package menu;

import java.awt.BorderLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener;

import javax.swing.*;

import model.Student; import dao.StudentDao; public class Delet_Menu {

Student delet_student; JFrame delet_menu; JPanel p1,p2; JLabel l1; JTextField text; JTextArea show;

JButton delet_ok,delet_find,delet_cancel;

public void student_delet(){

delet_menu = new JFrame(\学生信息删除\p1 = new JPanel(); p2 = new JPanel();

l1 = new JLabel(\学号：\text = new JTextField(16); show = new JTextArea(100,100); delet_ok = new JButton(\删除\delet_find = new JButton(\搜索\delet_cancel = new JButton(\取消\delet_ok.setEnabled(false);

delet_cancel.addActionListener(new Monitor2()); delet_find.addActionListener(new Monitor2()); delet_ok.addActionListener(new Monitor2()); delet_menu.add(p1,BorderLayout.NORTH); delet_menu.add(show,BorderLayout.CENTER); delet_menu.add(p2,BorderLayout.SOUTH); p1.add(l1); p1.add(text); p2.add(delet_find); p2.add(delet_ok); p2.add(delet_cancel);

if(e.getActionCommand().equals(\搜索\

delet_student = new

StudentDao().findOne(Integer.parseInt(text.getText()));

if(delet_student.getName()!= null) {

String str = \找到学生 姓名：\\

show.setText(\ show.insert(str, 1); delet_ok.setEnabled(true); }

else{

show.setText(\

show.insert(\学生信息未找到\

}

if(e.getActionCommand().equals(\删除\ new StudentDao().deleteInfo(delet_student); show.setText(\

九、 修改功能（Change_Mene.java）

package menu;

import java.awt.BorderLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener;

import javax.swing.*;

import dao.StudentDao; import model.Student; public class Change_Menu {

Student change_student; JFrame change_menu; JPanel p1,p2; JLabel l1; JTextField text; JTextArea show;

JButton delet_change,delet_find,delet_cancel;

public void student_change(){

change_menu = new JFrame(\学生信息修改\p1 = new JPanel(); p2 = new JPanel();

l1 = new JLabel(\学号：\text = new JTextField(16); show = new JTextArea(100,100); delet_change = new JButton(\修改\delet_find = new JButton(\搜索\delet_cancel = new JButton(\取消\delet_change.setEnabled(false);

delet_cancel.addActionListener(new Monitor2()); delet_find.addActionListener(new Monitor2()); delet_change.addActionListener(new Monitor2()); change_menu.add(p1,BorderLayout.NORTH); change_menu.add(show,BorderLayout.CENTER); change_menu.add(p2,BorderLayout.SOUTH); p1.add(l1); p1.add(text); p2.add(delet_find); p2.add(delet_change); p2.add(delet_cancel);
