[上]JAVA学习系列模块八第二章163.封装_快速编写javabean快捷键

视频

笔记

[tip type=”info” display=”custom-class”]编写符合`JavaBean` 规范的类，以学生类为例，标准代码如下：[/tip]

public class Student {
    private int sid;
    private String sname;

    public Student() {
    }

    public Student(int sid, String sname) {
        this.sid = sid;
        this.sname = sname;
    }

    public int getSid() {
        return sid;
    }

    public void setSid(int sid) {
        this.sid = sid;
    }

    public String getSname() {
        return sname;
    }

    public void setSname(String sname) {
        this.sname = sname;
    }
}

快速生成标准javabean通用快捷键:alt+insert

生成无参构造:

生成有参构造

生成get/set方法:

public class Test01 {
    public static void main(String[] args) {
        Student s1 = new Student();
        s1.setSid(1);
        s1.setSname("涛哥");
        System.out.println(s1.getSid()+"..."+s1.getSname());

        System.out.println("==============");

        Student s2 = new Student(2, "金莲");
        System.out.println(s2.getSid()+"..."+s2.getSname());
    }
}
