用java编写学生信息管理系统

1、用java编写学生信息管理系统import .*;importimport .*;import .*;import .*;class Student implementsString number,name,specialty,grade,borth,sex;public Student();public void setNumber(String number) =number;public String getNumber() return number;public void setName(String name) =name;public String getName() retur

2、n name;public void setSex(String sex) =sex;public String getSex() return sex;public void setSpecialty(String specialty) =specialty;public String getSpecialty() return specialty;public void setGrade(String grade) =grade;public String getGrade() return grade;public void setBorth(String borth) =borth;p

3、ublic String getBorth() return borth;public class StudentManager extends JFrameJLabel lb=new JLabel。录入请先输入记录，查询、删除请先输入学号，修改是对查询"+”内容改后的保存！")；static JTextField Jnumber,Jname,Jspecialty,Jgrade,Jborth;static JRadioButton boy,girl;static ButtonGroup group=null;static JButton Login,select,delet

4、e,update,show;static JPanel p1,p2,p3,p4,p5,p6,pv,ph;static Student student=null;static Hashtable Shashtable=null;static File file=null;static FileInputStream inOne=null;static ObjectInputStream inTwo=null;static FileOutputStream outOne=null;static ObjectOutputStream outTwo=null;public StudentManager

5、()super("学生基本信息管理系统");Jnumber=new JTextField(10);Jname =new JTextField(10);Jspecialty=new JTextField(10);Jgrade=new JTextField(10);Jborth=new JTextField(10); group=new ButtonGroup(); boy=new JRadioButton(" 男 ",true); girl=new JRadioButton(" 女 ",false); (boy);(girl);Logi

6、n=new JButton("录入"); select=new JButton(" 查询");delete=new JButton(" 删除");update=new JButton(" 修改 "); show=new JButton(" 显示 "); (new InputAct();(new InquestAct();(new ModifyAct();(new DeleteAct();(new ShowAct();(false);p1=new JPanel();(new JLabel(&quo

7、t;学号:",)； (Jnumber);p2=new JPanel();(new JLabel("姓名:",);(Jname);p3=new JPanel();(new JLabel("性另 k",);(boy);(girl);p4=new JPanel();(new JLabel("专业:",); (Jspecialty);p5=new JPanel();(new JLabel("年级:",);(Jgrade);p6=new JPanel();(new JLabel("出生:",);

8、(Jborth);pv=new JPanel();(new GridLayout(6,1);(p1);(p2);(p3);(p4);(p5);(p6);ph=new JPanel();(Login);(select);(update);(delete);(show);file=new File(" 学生信息.txt");Shashtable=new Hashtable();if(!()tryFileOutputStream out=new FileOutputStream(file);ObjectOutputStream objectOut=new ObjectOutput

9、Stream(out);(Shashtable);();();catch(IOException e)Container con=getContentPane();(new BorderLayout();(lb, ;(pv, ;(ph, ;setDefaultCloseOperation(EXIT_ON_CLOSE);setBounds(100,100,600,300);setVisible(true);public static void main(String args) new StudentManager();class InputAct implements ActionListen

10、erpublic void actionPerformed(ActionEvent e)(false);String number=""number=();if()>0)tryinOne=new FileInputStream(file);inTwo=new ObjectInputStream(inOne);Shashtable=(Hashtable)();();();catch(Exception ee)" 创建散列表出现问题！");if(number)String warning="该生信息已存在，请到修改页面修改!(null,war

11、ning," 警告 ",quals("男")(true); else(true); else (false);String warning=" 该学号不存在！"(null,warning,警告 ,; else (false);String warning=" 必须输入学号！"(null,warning,警告 ,;class ModifyAct implements ActionListener public void actionPerformed(ActionEvent e)String number=();St

12、ring name=();String specialty=();String grade=();String borth=();String sex=null;if()sex=();elsesex=();Student 学生 =new Student();学生.setNumber(number);学生.setName(name);学生.setSpecialty(specialty);学生.setGrade(grade);学生.setBorth(borth);学生.setSex(sex);tryoutOne=new FileOutputStream(file);outTwo=new Objec

13、tOutputStream(outOne);(number, 学生 );(Shashtable);();();(null);(null);(null);(null);(null); catch(Exception ee) "录入修改出现异常!");(false);class DeleteAct implements ActionListener public void actionPerformed(ActionEvent e) (false);String number=();if()>0) try inOne=new FileInputStream(file);

14、inTwo=new ObjectInputStream(inOne);Shashtable=(Hashtable)();();();catch(Exception ee) if(number)Student stu=(Student)(number);();();();();if().equals("男")(true);else(true);String m="确定要删除该学生的记录吗？'int ok=(null,m," 确认 ",;if(ok=(number); tryoutOne=new FileOutputStream(file)

15、;outTwo=new ObjectOutputStream(outOne);(Shashtable);();();(null);(null);(null);(null);(null);catch(Exception ee)else if(ok=(null);(null);(null);(null);(null);elseString warning=" 该学号不存在！"(null,warning,警告 ,; elseString warning=" 必须输入学号！"(null,warning,警告 ,;class ShowAct implements

16、ActionListenerpublic void actionPerformed(ActionEvent e) new StudentShow(file);class StudentShow extends JDialogHashtable 学生散列表= null;JTextArea 显示 =null;FileInputStream inOne=null;ObjectInputStream inTwo=null;File file=null;public StudentShow(File file)super(new JFrame(),”显示对话框");=file;显示 =new

17、JTextArea(16,30);tryinOne=new FileInputStream(file);inTwo=new ObjectInputStream(inOne);学生散列表=(Hashtable)();();();catch(Exception ee)if(学生散列表.isEmpty()显示.append("目前还没有学生的信息记录！n");else显示.setText("学号姓名性别专业年级出生n");for(Enumeration enm= 学生散列表.elements();();)Student stu=(Student)();String sex=""if().equals("男")sex="男"else sex="女"；String str=()+","+()+","+sex+","+()+","+()+","+
