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();
}

}
