public class Array_Test01 {
public static void main(String args[]){
//一个Object[]数组代表表格的一行数据
//此处的基本数据类型1001，1002,1003本质不是Object对象，Java编译会自动把基本数据类型“自动装箱”成包装类对象
Object[] emp0={1001,"明明",20,"程序员","2021-03-28"};
Object[] emp1={1002,"花花",21,"程序员","2021-02-28"};
Object[] emp2={1002,"小李",19,"程序员","2021-04-01"};
Object[][] emps=new Object[3][];
emps[0]=emp0;
emps[1]=emp1;
emps[2]=emp2;
//遍历数组（可用嵌套循环遍历多维数组），输出表格
for(int i=0;i<emps.length;i++){
System.out.println(Arrays.toString(emps[i]));
}
}
