Android Build a Simple Android App (2014) Coding the Fun Facts Properties of Arrays

Isn't it more efficient to just make factLebal.setText(facts[randomNumber]); instead of declaring the 'fact' String ?

I mean maybe I'm wrong or ahead of time , but just for the sake of it I just tried it and it worked fine . It seems much more straight forward than declaring the String fact , setting it to be equal to fact just to than set factLebal's text to fact's String. Please share your thoughts on the subject , Is it right to do this the way I described ? will it cause problems along the way ?

This is more efficient, and your program will technically use less memory. I tend to do write my code like that a lot. You may run into some issues if you were to wrap that code in a loop and do some large iteration, depending on what goes inside the function. In that case it would make sense to declare the variable separately.

Yeah that's what I thought , I don't know much about loops yet tho . but i'll keep what you just told me in mind when ill get more into loops . Thanks !
