I was just curious to know if its a bad thing to have an if(){} construct without an else statement in java.
No of course not. There are several times when you only need an if statement without a corresponding else.

If the pattern of the directory of your images is always the same you can incorporate a regular expression to parse everything after EasyImage/.
You can use:
([^\/]+)(?=$)
It matches any character after the last slash.

I am an AP Computer Science student and I need help memorizing the algorithms.The algorithms are in a revision sheet and they are about abstract classes, interfaces, and polymorphism, so what would be the easiest way to memorize this.Thanks!
Try to understand and learn them.Never try to memorize as you'll sooner forget them
I would suggest don't try to memorize them instead understand the concepts and logics used in any algorithm

What function in java gives you the output of these:
05e0
01e1
42e0
66e6
I've tried exp() and expm() but doesn't give the right answer.
I think you want
Double.valueOf("66e6");
