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：
