篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Java实验项目三——面向对象定义职工类和日期类相关的知识,希望对你有一定的参考价值。
Program:按照如下要求设计类:
(1)设计一个日期类,用于记录年、月、日,并提供对日期处理的常用方法。
(2)设计一个职工类,该职工类至少具有下面的属性:职工号,姓名,性别,生日,工作部门,参加工作时间,设计相应的方法。
(3)设计一个测试类,采用对象数组模拟一个拥有10个职工的单位。
以下是日期类和员工类的实现
Program:按照如下要求设计类: (1)设计一个日期类,用于记录年、月、日,并提供对日期处理的常用方法。 (2)设计一个职工类,该职工类至少具有下面的属性:职工号,姓名,性别,生日,工作部门,参加工作时间,设计相应的方法。 (3)设计一个测试类,采用对象数组模拟一个拥有10个职工的单位。 以下是日期类和员工类的实现 /* * Description:定义日期时间类 * * Written By:Cai * * Date Written:2017-10-09 * * * */ package entity; public class MyDate { private String year; //年 private String month; //月 private String day; //日 //定义构造方法 public MyDate() { } public MyDate(String year,String month,String day) { this.year = year; this.month = month; this.day = day; } //定义setter和getter方法 public String getYear() { return year; } public void setYear(String year) { this.year = year; } public String getMonth() { return month; } public void setMonth(String month) { this.month = month; } public String getDay() { return day; } public void setDay(String day) { this.day = day; } //覆写toString()方法 public String toString() { return this.year + "年" + this.month + "月" + this.day + "日"; } }

下面是测试类
1 /* 2 * Description:定义测试类,模拟十个职工的单位 3 * 4 * Written By:Cai 5 * 6 * Date Written:2017-10-09 7 * 8 * */ 9 10 package main; 11 12 import entity.*; 13 14 public class TestDemo { 15 16 public static void main(String args[]) { 17 18 Worker[] workers = new Worker[10]; //声明Worker类数组对象,大小为10 19 20 //为数组对象依次赋值 21 for( int i = 0; i < 10; i++ ) { 22 23 workers[i] = new Worker("00000" + i,"worker_" + i,"男","办公室" + i,new MyDate("2017","10",(i + 1) + "" ),new MyDate("2017","11","" + (i + 1) )); 24 } 25 26 //打印数组对象 27 display(workers); 28 29 } 30 31 //定义方法,打印Worker类的数组对象信息 32 public static void display(Worker[] workers) { 33 34 for( int i = 0; i < workers.length; i++ ) { 35 System.out.println( workers[i] ); 36 } 37 } 38 39 }
