java – 编程POJO和Bean之间的区别

1)POJO类,因为它只有getter和setter方法,所有成员都声明为private

public class POJO {
    private int id;
    private String name;

    public int getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public void setId() {
        this.id = id;
    }

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

2)Bean类 – 所有成员变量都是私有的,具有getter和setter并实现Serializable接口

public class Bean implements java.io.Serializable {
    private String name;
    private Integer age;

    public String getName() {
        return this.name;
    }

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

    public Integer getAge() {
        return this.age;
    }

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

它还有一个无参数构造函数.
