Loop for console input....

[Jonathan King]

All right guys and gals, I've been working on this for hours now, and I am stuck!! I get a user's choice from console, and perform some actions based on that choice. After, they can enter 'y' to try another menu choice, or any key to exit the program. I have gotten to where the program runs great, and when they choose y to try again, the menu will print, and they can do another choice, but if I want to choose 'y' again, it just ends. I would like to get it to loop so if they press 'y' 1000 times after running a choice (as long as it is not the exit choice) it will print the menu again and they can choose another choise. HOW!!! PLEASE EASE MY FRAZZLED MIND!!! ARGGGHHHH!!!

import java.io.*;
public class BridgeHandTest
{
 public static void main(String[] args)
{
BufferedReader console = new BufferedReader(new InputStreamReader(System.in));
String filename = "";
int filenumber = 0;
boolean done = false;
try
{
while(done == false)
{
do
{
System.out.println("1. BridgeHand.txt");
System.out.println("2. BridgeHand2.txt");
System.out.println("3. BridgeHand3.txt");
System.out.println("4. Exit");
System.out.println("Please enter the number which corresponds to the Bridge hand you would like to see: ");
String input = "";
input = console.readLine();
filenumber = Integer.parseInt(input);

switch(filenumber)
{
case 1: filename = "BridgeHand.txt"; done=true; break;
case 2: filename = "BridgeHand2.txt"; break;
case 3: filename = "BridgeHand3.txt"; break;
case 4: System.exit(0);
default: System.out.println("Invalid option.  Please try again: "); break;
}

}while(filenumber > 4);

BridgeHand yourBridgeHand = new BridgeHand();
yourBridgeHand.readFile(filename);
//yourBridgeHand.getPointsSuit();
//yourBridgeHand.getPointsRank();
System.out.print("Total points for this hand = ");
System.out.println(yourBridgeHand.getPointsSuit() + yourBridgeHand.getPointsRank());

System.out.println("Press 'Y' to try another, any other key to quit.");
String input = "";
input = console.readLine();

if(input == "Y" || input == "y")
{
done=false;
}

}
}
catch(IOException exception)
{
System.out.println("Input error " + exception);
}
if(!done)
{
System.out.println("File not found!");
done = true;
}

System.exit(0);
}
}

THANK YOU!!!

Your if condition where you check if input is y is the problem. The var input is a String; Strings cannot be compared via the == operator. Look at the String documentation in the API to see what method you need to use.
I noticed that you are setting done = true outside the while loop.
