java - Return Min/Abs of 3 numbers -

i'm working on assignment i'm supposed return smallest of 3 values (absolute values, program states). worked when there 2 values needed returned, added 3rd one, started saying "cannot find symbol" @ math.min inside method. :( can't see problem is?

   public class threeseven_rasmusds     {     //start of smallerabsval           public static int smallerabsval(int a, int b, int c)         {                 int val = (math.min(math.abs(a), math.abs(b), math.abs(c)));               return val;     }     //end of smallerabsval            public static void main(string[] args)           {             int val = smallerabsval(6, -9, -3);           system.out.println(val);      }     //end of main      }     //end of class 

the math.min lib method accepts 2 parameters. if want min of 3 values, need this:

math.min( a, math.min(b, c) ); 

in context:

int val = math.min(math.abs(a), math.min(math.abs(b), math.abs(c)));
