    array = new int[nbmax];
    index = -1;
    System.out.println("Succesfully created a stack array object...");
  }

  // Methods
  void Push(int element) {
    if (index < nbmax - 1)
      array[++index] = element;
  }

  int Pull() {
    if (index >= 0)
      return array[index--];
    else
      return -1;
  }

public class Main {
  public static void main(String[] args) {
    StackArray myStack = new StackArray(10);
    int i;

    for (i = 0; i < 10; i++)
      myStack.Push(i);

    for (i = 0; i < 15; i++)
      System.out.println(myStack.Pull());

  }
