使用object[][]储存整个表格的数据

package Testshuzubianli;import java.util.Arrays;public class Test04 {public static void main(String[] args) {Object[]  emp0 = {1001,"yi",20,"程序员","2020.06.04"};Object[]  emp1 = {1001,"er",21,"程序员","2020.06.04"};Object[]  emp2 = {1001,"san",22,"程序员","2020.06.04"};Object[][] emps = new  Object[3][];emps[0] = emp0;emps[1] = emp1;emps[2] = emp2;for (int i = 0;i<emps.length;i++){System.out.println(Arrays.toString(emps[i]));}//使用嵌套循环打印for (int i = 0;i<emps.length;i++){System.out.println();for (int j= 0;j<emps[i].length;j++){System.out.print(emps[i][j]+"\t");}}}
}

运行结果：

[1001, yi, 20, 程序员, 2020.06.04]
[1001, er, 21, 程序员, 2020.06.04]
[1001, san, 22, 程序员, 2020.06.04]1001	yi	20	程序员	2020.06.04	
1001	er	21	程序员	2020.06.04

使用javabean和数组存储表格的信息

package Testshuzubianli;/*** 使用javabean和数组存储表格的信息*/
public class Test05 {public static void main(String[] args) {emp  emp0 = new emp(1001,"夏",20,"程序员","2020.06.04");emp  emp1 = new emp(1002,"他",21,"程序员","2020.06.04");emp  emp2 = new emp(1003,"分",22,"程序员","2020.06.04");emp[] emps = new emp[]{emp0, emp1, emp2};for (int i= 0;i<emps.length;i++){System.out.println(emps[i]);}}
