java使用Javabean和list結合存儲表格數據

測試使用Javabean和list結合存儲表格數據
體會orm思想
每行數據使用javabean對象存儲，多行使用放到map或者list中
id:1001姓名:張三薪水：20000.0入職日期：2018.5.5
id:1002姓名:李四薪水：2000.0入職日期：2005.5.5
id:1003姓名:萬三薪水：2300.0入職日期：2008.5.5

import java.util.ArrayList;
import java.util.Date;
import java.util.List;

public class TestStoreData2 {
	public static void main(String[] args) {
		User user1=new User(1001, "張三", 20000, "2018.5.5");
		User user2=new User(1002, "李四", 2000, "2005.5.5");
		User user3=new User(1003, "萬三", 2300, "2008.5.5");
		
		List<User> list=new ArrayList<>();
		list.add(user1);
		list.add(user2);
		list.add(user3);
		
		for(User u:list) {
			System.out.println(u);
		}
	}

}
//定義一個javabean對象
class User{
	private int id;
	private String name;
	private double salary;
	private String hiredate;
	
	
	//一個完整的javabean方法，要有set，get方法，以及無參數構造器
	public User(){
		
	}
	
	public User(int id, String name, double salary, String hiredate) {
		super();
		this.id = id;
		this.name = name;
		this.salary = salary;
		this.hiredate = hiredate;
	}

	//增加set，get方法
	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 double getSalary() {
		return salary;
	}
	public void setSalary(double salary) {
		this.salary = salary;
	}
	public String getHiredate() {
		return hiredate;
	}
	public void setHiredate(String hiredate) {
		this.hiredate = hiredate;
	}
	
	@Override
	public String toString() {
		// TODO Auto-generated method stub
		return "id:"+id+"姓名:"+name+"薪水："+salary+"入職日期："+hiredate;
	}
