Question

boolean r = false ; int s = 0 ;
while (r == false) ; 
{
    s = getInt() ; 
    if (!(s>=0 && s<=2)) System.out.println ("try again not a valid response") ; 
    else r = true ; 
}

The text never displays itself even when a 3 or a 123 is entered and the loop never terminates. Whats wrong here?

Answer 1

You have a semicolon after the condition. When you use braces to specify a block for your while you don’t use a semicolon.
