Use the static methods in the Math class for both - there are no operators for this in the language   double root   Math sqrt value   double absolute   Math abs value      Likewise there s no operator for raising a value to a particular power - use Math pow for that    If you use these a lot  you might want to use static imports to make your code more readable   import static java lang Math sqrt  import static java lang Math abs        double x   sqrt abs x    abs y      instead of  double x   Math sqrt Math abs x    Math abs y
