Re: boolean help
Hello lotus.
You can do that like this:
import java.util.Scanner; public class lotus { /** * JavaProgrammingForums.com */ public static void main(String[] args) { Scanner myScanner = new Scanner(System.in); boolean mod = true; int myInt = 0; while (mod) { System.out.println("Enter 1 to modify, 0 to ok"); myInt = myScanner.nextInt(); mod = (myInt != 0); System.out.println("You entered: " + mod); } } }
Example output:
Enter 1 to modify, 0 to ok
1
You entered: true
Enter 1 to modify, 0 to ok
0
You entered: false

Re: boolean help
mod = (myInt != 0); what does this line of code actually do?
Re: boolean help
It checks to see if myInt is not 0 and if that is the case it will return true otherwise false.
mod equals (myInt not equals zero)
