java学生信息管理系统MVC架构

一、项目结构

        学生信息管理系统分三层进行实现。student.java主要提供数据，cotroller.java的功能是绑定试图和计算数据。Stuview.java用于单一的用来显示数据。




二、源码

1.1、Student 类

/*
* @FileName: Student.class
* @version:1.0
* @author:nazi
* 描述：模型层
* */
import java.io.Serializable;

/*
* Summary: Student类实现序列化接口，用于对象的保存
* @author：nazi
* @version:1.0
* */
public class Student implements Serializable {
//序列化id
private static final long serialVersionUID = 9088453456517873574L;
int num;
String name;
String sex;
int age;
float grade;

public Student(int num ,String nameString,String sexString,int g,float f){
this.num =num;
name = nameString;
sex =sexString;
age =g;
grade =f;
}

public int getNum(){
return num;
}

public String getName(){
return name;
}

public String getSex(){
return sex;
}

public int getAge(){
return age;
}

public float getGrades(){
return grade;
}

public String toString(){
return "姓名:"+name+"学号:"+num+"性别:"+sex+"年龄:"+age+"成绩:"+grade;

}

}

1.2、Cotroller类

/*
* 文件名： Cotroller.java
* 描述：mvc中的c，用来管理模型层的数据
* @authur:Nazi
* function ：增、删、改、查、保存、更新
* */
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.util.ArrayList;
import java.util.Iterator;

/*
* Cotroller类集中对ArrayList<Student>进行操作
* @Author nazi
* @version 1.0
* */
public class Cotroller  {

//student数据集合
private  ArrayList<Student> list;

public Cotroller(ArrayList<Student> l){
this.list =l;
}

/*
* rturn a ArrayList<Student>
* */
public ArrayList<Student> getList()
{
return list;
}

/*
* 初始化Student数组
* */
public void setList(ArrayList<Student> list)
{
this.list = list;
}

/*
* add a student to the List
* */
public void add(Student s)
{
list.add(s);
}

/*
* remove the student from list
* */
public void remove(int id)
{
for(Iterator<Student> iter = list.iterator(); iter.hasNext();)
{
Student s = iter.next();

if(s.getNum() == id)
{
list.remove(s);
}
}
}

/*
* print the specific student
* */
public String  printAll(int i) {
return list.get(i).toString();
}

/*
* 功能简述：将实现序列化后的对象写入到文件中。
* 文件输出地址："/home/nazi/2.txt" 文件地址可以更改
* */
public void fileOt() throws FileNotFoundException{
FileOutputStream fo = new FileOutputStream("/home/nazi/2.txt");
try {
ObjectOutputStream so = new ObjectOutputStream(fo);
so.writeObject(list);
so.close();
} catch (IOException e) {
e.printStackTrace();
}

}

/*
* function: 从指定路径读取文件，然后将对象状态进行赋值使用
*
* */
@SuppressWarnings("unchecked")
public void fileIn() throws FileNotFoundException{
FileInputStream fi = new FileInputStream("/home/nazi/2.txt");
try {
ObjectInputStream si = new ObjectInputStream(fi);
list = (ArrayList<Student>) si.readObject();
si.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}

1.3、StuView类

/*
* FileName:StuView.class
* 描述：以特定的方式展示数据
* @Atuthor:nazi
* @version:1.0
* */
import java.awt.Font;
import java.awt.event.ActionEvent;

* */
public class StuView  {
private static Cotroller cotroller;
public static void main(String args[]){
//创建管理者
cotroller = new Cotroller(new ArrayList<Student>());
//界面
initFrame();
}

/*
* InitFrame()中含有各种类型的控件，以及控件所对应的事件处理步骤
* */

//打印
for(int i = 0;i<cotroller.getList().size();i++){
