*********H E L P*********with SWITCH STATEMENT

Question

I am creating a class that extends object. I am using JOptionPane for input. I have a switch statement that I am using to call other methods, such as displaying a flag using GraphicsPen. Everything works great except when the switch calls the flag method and displays the flag, I can't close the flag until I end the switch method. I have a " for(;;) " statement that encloses the main method so the switch method will continue after each iteration.*********HELP*********PLEASE!*****************

class switchflags extends Object //class declaration
public static void main (String[]args) //main method
final String TITLE = "SWITCH"; //title for dialogs
for (;;) //loop
String switchstring = JOptionPane.showInputDialog //dialog for input
(null,"Select which program you want to use from below.\n\n"+
"*******Press enter when finished*******\n\n"+
"Enter 0 : to Quit\n"+
"Enter 1 : to see the Dutch Flag\n"+
"Enter 2 : to see the Mauritius Flag\n"+
"Enter 3 : to see the Italian Flag\n"+
"Enter 4 : to see the Norwegian Flag\n"+
"Enter 5 : to calculate Fibonacci number (n)\n"+
"Enter 6 : to calculate Miles Per Gallon\n\n",TITLE,JOptionPane.INFORMATION_MESSAGE);
int switchint = Integer.parseInt(switchstring); //convert string to a integer
if (switchint == 0) //exit if 0 was entered
JOptionPane.showMessageDialog
(null,"Thanks for using this program.\nHave a nice day!",TITLE,JOptionPane.PLAIN_MESSAGE);
System.exit(0); //end program
else if (switchint < 0) //show error for invalid numbers less than zero
JOptionPane.showMessageDialog
(null,"*******ERROR*******\n\nEnter a number\nbetween (1 - 6).\n\nOr (0) to Quit.\n\n",
TITLE,JOptionPane.ERROR_MESSAGE);
else if (switchint > 6) //show error for invalid numbers greater than six
JOptionPane.showMessageDialog
(null,"*******ERROR*******\n\nEnter a number\nbetween (1 - 6).\n\nOr (0) to Quit.\n\n",
TITLE,JOptionPane.ERROR_MESSAGE);
switch (switchint) //test variable that was entered
case 1: DutchFlag1.start(); //display Dutch flag
break;
case 2: mauritius.start(); //display Mauritius flag
break;
case 3: italy.start(); //display Italy flag
break;
case 4: norway.start(); //display Norway flag
break;
case 5: FIBONACCI.start(); //run Fibonacci program
break;
case 6: MPG.start(); //run MPG program
break;
