Chapter 3, Exercise 9, Thinking in Scala

Integer.parseInt is from java.lang.Integer. I guess i could have used the "tfor" loop that I defined here, if I wanted this to look more like Java or more like what the exercise statement was asking for.

object c3x9 {
    def main ( args: Array[String] ) = {
        val limit = Integer.parseInt( args(0) );
        var cand = 2;
        while (cand < limit) {
            var is_prime = true;
            var test = 2;
            while (is_prime  &&  test*test <= cand ) {
                if ( (cand % test) == 0 ) {
                    is_prime= false;
                }
                else {
                    test = test +1;
                }
            } 
            if (is_prime)
                Console.println( cand + " is prime." );
            /*
            else
                Console.println( cand + " is not prime." );
            */ 
            cand = cand +1;
        }
    }
}
