An example using a static class variable

Demo Code

public class Main {
  static int nbfunccalls = 0;

  static int square(int x) {
    nbfunccalls++;//from  w ww .j  a va2 s. c  o  m
    return x * x;
  }

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

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

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

  static double ff(double xx) {
    double xx1 = 0.0;
    return xx1;
  }

  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");

    System.out.println("Total number of function calls:" + nbfunccalls);
  }
}
