According to Wikipedia:
The infinite monkey theorem states that a monkey hitting keys at random on a typewriter keyboard for an infinite amount of time will almost surely type a given text.
We don't have that kind of time, but what we do have are super smart monkeys. These monkeys are able to copy text.
So, guess what. We're starting a printing company powered entirely off of monkey typists.
Testing multithreaded applications is super difficult. Even more so, there's a chance that (if you're not actually
testing things correctly) your tests will occasionally pass when they shouldn't (since a poorly threaded application
isn't guaranteed to mess anything up). Instead, we're going to use the main method in
Monkey Typewriter to see
exactly what happens when things are threaded incorrectly vs correctly.
Made for you is an abstract base class of
Copier which has a constructor that takes a String and turns that into
an iterator. This will allow us to traverse the text to be copied and pass it along to each monkey (thread).
UnsafeCopier. Then, write a
run method that will have the monkey grab the next word and append
it to the copy.
MonkeyTypewriter to create 5 monkeys (threads) using the
UnsafeCopier and start them.
After the sleep, print out the results of the unsafely copied passage.
SafeCopier and then call that from the main method, in addition to the unsafe version.
