使用容器存储表格数据

?

?

思路：每一行使用一个map，整张表使用一个list。

ORM思想：对象映射关系

?

范例：

package cn.sxt.collection;

import java.util.*;

public class testStore { public static void main(String[] args) { Map<String,Object> row1 = new HashMap<String,Object>(); row1.put("ID",1001); row1.put("姓名","张三"); row1.put("薪水",20000); row1.put("入职日期","2018.5.5"); Map<String,Object> row2 = new HashMap<String,Object>(); row2.put("ID",1002); row2.put("姓名","李四"); row2.put("薪水",30000); row2.put("入职日期","2005.4.4"); Map<String,Object> row3 = new HashMap<String,Object>(); row3.put("ID",1003); row3.put("姓名","王五"); row3.put("薪水",3000); row3.put("入职日期","2020.5.4"); List<Map<String,Object>> list = new ArrayList<Map<String,Object>>(); list.add(row1); list.add(row2); list.add(row3); for (Map<String,Object> row:list) { Set<String> keySet = row.keySet(); for (String key:keySet) { System.out.print(key+":"+row.get(key)+"tt"); } System.out.println(); } }}
