java学生信息管理系统
原首 人气:0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();
}
}

}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。
