- 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 oop_ShiYanYi;
class Car{
String color;
String brand;
int prise;
String id;
}
public class _1 {
public static void main(String[] args) {
// TODO Auto-generated method stub
Car car = new Car();
car.brand = "五菱红光";
car.color = "bule";
car.id = "黑A88888";
car.prise = 99999999;
System.out.println("车的品牌是："+car.brand);
System.out.println("车的颜色是："+car.color);
System.out.println("车的车牌号是："+car.id);
System.out.println("车的价格是："+car.prise);
}
}
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 oop_ShiYanYi;
import java.util.Set;
class Player{
double height;
double weight;
String name;
public double getHeight() {
return height;
}
public void setHeight(double height) {
this.height = height;
}
public double getWeight() {
return weight;
}
public void setWeight(double weight) {
this.weight = weight;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
public class _2 {
public static void main(String[] args) {
// TODO Auto-generated method stub
Player play = new Player();
play.setName("姚明");
play.setHeight(2.26);
play.setWeight(220);
System.out.println("运动员姓名："+play.getName());
System.out.println("运动员身高："+play.getHeight()+"米");
System.out.println("运动员体重："+play.weight+"kg");
}
}
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 oop_ShiYanYi;
class Zomibie{
String name;
int power;
int attack;
}
public class _3 {
public static void main(String[] args) {
// TODO Auto-generated method stub
Zomibie z1 = new Zomibie();
z1.name = "铁通僵尸";
z1.power = 100;
z1.attack = 10;
System.out.println("姓名："+z1.name);
System.out.println("体力值："+z1.power);
System.out.println("攻击力："+z1.attack);
}
}
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 oop_ShiYanYi;
class Default{
int int1;
double double1;
char char1;
float float1;
String String1;
boolean boo;
}
public class _4 {
public static void main(String[] args) {
// TODO Auto-generated method stub
Default d = new Default();
System.out.println(d.int1);
System.out.println(d.double1);
System.out.println(d.char1);
System.out.println(d.float1);
System.out.println(d.String1);
System.out.println(d.boo);
}
}
