java实现表格数据的存储

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hkSqgGoIPW

for(int i=0;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 {

puhkSqgGoIPWblic 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

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 jobhttp://, 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() + ", http://Hiretime=" + getHiretime() + "]";

}

}

System.out.println(Arrays.toString(emps[i]));

}

}

}
