Example here have to be split one per file, because they are either non-deterministic or take a perceptible amount of time to run.

• HelloWorld.java
• Main.java
• ExceptionTest.java
  • UncauthExceptionHandlerTest.java
• Deadlock.java
• Volatile.java

TODO:

• ConcurrentMap and other concurrent collections

  • replace: replaces only if the value exists / equals an older value. Does the check and insert atomically.

• AtomicInteger and family.

  Vs volatile boolean: http://stackoverflow.com/questions/3786825/volatile-boolean-vs-atomicboolean Same as volatile int, but with less compound operations.

• CountDownLatch

• ThreadLocal

• ThreadLocalRandom

• Executor

  • ExecutorService

    • ForkJoinPool
    • http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ThreadPoolExecutor.html

• ForkJoinTask

  • RecursiveAction

The synchronization primitives provided by the Java language are:

• volatile field modifier keyword
• synchronized method modifier or (TODO block modifier?) keyword
• Object.wait(), Object.notify() and Object.notifyAll() magic class methods

Besides those, there are many more convenient higher level interfaces provided by the JCL under java.util.concurrent:

• synchronized containers like LinkedBlockingQueue
• atomic types under java.util.concurrent.atomic: AtomicInteger, etc.
• locks under java.util.concurrent.atomic
