
for(int i=0;i<animals.length;i++){
Animal an=new Animal();
System.out.println("请输入"+j+"动物的信息:");
System.out.println("体重:");
double weight=scanner.nextDouble();
an.setWeight(weight);
System.out.println("脚数:");
int leg=scanner.nextInt();
an.setLeg(leg);
System.out.println("颜色:");
String color=scanner.next();
an.setColor(color);
animals[i]=an;
j++;
}
//打印动物信息
for(int a=0;a<animals.length;a++){
Animal animal=animals[a];
System.out.println("第"+(a+1)+"只动物的信息:");
System.out.println("体重: "+animal.getWeight());
System.out.println("脚数: "+animal.getLeg());
System.out.println("颜色: "+animal.getColor());
}
}
public static void main(String[] args){
Animal an=new Animal();
an.initAnimal();
}
}
