学生管理系统（JAVA） —— 查找学生信息页面

查找页面UI界面如下，2项选择可分别跳转到相应页面：

UI界面设计如下：

package ui;

import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.Font;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.ButtonGroup;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JRadioButton;

public class Search extends JFrame implements ActionListener {
	JLabel title;
	JRadioButton number,teacher;
	JButton dft,rtn;
	JPanel sec1,sec2,sec3;

	public Search() {
		// TODO Auto-generated constructor stub
		Container con=getContentPane();
		con.setLayout(new BorderLayout());//将容器设置为边框布局
		sec1=new JPanel();
		sec2=new JPanel();
		//边框布局中嵌套一个网格布局，放置两个单选按钮
		sec2.setLayout(new GridLayout(1,2));
		sec3=new JPanel();
		title=new JLabel("学生管理系统");
		title.setFont(new Font("黑体", Font.PLAIN, 20));
		ButtonGroup bg=new ButtonGroup();
		number=new JRadioButton("1.按学号查询",true);
		teacher=new JRadioButton("2.按教师姓名查询");
		bg.add(number);
		bg.add(teacher);
		dft=new JButton("确定");
		dft.addActionListener(this);
		rtn=new JButton("返回");
		rtn.addActionListener(new ActionListener() {
			
			@Override
			public void actionPerformed(ActionEvent e) {
				// TODO Auto-generated method stub
				setVisible(false);
				new Host().setVisible(true);
			}
		});
		sec1.add(title);
		sec2.add(number);
		sec2.add(teacher);
		sec3.add(dft);
		sec3.add(rtn);
		//将3个面板分别放置在容器的north,center,south位置
		con.add(sec1,BorderLayout.NORTH);
		con.add(sec2,BorderLayout.CENTER);
		con.add(sec3,BorderLayout.SOUTH);
		setTitle("查询学生信息");
		setSize(300,150);
		setVisible(true);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	}

	@Override
	public void actionPerformed(ActionEvent e) {
		// TODO Auto-generated method stub
		if(number.isSelected()) {
			this.setVisible(false);
			new SearchByNum().setVisible(true);
		}else {
			this.setVisible(false);
			new SearchByTea().setVisible(true);
		}

	}

}

下一步：
按学号查询信息
按教师姓名查询信息
