}

下面是类Persion的定义：


package com.cn.domain;

public class Persion {
	private int id;
	private String name;
	private short age;
	
	public Persion(){
		
	}
	
	public Persion(int id, String name, short age) {
		super();
		this.id = id;
		this.name = name;
		this.age = age;
	}
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public short getAge() {
		return age;
	}
	public void setAge(short age) {
		this.age = age;
	}
	@Override
	public String toString() {
		return "Persion [age=" + age + ", id=" + id + ", name=" + name + "]";
	}
}
