on_off

Can someone please explain what: while(on_off==1) does

[Norm]

It compares (==) the value of the variable to the value 1. If true the statement following the while is executed.

Below is my code for a random number game.
Can I assume that while (on_off==1) simply runs the while loop until it is false-meaning the number is correctly guessed? At which point on_off=0 thus exiting the loop?


Random generator = new Random();

int number = generator.nextInt(1024) + 1;
int on_off = 1;
int guess;
String inputString;

while(on_off == 1){
inputString = JOptionPane.showInputDialog("Guess a number between 1 and 1024: ");
guess = Integer.parseInt(inputString);
if(guess < number){
JOptionPane.showMessageDialog(null,"Too Low");
}
if(guess > number){
JOptionPane.showMessageDialog(null,"Too High");
}
if(guess == number){
JOptionPane.showMessageDialog(null,"Correct! You win!");
on_off = 0;
}
}
}
}

Please edit your post and wrap the code in code tags. See: BB Code List - Java Programming Forum

Yes, until on_off is not 1

Why use a numeric (int) variable to test a boolean condition? Or haven't you yet been taught booleans?

what would you suggest?

A boolean variable.
