How to Implement File Locking Feature in Java
How to implement FileLocking feature in java As we know within the java application we can avoid concurrent writes/read from different threads using synchronization/Locks as shown below. Using synchronized keyword we can make complete method thread safe. Using Lock we can make some portion of the code thread safe.
