Java实训第八次

上次博客我们创建了窗口界面类，但是没有将他编写完成进行到最后一步，上次博客我编写到了按系部查询窗口

创建按性别统计人数窗口CountStudentsBySexFrame

详细代码如下：

package net.lyq.student.gui;import net.lyq.student.service.StudentService;
import net.lyq.student.service.impl.StudentServiceImpl;import javax.swing.*;
import javax.swing.border.TitledBorder;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import java.awt.print.PrinterException;
import java.util.Vector;public class CountStudentsBySexFrame extends JFrame {private JPanel panel;private JPanel pnlSouth;private JPanel pnlCenter;private JButton btnPrint;private JButton btnExit;private JScrollPane scroller; // 滚动面板private Vector rows; // 记录行集private Vector<String> colHead; // 表格列标题private JTable table; // 表格private StudentService studentService; // 学生服务对象public CountStudentsBySexFrame(String title) {super(title);initGUI();}/*** 初始化用户界面*/private void initGUI() {// 创建组件panel = (JPanel) getContentPane();pnlCenter = new JPanel();pnlSouth = new JPanel();rows = new Vector();colHead = new Vector();btnPrint = new JButton("打印[P]");btnPrint.setMnemonic(KeyEvent.VK_P);btnExit = new JButton("退出[X]");btnExit.setMnemonic(KeyEvent.VK_X);// 添加组件panel.add(pnlSouth, BorderLayout.SOUTH);panel.add(pnlCenter, BorderLayout.CENTER);pnlSouth.setLayout(new FlowLayout(FlowLayout.RIGHT));pnlSouth.add(btnPrint);pnlSouth.add(btnExit);pnlCenter.setLayout(new BorderLayout());TitledBorder tb = new TitledBorder("统计结果");pnlCenter.setBorder(tb);// 创建学生服务对象studentService = new StudentServiceImpl();// 获取按性别统计结果记录行集rows = studentService.findRowsBySex();// 设置表头colHead.add("性别");colHead.add("人数");// 创建表格（参数1：记录集；参数2：表头）table = new JTable(rows, colHead);scroller = new JScrollPane(table, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);pnlCenter.add(scroller, BorderLayout.CENTER);repaint(); // 重绘窗体if (rows.isEmpty()) {JOptionPane.showMessageDialog(this, "没有记录！", "错误提示", JOptionPane.WARNING_MESSAGE);}// 设置窗口大小setSize(300, 200);// 设置窗口不可调整大小setResizable(false);// 设置窗口屏幕居中setLocationRelativeTo(null);// 设置窗口标题setTitle("按性别统计学生人数");// 设置窗口可见setVisible(true);// 设置窗口默认关闭操作（卸载当前窗口）setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);// 【退出】按钮单击事件btnExit.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent arg0) {dispose();}});// 【打印】按钮单击事件btnPrint.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {try {table.print();} catch (PrinterException e1) {e1.printStackTrace();}}});}public static void main(String[] args) {new CountStudentsBySexFrame("");}
}

运行结果：

创建按班级统计人数窗口CountStudentsByClassFrame

}
