Threads and Multithreading what are they?

For the last few posts, we’ve looked at naming things in our code. Now we’ll move on to something entirely different and look at threads and multi-threading in Java. Multitasking is the ability of an operating system to have more than one program executing simultaneously. Unless we have a machine with multiple processors, what really happens is that the operating system allocates small blocks of time to each application in turn, at a speed that makes it appear as though all the programs are executing simultaneously.
