Hello all, I have to hand in this assingment at 6:00 a.m. and I was just wondering why after you enter a 0-5 the program does what its supposed to, then loops 2 more times without waiting for the user to enter a number or letter... here is the code, it should run for you...
import java.io.*;
public class Counter2 {
public static void main( String[] args )
throws java.io.IOException
{
int Main = 0;
int All = 0;
char selection;
System.out.println("Welcome to Dustin McCulloch''s Bingo Program!");
System.out.println(" ");
do {
int i = 0;
System.out.println("Press the number 0-5 for the equivalent verse, press a for all, and q to quit");
System.out.flush();
selection = (char) System.in.read();
if (selection == ''a''){
Main = 20;
All = 6;
}
if (selection == ''5''){
Main = 10;
}
if (selection == ''4''){
Main = 5;
}
if (selection == ''3''){
Main = 4;
}
if (selection == ''2''){
Main = 3;
}
if (selection == ''1''){
Main = 2;
}
if (selection == ''0''){
Main = 1;
}
if (selection == ''q''){
Main = 0;
}
System.out.println(" ");
if (selection != ''q''){
System.out.println("Farmer Brown, he had a dog and Bingo was his name. Oh!");
while ( i < 3 ) {
i++;
if (selection == ''0''){
System.out.println("B "+ "I " +"N "+ "G "+ "O");
}
if (selection == ''1''){
System.out.println(" "+ "I "+ "N "+ "G "+ "O");
}
if (selection == ''2''){
System.out.println(" "+ " "+ "N "+ "G "+ "O");
}
if (selection == ''3''){
System.out.println(" "+ " "+ " "+ "G "+ "O");
}
if (selection == ''4''){
System.out.println(" "+ " "+ " "+ " "+ "O");
}
if (selection == ''5''){
System.out.println(" "+ " "+ " "+ " "+ " ");
}
}
System.out.println("and Bingo was his name. Oh.");
}
} while (selection != ''q'');
}
}
I believe that System.in.read() will only read in a single byte, so you''re getting the 5,
then the carriage return, then the linefeed
(assuming you''re running a WinTel system)
If you want to read just an integer, you need to read in a string, then call Integer.parseInt(s);
Hope this helps

I have heard someone talk about that in class, yes, it makes sense that it also reads the carriage return, where do I put that code you offered???
