Declaring variables inside loops, good practice or bad practice?
...their scope is restricted to inside the loop. It cannot be referenced nor called outside of the loop.

How do I use the new computeIfAbsent function?
...onacci(0)
memo.put(1,1L); //fibonacci(1)
}
And for the inductive step all we have to do is redefine our Fibonacci function as follows:
public static long fibonacci(int x) {

I'm trying to center an ImageView inside a LinearLayout horizontally and vertically, but I just can't do it.
The main reason why I'm not using a RelativeLayout for that is because I need the layout_weight (my Activity consists of four columns that should be equally divided, and also respon...
