2.个人负责模块或任务说明

负责person类的编写，建立person对象，
完成Menu中增删改查的功能。

3.自己的代码提交记录截图

4..自己负责模块或任务详细说明

1、建立对象建立可序列化对象person，并构建函数。

主要代码：
import java.io.Serializable;
public class Person implements Serializable{
    private String num;
	private String name;
	private String dor;
        private String address;
        private String sex;
        private String date;
    private String pol;
    private String phone;
	public Person(){}
	public Person(String num,String name,String dor,String address,String sex,String date,String pol,String phone ){
		this.num=num;
		this.name=name;
                this.dor=dor;
		this.address=address;
                this.sex=sex;
                this.date=date;
                this.pol=pol;
            this.phone=phone;
    }
    public void setNum(String num){
		this.num=num;
	}
	public String getNum(){
		return num;
	}
	public void setName(String name){
		this.name=name;
	}
	public String getName(){
		return name;
	}
	public void setDor(String dor){
		this.dor=dor;
	}
	public String getDor(){
		return dor;
	}
	public void setAddress(String address){
		this.address=address;
	}
	public String getAddress(){
		return address;
	}
	public void setSex(String sex){
		this.sex=sex;
	}
	public String getSex(){
		return sex;
	}
	public void setDate(String date){
		this.date=date;
	}
	public String getDate(){
		return date;
	}
	public void setPol(String pol){
		this.pol=pol;
	}
	public String getPol(){
		return pol;
	}
	public void setPhone(String phone){
		this.phone=phone;
	}
	public String getPhone(){
		return phone;
	}       

}

2.增加学生信息功能
but1.addActionListener(new ActionListener() { // 增加，内部类//进行某项操作时触发功能
		public void actionPerformed(ActionEvent e) {//用于接收操作事件的侦听器接口
				if (e.getSource() == but1) {
					but3.setEnabled(false);//使but3这个按钮变灰不可点击了
					String number1 = number.getText();
					if (number1.length() == 12) {
						try {
							ObjectInputStream in = new ObjectInputStream(new FileInputStream(file));//读回对象
							has = (Hashtable) in.readObject();							                       in.close();
						} catch (Exception e1) {
						}
                 					} else {
						JOptionPane.showMessageDialog(null, "请输入12位数字的学号");//提示框显示
					}
					//
					if (number1.length() == 12) {
					if (has.containsKey(number1)) {						JOptionPane.showMessageDialog(null, "该生信息已存在，请到修改页面修改！");
					} else {
						String name1 = name.getText();
						String dor1 = dor.getText();
						String address1 = address.getText();
						String sex1 = sex.getText();
						String date1 = date.getText();
						String pol1 = pol.getText();
						String phone1 = phone.getText();
						Person per = null;
						per = new Person(number1, name1, dor1, address1, sex1, date1, pol1, phone1);
						has.put(number1, per);// ???
						try {
							ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream(file));
							out.writeObject(has);
							out.close();
                       JOptionPane.showMessageDialog(null, "添加成功！");
						} catch (Exception e1) {}
					}
					}
				}
			}

3.）修改功能：为了防止误修改，首先要查看，才能修改，查看后直接改输入栏中的数据，点击修改，既修改成功。
but3.addActionListener(new ActionListener() { // 修改
		public void actionPerformed(ActionEvent e) {

				if (e.getSource() == but3) {
					but3.setEnabled(false);
					String number1 = number.getText();
					String name1 = name.getText();
					String dor1 = dor.getText();
					String address1 = address.getText();
					String sex1 = sex.getText();
					String date1 = date.getText();
					String pol1 = pol.getText();
					String phone1 = phone.getText();
					Person per = new Person(number1, name1, dor1, address1, sex1, date1, pol1, phone1);
					has.put(number1, per);
					JOptionPane.showMessageDialog(null, "修改成功");
					try {
						ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream(file));
						out.writeObject(has);
						out.close();
					} catch (Exception e1) {
					}
				}
			}
		});

4.查看功能：首先输入要查看的学号，点查看，信息将会显示在输入栏中。如果学号不存在，下面会有提示。
but4.addActionListener(new ActionListener() { // 查看
		public void actionPerformed(ActionEvent e) {

				if (e.getSource() == but4) {
					but3.setEnabled(false);
					String number1 = number.getText();
					if (number1.length() == 12) {
						if (has.containsKey(number1)) {
							try {
								ObjectInputStream in = new ObjectInputStream(new FileInputStream(file));
								has = (Hashtable) in.readObject();
								in.close();
							} catch (Exception e1) {
							}
							Person per = (Person) has.get(number1);
							name.setText(per.getName());
							dor.setText(per.getDor());
							address.setText(per.getAddress());
							sex.setText(per.getSex());
							date.setText(per.getDate());
							pol.setText(per.getPol());
							phone.setText(per.getPhone());

							but3.setEnabled(true);
						} else {
							JOptionPane.showMessageDialog(null, "学号不存在");
						}
					} else {
						JOptionPane.showMessageDialog(null, "请输入12位数字的学号");
					}
				}
			}

		});
5.（5）删除功能：先输入要删除的学号，点删除，该学生的信息将被移除，在查看该学号，将不存在。
but2.addActionListener(new ActionListener() { // 删除
    		public void actionPerformed(ActionEvent e) {
				if (e.getSource() == but2) {
					but3.setEnabled(false);
					String number1 = number.getText();
					if (number1.length() == 12) {
						try {
							ObjectInputStream in = new ObjectInputStream(new FileInputStream(file));
							has = (Hashtable) in.readObject();
							in.close();
						} catch (Exception e1) {
						}
					} else {
						JOptionPane.showMessageDialog(null, "请输入12位数字的学号");
					}
					if (has.containsKey(number1)) {
						has.remove(number1);
						ObjectOutputStream out = null;
						JOptionPane.showMessageDialog(null, "删除成功");
						try {
							out = new ObjectOutputStream(new FileOutputStream(file));
							//out.writeObject(has);
							out.close();
						} catch (IOException ex) {
							Logger.getLogger(Menu.class.getName()).log(Level.SEVERE, null, ex);//记录当前类可能发生的异常
						}
					} else {
						JOptionPane.showMessageDialog(null, "学号不存在");
					}
				}
			}
		});

5.五.课程设计感想

我们打算做文本io时想实现内存与文本的交互一直无法成功，后来百度查了一下是需要将数据可序列化才能行，而且还要用ObjectOutputStream和ObjectInputStream来传递数据，而它们对象序列话是在它们中实现的，这些我们都没学过。还好书上有，网上也有它们的解析，于是我们就一点一点的尝试，最终实现内存与文本的交互并把数据存到文本里。
