3,934 PointsCreating an object over and over again
In the lectures all code lines where object was created were moved outside of the method. Why do you create object of String over and over again inside of the method? Why did you not declare it as a global variable? For example, here fact is created everytime when we call getColor() method:
public String getColor() { String fact = ""; Random randomGenerator = new Random(); int randomNumber = randomGenerator.nextInt(mColors.length); fact = mColors[randomNumber]; return fact; }

10,365 PointsHi Beksultan,
the "fact" String variable is a lokal variable. If you put this variable outside the method it will become a class variable and it will be created when you create this class, or the object of this class.
The good part of the lokal variable is, that it is only visible for the method and not for the outside world.
Does it make sense?
