夜光序言：
巨大的财富对于一个不惯于掌握钱财的人，是一种毒害，它侵入他的品德的血肉和骨髓~~
所以呢，品德很重要，人品乃人之精髓
正文：
package com.Genius.sixth;
/*夜光：我们先写一个对象~~*/
public class Genius {
public String name = "夜光";
public String sex = "男";
public int age = 23;
public String address = "深圳市高新技术产业园";
public Genius(){
}
public Genius(String name,String sex,int age,String address){
this.name = name;
this.age = age;
this.sex = sex;
this.address = address;
}
public String eat(){
return "夜光正在休憩~~";
}
}
上面是我们写的第一个类~~
下面我们再写一个运行类~~
package com.Genius.sixth;
/*夜光：我们再写一个测试的~~*/
public class GeniusTest {
public static void main(String[] args) {
Genius genius = new Genius();
System.out.println("个人信息输出~~");
System.out.println("姓名"+genius.name);
System.out.println("性别"+genius.sex);
System.out.println("年龄"+genius.age);
System.out.println("地址"+genius.address);
System.out.println(genius.name+"在调情~~");
System.out.println(genius.eat());
}
}
【通过这些可以对对象有一定了解，java就是new++，不断new对象】
夜光练习1：
以一个日志为例，介绍类的基本组成结构和使用方法，日志中可以存储姓名，性别，地址等~~
package com.Genius.sixth;
public class DemoTest {
String name;
String sex;
String address;
public DemoTest(String name,String sex,String address){
this.name = name;
this.sex = sex;
this.address = address;
}
public void printMessage(){
System.out.println("姓名"+name);
System.out.println("性别"+sex);
System.out.println("地址"+address);
}
public static void main(String[] args) {
DemoTest cd = new DemoTest("Genius","男","深圳市高新技术产业园");
cd.printMessage();
}
}
夜光练习2：
package com.Genius.sixth;
public class Student {
//编写一个学生类，注意保留无参数构造~~
private String name;
private String gender;
private int age;
public Student(){
}
public Student(String name,String gender,int age){
this.name = name;
this.gender = gender;
this.age = age;
}
}
package com.Genius.sixth;
public class Student {
//编写一个学生类，注意保留无参数构造~~
private String name;
private String gender;
private int age;
public Student(){
}
public Student(String name,String gender,int age){
this.name = name;
this.gender = gender;
this.age = age;
}
public String read(String content){
String mine = "Genius works hard";
String remain = mine + content;
System.out.println("这是我学到的内容"+content);
return remain;
}
public String write(String content){
System.out.println("这书写的内容："+content);
return content;
}
public static void main(String[] args) {
Student king = new Student();
king.read("1");
}
}
======================================================================
学编程就是要有兴趣，要有好奇心~~
我们再写一个teacher类，调用上面方法~~
public class Teacher {
String content = "This is the knowledge to teach:";
private void check(Student student) {
student.read(content);
student.write(content);
}
}
皮一下~~
