1 package Homework; 2 3 public class TestFruit { 4 5 public static void main(String[] args) { 6 7 Fruit apple=new Fruit ("苹果","红色",5.5,"10g"); 8 apple.fruit(); 9 Fruit banana=new Fruit ("香蕉","黄色",4.2,"5g"); 10 banana.fruit(); 11 12 } 13 14 }
第二题:
定义一个人类,属性:姓名(name),性别(sex),年龄(age),
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

第三题:
定义一个桌子类,
属性: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
1 package Homework; 2 3 public class Table 4 { 5 private String material; 6 private String number; 7 private int price; 8 9 public String getMaterial() { 10 return material; 11 } 12 public void setMaterial(String material) { 13 this.material = material; 14 } 15 public String getNumber() { 16 return number; 17 } 18 public void setNumber(String number) { 19 this.number = number; 20 } 21 public int getPrice() { 22 return price; 23 } 24 public void setPrice(int price) { 25 this.price = price; 26 } 27 28 public Table(String material, String number, int price) { 29 super(); 30 this.material = material; 31 this.number = number; 32 this.price = price; 33 } 34 35 public void table(){ 36 System.out.println("型号:"+this.number+" 材质:"+this.material+" 价格:"+this.price+"元"); 37 System.out.println(); 38 } 39 }
1 package Homework; 2 3 public class TestTable { 4 5 public static void main(String[] args) { 6 7 Table t1=new Table("实木","S001",1000); 8 t1.table(); 9 Table t2=new Table("钢化玻璃","G002",300); 10 t2.table(); 11 12 } 13 14 }
第四题:
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
