Y do u have a .nextLine in there? just have a System.out.println(numIn);

I bet your code is halting here because its waiting for an input value.

while (numInput != number) {
 numInput = numIn.nextInt();
 }

EDIT: and it will not exit the while loop until the number you input is equal to number.

I have an value for numInput it is 0. It's at the top.

.nextLine is suppose to be there, but I would have to show you a visual for the program for it to be obvious.

The thing it is running fine. Everything is compiling. It's just not showing;

"Too low, try again"
or
"Too high, try again"


while it is running.

What exiles is saying is that:

Lets say your number is 42.
user enters 41, loop tries again
user enters 39, loop tries again
user enters 42, the condition becomes false exiting the loop.

while (numInput != number) {
 numInput = numIn.nextInt();
}

now, you check to see if the numInput is equal to number, which will always happen since you made your loop forces the value to be equal to the number.

I'm confused, why are your "else if" statements not within the while loop?

Don't you want it to run until you guess correctly? If you keep asking them for an input over and over until they get it right, then of course the statements will never be printed. Those statements need to be inside the while loop.

Wow... okay I see now. Careless error.
