I\'m somewhat new to multithreaded environments and I\'m trying to come up with the best solution for the following situation:
I\'m writing a java implementation for two-phase locking. So, I\'m using Reentrant lock (ReadWrite lock). The problem is that when a thread executes the lock.readLock.lock() or lock.writeLock().lock()
It seems pretty clear that using readLock when reading from a file (for example), and using writeLock when writing to it is appropriate.However, if I have an operation where two values are being compa
I am using Java 6, and reading through Java Concurrency in Practice.I am trying to figure out if when using these methods, if a dormant thread waiting for the lock us开发者_StackOverflow社区es any CPU
I have a cache that gets loaded upfront with a large amount of data (by a background thread) and is unusable until full (it will also get reloaded every so often and be unusable during that load).I wa
Disclaimer: I\'m not very good at Java and just comparing read/writer locks between C# and Java to understand this topic better & decisions behind both implementations.
can anybody expla开发者_StackOverflowin this why its happening int i=0; i=i++; i=i++; i=i++; System.out.println(i);
I have three forms similar to the one in the link. I want add a Total textbox to every form. The total will add the v开发者_如何转开发alues that will be entered in the montant textbox.
