java - 扩展动物的猎豹类。爪哇

问题描述

Cheetah 扩展程序不会运行。它提供了所有的狮子输出。但是猎豹不会输出。它运行良好，因为它没有错误，它只是绕过了 cheetah 继承并且不会输出它。

为此任务修改现有的 Animal.java 文件。

创建一个名为“Cheetah”的类：
继承自 Animal 类。
使用至少一个需要静态 setter 和 getter 的静态字段。
包含一个构造函数。
包含一个 toString() 方法。
有一个数组作为它的字段之一。
创建一个应用程序类，并在其中创建一个 Cheetah 对象并使用 main 方法打印出来。

所有的一切都在那里，猎豹就不会跑了。

    public class Animal {
    private int numTeeth = 0;
    private boolean spots = false;
    private int weight = 0;

    public Animal(int numTeeth, boolean spots, int weight){
        this.setNumTeeth(numTeeth);
        this.setSpots(spots);
        this.setWeight(weight);
    }

    public int getNumTeeth(){
        return numTeeth;
    }

    public void setNumTeeth(int numTeeth) {
        this.numTeeth = numTeeth;
    }

    public boolean getSpots() {
        return spots;
    }

    public void setSpots(boolean spots) {
        this.spots = spots;
    }

    public int getWeight() {
        return weight;
    }

    public void setWeight(int weight) {
        this.weight = weight;
    }

    public static void main(String[] args){
        Lion lion = new Lion(30, false, 80);
        System.out.println(lion);
    }

    public static void main1(String[] args){
        Cheetah cheetah = new Cheetah(30, true, 45);
        System.out.println(cheetah);
    }

}

狮子班

 class Lion extends Animal {
    String type = "";

    public Lion(int numTeeth, boolean spots, int weight) {
        super(numTeeth, spots, weight);
        type(weight);
    }
    public String type(int weight){
        super.setWeight(weight);
        if(weight <= 80){
            type = "Cub"; 
        }
        else if(weight <= 120){
            type = "Female";
        }
        else{
            type = "Male";
        }
        return type;
    }
    @Override
    public String toString() { 
        String output = "Number of Teeth: " + getNumTeeth(); 
        output += "\nDoes it have spots?: " + getSpots();
        output += "\nHow much does it weigh: " + getWeight();
        output += "\nType of Lion: " + type;
        return output;
    }
}

猎豹类：

 class Cheetah extends Animal {         

        public Cheetah(int numTeeth, boolean spots, int weight) {
            super(numTeeth, spots, weight);
        }

        public String toString(String cheetah) { 
            String output = "Number of Teeth: " + getNumTeeth(); 
            output += "\nDoes it have spots?: " + getSpots();
            output += "\nHow much does it weigh: " + getWeight();
            output += "\nCheetah";
            return output;
 }
 }
