java+io+swing实现学生信息管理系统
本文实例为大家分享了java+io+swing实现学生信息管理系统的具体代码,供大家参考,具体内容如下
说明:
1.开发环境基于eclipse外加windowbuilder插件。
2.采用io流持续储存文件到本地磁盘。
3.Arrylist对文件信息进行操作。
一、界面展示
本地储存学生信息的txt文件,可在此对学生信息增删改查但需要注意格式。
二、项目构架
三、相关代码及介绍
1.IO部分
学生实体类
package stuManager; public class StuInfo { private int stuId;// 学号 private String stuName;// 姓名 private int stuAge;// 年龄 private String stuPrefession;// 专业 private int stuHomeNumber;// 宿舍 // Alt+Shift+S快速创建构造方法: public StuInfo() { } public StuInfo(int stuId, String stuName, int stuAge, String stuPrefession, int stuHomeNumber) { this.stuId = stuId; this.stuName = stuName; this.stuAge = stuAge; this.stuPrefession = stuPrefession; this.stuHomeNumber = stuHomeNumber; } public int getStuId() { return stuId; } public void setStuId(int stuId) { this.stuId = stuId; } public String getStuName() { return stuName; } public void setStuName(String stuName) { this.stuName = stuName; } public int getStuAge() { return stuAge; } public void setStuAge(int stuAge) { this.stuAge = stuAge; } public String getStuPrefession() { return stuPrefession; } public void setStuPrefession(String stuPrefession) { this.stuPrefession = stuPrefession; } public int getStuHomeNumber() { return stuHomeNumber; } public void setStuHomeNumber(int stuHomeNumber) { this.stuHomeNumber = stuHomeNumber; } }
学生信息写入本地磁盘txt文件类
package stuManager; import java.io.BufferedWriter; import java.io.FileWriter; import java.io.IOException; import java.util.ArrayList; import stuView.StuManagerFrm; public class ArrayListToFile { public static void main(String[] args) throws IOException { // 创建输出缓冲流对象 BufferedWriter bw = new BufferedWriter(new FileWriter("e://a.txt")); for (int i = 0; i < StuManagerFrm.list.size(); i++) { //向txt文件中写入 bw.write(StuManagerFrm.list.get(i).getStuId() + "," + StuManagerFrm.list.get(i).getStuName() + "," + StuManagerFrm.list.get(i).getStuAge() + "," + StuManagerFrm.list.get(i).getStuPrefession() + "," + StuManagerFrm.list.get(i).getStuHomeNumber()); bw.newLine(); bw.flush(); } // 释放资源 bw.close(); } }
读取本地磁盘txt文件信息类
package stuManager; import java.io.BufferedReader; import java.io.FileNotFoundException; import java.io.FileReader; import java.io.IOException; import java.util.ArrayList; import stuView.StuAdd; import stuView.StuManagerFrm; public class FileToArrayList { public static boolean a = true; public static void main(String[] args) throws IOException { // 创建一个输入缓冲对象 BufferedReader br = new BufferedReader(new FileReader("e:\\a.txt")); String line; while ((line = br.readLine()) != null) { // br.read.line读一行 String[] strArray = line.split(","); StuInfo stu = new StuInfo(); stu.setStuId(Integer.parseInt(strArray[0])); stu.setStuName(strArray[1]); stu.setStuAge(Integer.parseInt(strArray[2])); stu.setStuPrefession(strArray[3]); stu.setStuHomeNumber(Integer.parseInt(strArray[4])); StuManagerFrm.list.add(stu); } // 释放资源 br.close(); } }
删除txt文件所有信息类
package stuManager; import java.io.*; public class ClearFile { //清空文件内容 public static void clearInfoForFile(String fileName) { File file = new File("e:\\a.txt"); try { if (!file.exists()) { file.createNewFile(); } FileWriter fileWriter = new FileWriter(file); fileWriter.write(""); fileWriter.flush(); fileWriter.close(); } catch (IOException e) { e.printStackTrace(); } } }
2.Arrylist及窗口部分

总结
1.增删改查的基本操作都能正常完成。
2.对于窗口界面部分的开发运用eclipse插件WindowBuilder对项目效果上有了很大的帮助,使得可以自由设计自己想要的界面。
3.设计框架不够清晰,部分学生信息操作在监听内完成。
4.没有采用数据库存储数据而是通过io流在本地完成对文件的存储。
改进点:
1.采用MVC设计方式完成本项目。
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持我们。
