Java点击button事件问题！求救！

Question

编写一个小程序，类似选房间的，一共5个button，每点一个会出现一个新的frame，每个frame就是一个房间，每个房间是一样的，只有房间号码不一样， 程序如下，两个类：
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;

public class Test extends JFrame implements ActionListener{

JButton buttonRoom;
static RunTest room[] = new RunTest[5];
static int[] roomID = {1,2,3,4,5};
public static void main(String args[]) {
new Test().launchFrame();
}

public void launchFrame() {
setSize(300, 200);
this.setTitle("choose room");
setLocation(400, 300);
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
setLayout(new FlowLayout());
setVisible(true);

for (int i = 0; i < roomID.length; i++) {
buttonRoom = new JButton("Room" + i);
room[i] = new RunTest(roomID[i]);
add(buttonRoom);
}
buttonRoom.addActionListener(this);
}

public void actionPerformed(ActionEvent e) {
if(e.getSource()==buttonRoom){
switch(5){
case 1:
room[1] = new RunTest(roomID[1]);
case 2:
room[2] = new RunTest(roomID[2]);
case 3:
room[3] = new RunTest(roomID[3]);
case 4:
room[4] = new RunTest(roomID[4]);
case 5:
room[5] = new RunTest(roomID[5]);
}

}
}
}
import javax.swing.JFrame;

public class RunTest extends JFrame {
int roomID;

public RunTest(int roomID){
this.roomID = roomID;
}
public void setRoomID(int roomID){
this.roomID = roomID;
}
public int getRoomID(){
return roomID;
}
public void room() {
setSize(300, 200);
this.setTitle("room X");
setLocation(400, 300);
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
setLayout(null);
setVisible(true);
}
}

写的不对，谁帮我改改啊，思路是用for loop 在JFrame里循环加入5个按钮，每点一个按钮就出现一个房间，房间时一样的，所以不想写5个房间，写一个应该就能表示了， 每个房间有个id，请求大侠们帮小弟改改 小弟感激不尽 谢谢！

已改好：如下
下面是Test .java
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;

import javax.swing.JButton;
import javax.swing.JFrame;

public class Test extends JFrame implements ActionListener{

JButton buttonRoom;
static RunTest room[] = new RunTest[5];
static int[] roomID = {1,2,3,4,5};
public static void main(String args[]) {
new Test().launchFrame();
}

public void launchFrame() {
setSize(300, 200);
this.setTitle("choose room");
setLocation(200, 300);
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
setLayout(new FlowLayout());
setVisible(true);

for (int i = 0; i < roomID.length; i++) {
buttonRoom = new JButton( i+"");
room[i] = new RunTest(roomID[i]);
add(buttonRoom);
buttonRoom.addActionListener(this);
}

}

public void actionPerformed(ActionEvent e) {

System.out.println("sss"+ e.getActionCommand());
int a=Integer.parseInt(e.getActionCommand());

// room[0] = new RunTest(a+1); 这是我自己写的，我觉得也行，下面是在你的基础上修改的
// room[0].room();

switch(a){
case 1:
room[0] = new RunTest(roomID[1]);room[0].room();break;
case 2:
room[1] = new RunTest(roomID[2]);room[1].room();break;
case 3:
room[2] = new RunTest(roomID[3]);room[2].room();break;
case 4:
room[3] = new RunTest(roomID[4]);room[3].room();break;
case 5:
room[4] = new RunTest(roomID[5]);room[4].room();break;
}

}

}

-----------------------------------------------------------------------------------------------------------
以下是RunTest .java
import javax.swing.JFrame;

public class RunTest extends JFrame {
int roomID;

public RunTest(int roomID){
this.roomID = roomID;
}
public void setRoomID(int roomID){
this.roomID = roomID;
}
public int getRoomID(){
return roomID;
}
public void room() {
setSize(400, 300);
this.setTitle("room"+roomID);
setLocation(600+roomID*4, 300+roomID*6);
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
setLayout(null);
setVisible(true);
}
}

提醒两点，一是switch case用法后要加break；二是数组的坐标是从0开始的
