java（标准javabean的书写）

标准javabean书写要求：

1.所有javabean必须在同一个包中

2.javabean必须生成public class类，文件名与类名一致

3.成员变量都使用private修饰

4.每一个属性提供成员变量对应的get/setXXX()方法

5.提供无参构造器，有参构造器可以有可以无

6..快捷键，鼠标右键constructor或者alt+ins可以生成

package com.yuyang.javabean;

public class User {
    private String name;
    private double height;
    private double salary;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public double getHeight() {
        return height;
    }

    public void setHeight(double height) {
        this.height = height;
    }

    public double getSalary() {
        return salary;
    }

    public void setSalary(double salary) {
        this.salary = salary;
    }

    public User(String name, double height, double salary) {
        this.name = name;
        this.height = height;
        this.salary = salary;
    }

    public User() {
    }
}

package com.yuyang.javabean;

public class Test1 {
    public static void main(String[] args) {
        User u=new User();
        u.setName("张三");
        u.setHeight(183.6);
        u.setSalary(10000);
        System.out.println(u.getHeight());
        System.out.println(u.getName());
        System.out.println(u.getSalary());
        User s=new User("张三",193.3,20000);
        System.out.println(s.getHeight());
        System.out.println(s.getName());
        System.out.println(s.getSalary());

    }
}
