学生信息管理系统代码java_Java实现一个简单的学生信息管理系统

‘壹’ java实现一个简单的学生信息管理系统

看了你的需求,其实除了java,你还可以用易查分来做查询管理系统呢!通过易查分不用写代码,上传个excel表格就可以生成,超级简单的!

怎么给你？已经做好了！！

Student.java代码如下：

publicclassStudent{
//学号
privateStringxh;
//姓名
privateStringname;
//性别
privateStringsex;
//成绩
privatedoublecj;
//读取学号的方法
publicStringgetXh(){
returnxh;
}
//设置学号的方法
publicvoidsetXh(Stringxh){
this.xh=xh;
}
//获取姓名的方法
publicStringgetName(){
returnname;
}
//设置名字的方法
publicvoidsetName(Stringname){
this.name=name;
}
//获取性别的方法
publicStringgetSex(){
returnsex;
}
//设置性别的方法
publicvoidsetSex(Stringsex){
this.sex=sex;
}
获取成绩的方法
publicdoublegetCj(){
returncj;
}
//设置成绩的方法
publicvoidsetCj(doublecj){

}

publicvoidshowMe(){
System.out.println("姓名为"+name+"

‘陆’ Java实现简易学生信息管理系统

使用JFileChooser来选择打开文件，使用FileInputStream进行读取文件，FileOutputStream来写文件这些没什么难度吧。中间的显示，你就直接用JFileArea就是了，然后设置为自动换行。
