Will an exception occur in case of a deadlock in the system?

In Java, deadlock exceptions do not occur automatically. Deadlock is a situation where two or more threads wait forever for resources held by each other.

Java does not detect deadlocks automatically and does not throw exceptions. To identify deadlocks, profiling or thread monitoring tools (such as jstack) can be used, which will show which threads are blocked and on which resources.

To prevent deadlocks, strategies such as lock ordering, timeouts when acquiring locks, or using high-level synchronization constructs are employed.
