java实现表格数据的存储

本文实例为大家分享了java实现表格数据存储的具体代码，供大家参考，具体内容如下

一、二维数组实现表格数据的存储

import java.util.arrays;

/**
 * 使用object[][]存储表格信息
 * @author lhk
 *
 */
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]));
 }
 
 }
}

二、javabean和数组存储表格信息

import java.util.arrays;

/**
 * 使用javabean和数组存储表格信息
 * @author lhk
 *
 */
public class array_test02 {
 public static void main(string args[]) {
 emps emp0=new emps(1001,"明明",20,"程序员","2021-03-28");
 emps emp1=new emps(1002,"花花",21,"程序员","2021-02-28");
 emps emp2=new emps(1002,"小李",19,"程序员","2021-04-01");
 
 emps[] emps={emp0,emp1,emp2};//静态初始化
 
 for(int i=0;i<emps.length;i++){
  system.out.println(emps[i].tostring());
 }
 }

}

class emps {
 private int id;
 private string name;
 private int age;
 private string job;
 private string hiretime;
 
 public emps(int id, string name, int age, string job, string hiretime) {
 super();
 this.id = id;
 this.name = name;
 this.age = age;
 this.job = job;
 this.hiretime = hiretime;
 }

 public emps() {
 super();
 }

 
 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 int getage() {
 return age;
 }

 public void setage(int age) {
 this.age = age;
 }

 public string getjob() {
 return job;
 }

 public void setjob(string job) {
 this.job = job;
 }

 public string gethiretime() {
 return hiretime;
 }

 public void sethiretime(string hiretime) {
 this.hiretime = hiretime;
 }

 
 @override
 public string tostring() {
 //重写tostring()方法可以用get方法来返回属性
 return "emps [id=" + getid() + ", name=" + getname() + ", age=" + getage() + ", job=" + getjob() + ", hiretime=" + gethiretime() + "]";
 }
 
}
