JavaBean是什么

import java.io.Serializable;

public class Student implements Serializable {
    // 实现序列号接口
    private static final long serialVersionUID = 799887342985222720L;

    // 提供私有修饰的成员变量
    private String name;
    private int age;
    private String gender;

    // 提供公共无参的构造
    public Student() {
    }

    // 为成员变量提供公共getter和setter方法
    public String getName() {
        return name;
    }

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

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }
}
