A question was raised today in my computer science class. The question went something along the lines of:
If you print out two ints joined by a plus sign, are they added or are they printed out separately?
My initial response that if you did something like println(10 + 11); it would print out 1011. I was [...]

Many beginner programmers aren’t taught what exactly the String[] args part means though. They’ll learn arrays eventually but they still won’t understand the point of [...]
No, not a Hash Table. A hash as in sha1 or md5. After a few days of searching and tinkering sometime in December 2007, I wrote this static driven Java Hash file for sha1. So if you want sha1 hashes in your program (for strings and files), this might help you out. At this point, [...]

Basically, you enter an int using Scanner.nextInt() and proceed to enter a string but just as you’re about to type it, you notice that your chance is gone! And [...]

The method is extremely simple but avoids sub-strings and annoying logic that sub-stringing brings.
Sadly in Java you [...]
