1. What are the potential issues with using synchronized blocks for thread synchronization in Java? Answer: Example Scenario:Two threads trying to acquire locks on two objects in different order, leading to deadlock: 2. Explain the “happens-before” relationship in the Java Memory Model (JMM)...
Languages like Java, Smalltalk, C# contain all the high level objects and language constructs that provide threading, synchronization, and timers but used an operating system to provide those services. The JikesRVM has made it possible to implement the lower level services that where provided by ...
A CountDownLatch is a versatile synchronization tool and can be used for a number of purposes. A CountDownLatch initialized with a count of one serves as a simple on/off latch, or gate: all threads invoking await wait at the gate until it is opened by a thread invoking countDown(). A...
For example if the access to the containers would take only 10% of the overall time (while some calculation takes 90%) then the overhead of the thread synchronization would also be much less - relative to the total execution time. 2 added 371 characters in body Source Link Full edited...

Synchronization tracing for Java programs is based on events generated when a thread attempts to acquire a Java Monitor. Both machine call stacks and Java call stacks are collected for these events, but no synchronization tracing data is collected for internal locks used within the JVM software. ...
Java File Sync Brian Tannous November 2010 ---About--- Java File Sync is a simple directory tree synchronization program written in java. Jfs is currently a command line only program and is can be ran anywhere. It requires a sever to host the sync directories. You can easily sync ...
