How to handle file concurrency if two different applications (different JVM's) try to edit same file. What is the best way to handle this scenario. Thanks.

Ideally when one file is open in write mode another process should be able to overwrite that file. However the more clean way is to use FileChannel and FileLock classes in java.nio packages. All you have to do is


lock() is a blocking method. You can use tryLock() version which doesn't block the call.
