GCD java code - jroh97 - Sep 29, 2014

Here is my code.

import java.util.*;
public class GCD
{
public static void main (String args [] )
{
Scanner reader = new Scanner(System.in);
int a, b, x, d = 0, c = 0;
String response;
do
{
System.out.println("Please enter first number to find GCD.");
a = reader.nextInt();
System.out.println("Please enter second number to find GCD.");
b = reader.nextInt();

for (x = a-1; x>=1; x--)
{
c = a%x;
if (c==0)
{
d = b%x;
if (d==c)
{
break;
}
}
}

System.out.println(x);

System.out.println("Would you like to go again?");
response = reader.nextLine();
response = reader.nextLine();
}while ( response.equals("yes") );

System.out.println("Have a nice day.");
}
}

Why doesn't it work. We haven't learned the methods so we have to use loops. Can anyone help me out?

What do you mean it "doesn't work"?

I think you should fix this for some reason...it's like a pet peeve.

Code 
while ( response.equals("yes"));

I'd make that ignorecaps...or...

Code 
response = reader.nextLine().toLowerCase();

That way instead of

Code 
Would you like to go again?

Have a nice day.

It does...

Code 
Would you like to go again?

Please enter first number to find GCD.
