"Since the early days of the Java programming language, some have argued that Java's being an interpreted language has made it inferior to the likes of C and C++ in terms of performance. Of course, C++ devotees would never, ever even consider Java a "proper" language, while the Java crowd always throws "write once, run everywhere" in the faces of the C++ programmers.

"First things first, how well does Java perform when it comes to basic integer arithmetic? If I asked you how much 2 x 3 is, you would probably answer in no time. How long would it take a program? To check, here's a basic test:

"1. Generate first X numbers of random integer numbers.
2. Multiply those numbers with every number from 2 to Y.
3. Compute how long it takes to perform the whole set.

"Because you're not interested in how long it takes to generate a random number, it is important that you generate the random numbers upfront, before you start measuring."
