A basic demonstration class for defining and calling static functions

Demo Code

public class Main {

  static int square(int x) {
    return x * x;
  }/*from   w  w  w.  j a  v a2 s . c  o m*/

  static boolean isOdd(int p) {
    if ((p % 2) == 0)
      return false;
    else
      return true;
  }

  static double distance(double x, double y) {
    if (x > y)
      return x - y;
    else
      return y - x;
  }

  static void display(double x, double y) {
    System.out.println("(" + x + "," + y + ")");
    return; // return void
  }

  public static void main(String[] args) {
    display(3, 2);
    display(square(2), distance(5, 9));

    int p = 123124345;
    if (isOdd(p))
      System.out.println("p is odd");
    else
      System.out.println("p is even");
  }
}
