1. package com.hotpot.main;
2. public class SimpleBean{
3. private String name;
4. private int age;
5. public void setName(String name){
6. this.name = name;
7. }
8. public void setAge(int age){
9. this.age = age;
10. }
11. public String getName(){
12. return this.name;
13. }
14. public int getAge(){
15. return this.age;
16. }
17.}
如果在一个类中只包含属性、setter、getter方法，那么这种类就成为简单JavaBean。

package model; public class Bean { private String message="默认default"; public String getMessage() { return(message); } public void setMessage(String message) { this.message = message; } }
