A deadlock refers to a situation where two or more threads are permanently blocked, unable to proceed with their execution because each thread is waiting for a resource that is held by another thread in the deadlock cycle. As a result, the threads end up waiting indefinitely, leading to a ...
Deadlock in javaWhen 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: It is the situation in which two or more threads are blocked at any time. They will no longer operate further. This is because the threads wait for each other endlessly. Starvation and Livelock: They don’t create serious issues like a deadlock. However, they need to be rectifi...
completing the first thread that makes the code synchronized, and this is the benefit of the monitor. It is helpful in multithreading programming when multiple threads request the same resource. We need to create such a system to avoid any deadlock or starvation problem. See the example below....
