package algs12;

import stdlib.*;

public class XFields {
  public static int classVariable = 42;

  public int objectVariable = classVariable++;

  public void f(int localVariable1) {
    int localVariable2 = StdRandom.uniform (100);
    if (localVariable1 > 0)
      f (localVariable1 - 1);
  }

  public static void main (String[] args) {
    Trace.drawSteps ();
    Trace.run ();

    XFields a = new XFields ();
    XFields b = new XFields ();

    a.f(1);
    b.f(1);
  }

}

Here is the state just before the main function ends:
