/*1.定义一个汽车类（Car），属性有颜色，品牌，车牌号，价格，并实例化两个对象，给属性赋值，并输入属性值*/package com.Oracle.oop1;public class Car {String color;String brand;String number;int price;}package com.Oracle.oop1;public class Text1 {public static void main(String[] args) {Car c1=new Car();c1.color="blue";c1.brand="Audi";c1.number="黑A888888";c1.price=88888;Car c2=new Car();c2.color="yellow";c2.brand="BMW";c2.number="黑B888888";c2.price=66666;System.out.print(c1.color+"\t");System.out.print(c1.brand+"\t");System.out.print(c1.number+"\t");System.out.println(c1.price+"\t");System.out.print(c2.color+"\t");System.out.print(c2.brand+"\t");System.out.print(c2.number+"\t");System.out.print(c2.price+"\t");}}

/*2.定义一个球员类(Player)，属性有身高，体重，姓名，实例化两个球员，分别是姚明和科比；*/package com.Oracle.oop1;public class Player {int height;int weight;String name;}package com.Oracle.oop1;public class Text2 {public static void main(String[] args) {Player p1=new Player();p1.name="姚明";p1.height=210;p1.weight=85;Player p2=new Player();p2.name="科比";p2.height=210;p2.weight=88;System.out.print(p1.name+"\t");System.out.print(p1.height+"\t");System.out.println(p1.weight+"\t");System.out.print(p2.name+"\t");System.out.print(p2.height+"\t");System.out.print(p2.weight+"\t");}}

/*3.定义一个僵尸类(Zombie)，属性有名子，体力值，攻击力，实例化三个僵尸类，并给属性赋值；*/package com.Oracle.oop1;public class Zombie {String name;int power;int ATK;void  print() {System.out.print("名字："+name);System.out.print("\t体力值："+power);System.out.println("\t攻击值："+ATK);}}package com.Oracle.oop1;public class Text3 {public static void main(String[] args) {Zombie z1=new Zombie();Zombie z2=new Zombie();Zombie z3=new Zombie();z1.name="铁桶僵尸";z1.power=200;z1.ATK=300;z2.name="孕妇僵尸";z2.power=300;z2.ATK=250;z3.name="超级僵尸";z3.power=888;z3.ATK=888;z1.print();z2.print();z3.print();}}

//4.打印int，char， float，double，String ，boolean这些数据类型作为类属性时的默认值package com.Oracle.oop1;public class Default {int int1;char char1;float float1;double double1;String string1;boolean bool;}package com.Oracle.oop1;public class Text4 {public static void main(String[] args) {Default d=new Default();System.out.println(d.int1);System.out.println(d.char1);System.out.println(d.float1);System.out.println(d.double1);System.out.println(d.string1);System.out.println(d.bool);}}
