I've been following an online tutorial and even though I have my html file and java class file in the same folder I get errors from the Java console saying the class can't be found? Here's my code and errors:

while (true)

// set ThreadPriority to maximum value
Thread.currentThread().setPriority(Thread.MAX_PRIORITY);
}
