Hey Andile! If you are having trouble solving this task, go back to the video and re-watch it and see 01:41 for the instructions on how to make a helper method. You would need to follow the same template for this task, just with different variables and values.

For the first task, creating isBatteryEmpty, you need it to return a boolean which checks if the mBarsCount is less than 1, meaning that there are no bars and therefore the battery is empty. For the second task, creating isFullyCharged, you need to return a boolean if the mBarsCount is equivalent to the MAX_BARS, meaning that the battery is fully charged to it's max capacity, the MAX_BARS constant. If you're still having trouble, comment below and I'll help you solve it. Good luck!
