You don't know jack about thread-safety
All you hotshot programmers need to drop what you're doing and secure a copy of Java Concurrency in Practice. 50 pages into the book my face was frozen in pure horror, as Brian Goetz and his friends happily ran over everything I ever thought I knew about thread-safe programming.
What do you think the following code will print to the console?
public class NoVisibility {
private static boolean ready;
private static int number;
private static class ReaderThread extends Thread {
public void run() {
while (!ready) Thread.yield();
System.out.println(number);
}
}
public static void main(String[] args) {
new ReaderThread().start();
number = 42;
ready = true;
}
}Unless your answer is "either zero, 42 or nothing at all" you really need to read the book before someone notices.
