OOP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、

编写代码如下：

定义水果类：

package org.hanqi.pn0120;

public class Fruit {
    
    private String color;
    private double price;
    private int weight;
    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 int getWeight() {
        return weight;
    }
    public void setWeight(int weight) {
        this.weight = weight;
    }
}

定义测试类：

package org.hanqi.pn0120;

public class TestFruit {

    public static void main(String[] args) {
        
        Fruit apple = new Fruit();
        apple.setColor("红色");
        apple.setPrice(5.5);
        apple.setWeight(10);
        System.out.println("苹果的颜色是："+apple.getColor()+" ,价格是："+apple.getPrice()+" ,重量是："+apple.getWeight()+"g");
        Fruit banana = new Fruit();
        banana.setColor("黄色");
        banana.setPrice(4.2);
        banana.setWeight(5);
        System.out.println("香蕉的颜色是："+banana.getColor()+" ,价格是："+banana.getPrice()+" ,重量是："+banana.getWeight()+"g");
    }
}

则运行结果为：

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

编写代码如下：

定义一个人类：

package org.hanqi.pn0120;

public class Human {
    
    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 Human(String name, String sex, int age) {
        super();
        this.name = name;
        this.sex = sex;
        this.age = age;
    }
    public void human()
    {
        System.out.println("姓名："+this.name+" ，性别："+this.sex+" ，年龄："+this.age);
    }
}

再定义一个测试类：

package org.hanqi.pn0120;

public class TestHuman {

    public static void main(String[] args) {
        
        Human zhangsan = new Human("张三","男",20);
        zhangsan.human();
        Human lisi = new Human("李四","女",21);
        lisi.human();
    }
}

则运行结果为：

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

编写代码如下：

定义一个桌子类：

package org.hanqi.pn0120;

public class Desk {
    
    private String stuff;
    private int number;
    private double price;
    public String getStuff() {
        return stuff;
    }
    public void setStuff(String stuff) {
        this.stuff = stuff;
    }
    public int getNumber() {
        return number;
    }
    public void setNumber(int number) {
        this.number = number;
    }
    public double getPrice() {
        return price;
    }
    public void setPrice(double price) {
        this.price = price;
    }
}

再定义一个测试类：

package org.hanqi.pn0120;

public class TestDesk {

    public static void main(String[] args) {
            
        Desk desk1 = new Desk();
        desk1.setStuff("木制");
        desk1.setNumber(9527);
        desk1.setPrice(666);
        System.out.println("第一张桌子的材质是："+desk1.getStuff()+"，编号是："+desk1.getNumber()+"，价格是："+desk1.getPrice());
        Desk desk2 = new Desk();
        desk2.setStuff("铁制");
        desk2.setNumber(27149);
        desk2.setPrice(233);
        System.out.println("第二张桌子的材质是："+desk2.getStuff()+"，编号是："+desk2.getNumber()+"，价格是："+desk2.getPrice());        
    }
}

运行结果为：

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

编写代码如下：

定义一个猪类：

package org.hanqi.pn0120;

public class Pig {
    
    private String color;
    private int weight;
    private int attack;
    private double accuracy;
    public String getColor() {
        return color;
    }
    public void setColor(String color) {
        this.color = color;
    }
    public int getWeight() {
        return weight;
    }
    public void setWeight(int 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, int weight, int attack, double accuracy) {
        super();
        this.color = color;
        this.weight = weight;
        this.attack = attack;
        this.accuracy = accuracy;
    }
    public void pig()
    {
        System.out.println("一只"+this.color+"的猪，重量"+this.weight+"，攻击力为"+this.attack+"点血，准确度为"+this.accuracy+",我好怕怕呀");
    }
}

再定义测试类：

package org.hanqi.pn0120;

public class TestPig {

    public static void main(String[] args) {
        
        Pig pig = new Pig("白色",5,50,0.8);
        pig.pig();
    }
}

则运行结果为：
