Task 1: Create a new public method named isBatteryEmpty that returns true if the battery has 0 bars remaining, and false otherwise.

You need to test to see if the value of barCount is 0. If it is you would then return the boolean 'true'. If it isn't you can let the default return value be the boolean 'false'.

  public boolean isBatteryEmpty() {
    if (barCount == 0) {
      return true;
    return false;
