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() + "]"; } }
