Hi Khankh,

you are damn close to victory :)

First task should be absolutely fine:

   public boolean isBatteryEmpty(){
    return mBarsCount == 0; 
// the result of this line is true
//so boolean isBatteryEmpty is true
  }

the code for the second task needs a tiny change of the typo :)

  public boolean isFullyCharged(){ 
// you had isFullyCharger 
//you need isFullyCharged
    return mBarsCount == MAX_BARS; 
//here is everething easy and great
  }

Shout out if you need more help

Hi Khánh Nguyễn, In return mBarsCount = MAX_BARS, try using == instead of =.
