您好，现在是想做一个有界面的应用程序，再利用输入输出流实现对数据的读写，从而实现对小型数据库中数据进行增删改查功能，目前界面已做好，问题是在程序怎样导入小型数据库并且实现功能。有程序示例就更好啦，非常感谢！

我做的是学生公寓信息管理系统，以下是我界面的程序，可以看一下

package gtt;

import java.awt.*;

import javax.swing.*;

import javax.swing.border.TitledBorder;

import java.awt.event.*;

import java.awt.event.*;

import java.io.*;

public class g extends JFrame{

JButton b1=new JButton();

JButton b2=new JButton();

JButton b3=new JButton();

JButton b4=new JButton();

JLabel l1=new JLabel();

JLabel l2=new JLabel();

JLabel l3=new JLabel();

JLabel l4=new JLabel();

JLabel l5=new JLabel();

JLabel l6=new JLabel();

JLabel l7=new JLabel();

JLabel l8=new JLabel();

JLabel l9=new JLabel();

JTextField t1=new JTextField(" "

+ " ");

JTextField t2=new JTextField();

JTextField t3=new JTextField(" ");

JPanel p1=new JPanel();

JPanel p2=new JPanel();

JPanel p3=new JPanel();

JPanel p4=new JPanel();

public g()

{

super("学生公寓信息管理");

setSize(500,660);

Container cp=getContentPane();

cp.setLayout(new GridLayout(2,1));

//p1.setBounds(10, 10, 460, 330);

p1.setBackground(Color. pink);

p1.setBorder(new TitledBorder("查询:"));

cp.add(p1);

p1.add(b1);

b1.setLabel("查找");

p1.add(p3);

p1.add(l4);

//p2.setBounds(10, 380, 460, 330);

p2.setBackground(Color.green);

p2.setBorder(new TitledBorder("学生公寓清单:"));

cp.add(p2);

p2.add(b2);

b2.setLabel("添加");

p2.add(b3);

b3.setLabel("删除");

p2.add(b4);

b4.setLabel("修改");

p2.add(p4);

//p4.setLayout(new GridLayout(2,1));

//p4.setBounds(10, 380, 460, 230);

//p4.add(t3);

p3.setLayout(new GridLayout(3,1));

l1.setText("楼号：");

p3.add(l1);

p3.add(t1);

l2.setText("宿舍号：");

p3.add(l2);

p3.add(t2);

l3.setText("男/女生公寓：");

p3.add(l3);

Choice ch1=new Choice();

ch1.add("男生");

ch1.add("女生");

p3.add(ch1);

//p4.setLayout(new GridLayout(1,1));

//p4.setBounds(10, 380, 460, 230);

p4.add(t3);

b1.addMouseListener(new aa());

b2.addMouseListener(new bb());

b3.addMouseListener(new cc());

b4.addMouseListener(new dd());

setVisible(true);

}

class aa extends MouseAdapter

{

public void mouseClicked(MouseEvent e)

{

l4.setText("OK!成功！");

}

}

class bb extends MouseAdapter

{

public void mouseClicked(MouseEvent e)

{

l5.setText("OK!成功！");

}

}

class cc extends MouseAdapter

{

public void mouseClicked(MouseEvent e)

{

l6.setText("OK!成功！");

}

}

class dd extends MouseAdapter

{

public void mouseClicked(MouseEvent e)

{

l7.setText("OK!成功！");

}

}

public static void main(String[] args)

{

new g();

}

}

运行之后就是这样子
