public class IteratedArithmeticException extends Throwable {
  private int iteration = 0;	// Iteration number at which exception occurred.

  // Default Constructor:

  // Standard constructor:
  public IteratedArithmeticException(String s) {
    super(s);				// Call the base constructor.
  }

  public IteratedArithmeticException(int iteration) {
    super();				// Call the base constructor.
    this.iteration = iteration;		// Set the iteration number.
  }

  // Get the array index value for the error:
  public int getIteration() {
    return iteration;			// Return the iteration number.
  }
}
