OPP作业

1，定义一个水果类(fruit),水果类中的有
【属性】：颜色(color)、价格(price)、重量(weigth),
再定义一个<测试类>,
创建一个苹果(apple)的对象, 颜色是"红色",价格是5.5,重量10g。
然后再创建一个香蕉(banana)的对象,颜色是"黄色",价格是4.2,重量5g。
最后输出：
苹果的颜色、价格、重量、
香蕉的颜色、价格、重量、

package org.hanqi.pn0120;

public class Fruit {
    
      private String  color;
      
      private double price;
      
      private double weigth;

    public String getColor() {
        return color;
    }

    public void setColor(String color) {
        this.color = color;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public double getWeigth() {
        return weigth;
    }

    public void setWeigth(double weigth) {
        this.weigth = weigth;
    }

    public Fruit(String color, double price, double weigth) {
        super();
        this.color = color;
        this.price = price;
        this.weigth = weigth;
    }
      
    public static void main(String[] args)
    {
        Fruit apple=new Fruit( "红色",5.5,10);
        
        System.out.println("苹果的颜色是"+apple.getColor()+",价格是"+apple.getPrice()+"，重量是"+apple.getWeigth()+"g");
        
        Fruit banana=new Fruit("黄色",4.2,5);
        
        System.out.println("香蕉的颜色是"+banana.getColor()+",价格是"+banana.getPrice()+"，重量是"+banana.getWeigth()+"g");
    }

}

2、定义一个人类,人类中有以下属性:姓名(name),性别(sex),年龄(age),再定义一个测试类
创建一个"张三"的对象
姓名：张三
性别：男
年龄：20
创建一个"李四"的对象
姓名：李四
性别：女
年龄：21
最后输出张三与李四的信息

package org.hanqi.pn0120;

public class People {
    
    private String name;
    
    private String sex;
    
    private int age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public People(String name, String sex, int age) {
        super();
        this.name = name;
        this.sex = sex;
        this.age = age;
    }
    
    public static void main(String[] args){
        
        People people1=new People("张三","男",20);
        
        System.out.println("姓名："+people1.getName()+"
性别："+people1.getSex()+"
年龄："+people1.getAge());
        
        System.out.println();
        
        People people2=new People("李四","女",21);
        
        System.out.println("姓名："+people2.getName()+"
性别："+people2.getSex()+"
年龄："+people2.getAge());
        
    }
}

3、定义一个桌子类,属性有：材料、编号、价格,再定义一个测试类,在测试类中分别创建两张桌子,分别给他们赋值，最后输出

package org.hanqi.pn0120;

public class Desk {
    
       private String cailiao;
       
       private int binahao;
       
       private double price;

    public String getCailiao() {
        return cailiao;
    }

    public void setCailiao(String cailiao) {
        this.cailiao = cailiao;
    }

    public int getBinahao() {
        return binahao;
    }

    public void setBinahao(int binahao) {
        this.binahao = binahao;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public Desk(String cailiao, int binahao, double price) {
        super();
        this.cailiao = cailiao;
        this.binahao = binahao;
        this.price = price;
    }
       
       
    public static void  main(String[] args)
    {
        Desk  desk1=new Desk("红木",13,146.6);
        
        System.out.println("桌子的材料是"+desk1.getCailiao()+"，编号是"+desk1.getBinahao()+"，价格是"+desk1.getPrice()+"￥。");
        
        Desk  desk2=new Desk("榆木",92,54.2);
        
        System.out.println("桌子的材料是"+desk2.getCailiao()+"，编号是"+desk2.getBinahao()+"，价格是"+desk2.getPrice()+"￥。");
        
    }
}

4,写一个传奇游戏中的猪类，类中有属性：颜色(color)、重量(weight)、攻击力(attack)、准确度(accuracy)。再写一个测试类，生成一个猪的对象，将此猪的颜色值为“白色(white)”，重量为5，攻击力为50点，准确度为0.8。要求输出此猪的信息格式为：一只白色的猪，重量5，攻击为50点血，准确度为0.8，我好怕怕呀!

package org.hanqi.pn0120;

public class Pig {
    
    private String color;
    
    private double weight;
    
    private int attack;
    
    private double accuracy;

    public String getColor() {
        return color;
    }

    public void setColor(String color) {
        this.color = color;
    }

    public double getWeight() {
        return weight;
    }

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

    public int getAttack() {
        return attack;
    }

    public void setAttack(int attack) {
        this.attack = attack;
    }

    public double getAccuracy() {
        return accuracy;
    }

    public void setAccuracy(double accuracy) {
        this.accuracy = accuracy;
    }

    public Pig(String color, double weight, int attack, double accuracy) {
        super();
        this.color = color;
        this.weight = weight;
        this.attack = attack;
        this.accuracy = accuracy;
    }

    public static void main(String[] args) {
        
        Pig pig=new Pig("白色",5,50,0.8);
        
        System.out.println("一只"+pig.getColor()+"的猪，重量"+pig.getWeight()+"，"
        + "为"+pig.getAttack()+"点血，准确度为"+pig.getAccuracy()+"，我好怕怕呀!");
        
    }

}
