1. Simulating a Deadlock In Java, adeadlock is a situation where a minimum of two threads are holding the lock on some different resource, and both are waiting for the other’s resource to complete its task. And, none is able to leave the lock on the resource it is holding. Deadlock...
Deadlock in java When two threads are waiting for each other forever means (i.e. it does not get a chance to enter in a ready queue) such type of infinite waiting is called deadlock. A deadlock occurs when the waiting process is still holding onto another resource that the first needs...
Deadlock is a programming situation where two or more threads are blocked forever, this situation arises with at least two threads and two or more resources. Here I have written a simple program that will cause deadlock scenario and then we will see how to analyze it. Java Deadlock Example...
but let the program move forward without crashing. In this type of scenario, the interrupt status can be reset without raising an exception, with the expectation that the code being executed next is going to handle the interrupt. This effectively delays handling the interrupt, but it doesn’t ...

Lock requests are queued (first come-first served); (unlike in some other languages where the lock is passed to some thread at random) navigator.locks.query()can be used to see what has the lock, and who are in the queue to acquire the lock ...
When working in a multithreaded application,it is important to handleInterruptedExceptiongracefully,and the threads should respond to interrupts promptly to avoid the application from entering into adeadlocksituation.
