catching exceptions. how do i place the variables or method in exception cases.

class GoKart {
  public static final int MAX_BARS = 8;
  private String color;
  private int barCount;
  private int lapsDriven;

  public GoKart(String color) {
    this.color = color;
  }

  public String getColor() {
    return color;
  }
  public void charge() {
    barCount = MAX_BARS;
  }

  public boolean isBatteryEmpty() {
    return barCount == 0;
  }

  public boolean isFullyCharged() {
    return MAX_BARS == barCount;
  }

  public void drive() {

    try{
      drive(1);


    }catch(IllegalArgumentException iae){

      System.out.println("wrong");
  }

  public void drive(int laps) {
    try{ 
      lapsDriven += laps;
      if (laps < 0);
      barCount -= laps;

    }catch(IllegalArgumentException iae){
      if (barCount < 1);

      System.out.println("wrong");
    }   

  }
}
