学生信息系统java课程设计.doc

Java组件实验报告 班级：110612 学号：110612112 专业：网络工程 姓名：xxxxxxx实验目的：1、 掌握java图形用户界面设计常用类及其各自重要方法的应用。2、掌握java事件处理模式并熟练掌握lable事件单选框和复选框处理的方法。3、 进一步掌握javaAWT组件、Swing组件及事件编程的各种方法。掌握事件监听和事件处理方法。实验内容：1. 编辑一个简单的学生信息系统。2. 要求第一行是姓名输入框。3. 第二行利用单选框来设置男女。4. 第三行是用复选框来设置四门课程。5. 最后需要把所有的学生信息输出。实验代码：import java.awt.*;import java.awt.event.*;import java.util.ArrayList;import java.util.Collection;import java.util.HashMap;import java.util.Iterator;import java.util.Map;import javax.swing.*;import javax.swing.border.*;public class StudentManagerJFrame frame = new JFrame (选课系统);JCheckBox jcb_en = new JCheckBox(英语);JCheckBox jcb_math = new JCheckBox(高数);JCheckBox jcb_sport = new JCheckBox(体育);JCheckBox jcb_physics = new JCheckBox(大物);JLabel jl_name=new JLabel(姓名：);JTextField jtb_name=new JTextField();JRadioButton jrb_male = new JRadioButton(男);JRadioButton jrb_female = new JRadioButton(女);private Map classes=new HashMap();JTextArea ta = new JTextArea(); /resultpublic static void main(String args)StudentManager ts = new StudentManager();ts.go();private String getClasses()if(null=classes|classes.size()1)return null;elseStringBuilder sb=new StringBuilder();Collection values=classes.values();Iterator it=values.iterator();while(it.hasNext()sb.append(it.next()+、);return 选的课程为：+sb.toString().substring(0,sb.length()-1)+。;public void go()JPanel jp_name = new JPanel();JPanel jp_sex=new JPanel();JPanel pa = new JPanel();JPanel pb = new JPanel();Border etched = BorderFactory.createEtchedBorder();jtb_name.setPreferredSize(new Dimension(100,30);jp_name.add(jl_name);jp_name.add(jtb_name);ButtonGroup bg_sex = new ButtonGroup();bg_sex.add(jrb_male);bg_sex.add(jrb_female);jrb_male.setSelected(true);jp_sex.add(jrb_male);jp_sex.add(jrb_female);Border border=BorderFactory.createTitledBorder(etched,性别);jp_sex.setBorder(border);pa.add(jcb_math);pa.add(jcb_en);pa.add(jcb_physics);pa.add(jcb_sport);pa.setLayout(new GridLayout(1,0);border= BorderFactory.createTitledBorder(etched, 课程 );pa.setBorder(border); ItemListener il = new ItemListener()public void itemStateChanged(ItemEvent e)JCheckBox cb = (JCheckBox) e.getSource();if (cb = jcb_math)if(jcb_math.isSelected()classes.put(math, jcb_math.getText();elseclasses.remove(math); else if (cb = jcb_en)if(jcb_en.isSelected()classes.put(en, jcb_en.getText();elseclasses.remove(en); else if (cb = jcb_physics)if(jcb_physics.isSelected()classes.put(physics, jcb_physics.getText();elseclasses.remove(physics); else if (cb = jcb_sport)if(jcb_sport.isSelected()classes.put(sport, jcb_sport.getText();elseclasses.remove(sport); getResult();private void getResult() StringBuilder sb=new StringBuilder();sb.append(jl_name.getText()+jtb_name.getText()+System.lineSeparator();sb.append(性别：);if(jrb_male.isSelected()sb.append(jrb_male.getText();elsesb.append(jrb_female.getText();sb.append(System.lineSeparator();sb.append(getClasses();ta.setText(sb.toString();jcb_math.addItemListener(il);jcb_en.addItemListener(il);jcb_physics.addItemListener(il);jcb_sport.addItemListener(il);pb.setLayout(new GridLayout(0,1);pb.add(ta);Container cp = frame.getContentPane();cp.setLayout(new GridLayout(0,1);cp.add(jp_name);cp.add(jp_sex);cp.add(pa);cp.add(pb);frame.setResizable(false);frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
