使用静态类变量的示例

public class Main {

  static int nbfunccalls = 0;/* 来 自 时代Java - nowjava.com*/


  static int square(int x) {

    nbfunccalls++;

    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) {
  /**
  来 自 n o w j a v a . c o m - 时  代  Java
  **/

    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;
