夜光序言：
都说物是人非，有时候，明明那物还在，人却面目全非，连当日的那颗心也不知何时起开始学会遗忘和麻木~~
正文：
package com.Genius.sixth;
public class CreateObjectTest {
public static void main(String[] args) {
// 夜光：我们学习如何创建对象，并且使用~~
// 深入对象精髓
Cup cup = new Cup();
System.out.println("夜光他对杯子没有要求~~");
Cup cupph = new Cup("红色",15);
System.out.println("一个高为18cm的红色杯子");
Cup cuppc = new Cup(10.0,15);
System.out.println("一个高为18cm的红色杯子");
Cup cuppch = new Cup(10.0,"红色",18);
System.out.println("一个价格为10元高为18cm的红色杯子~~");
}
}
class Cup{
private int high;
private String color;
private double price;
public Cup(){
}
public Cup(String color,int high){
this.color = color;
this.high = high;
}
public Cup(double price,int high){
this.price = price;
this.high = high;
}
public Cup(double price,String color){
this.price = price;
this.color = color;
}
public Cup(double price,String color,int high){
this.price = price;
this.color = color;
this.high = high;
}
}
我们先写第一个类：
package com.Genius.sixth;
public class TestCup {
public String color = "红色";
public int high = 18;
public double price = 10.0;
public TestCup(){
}
public TestCup(String color,int high,double price){
this.color = color;
this.high = high;
this.price = price;
}
//夜光：我们再写一个方法~~
public void water(){
System.out.println("夜光使用杯子喝水~~");
}
}
之后我们再写一个一个类：
package com.Genius.sixth;
public class CupTest {
public static void main(String[] args) {
TestCup ct = new TestCup();
ct.high = 1111;
ct.color = "中国红~~";
ct.price = 1111;
System.out.println("一个价格为"+ct.price
+"元，高为"+ct.high+"米的"+ct.color+
"杯子"
);
ct.water();
}
}
