It leads to deadlocks because a thread waiting for a lock may end up waiting for a lock held by another thread. Nested synchronization blocks occur when a thread acquires more than one lock in a nested manner. To avoid It, you should avoid nesting synchronized blocks. Several threads attempting to access the same resource while one is waiting for the other to relinquish it can lead to deadlocks. To avoid thread deadlocks in Java programs, you can follow these best practices: 1. How to avoid thread deadlock in Java Programs It can lead to deadlocks, increasing the likelihood of two or more threads acquiring locks in a different order. ![]() Avoid nested locks: Avoid acquiring locks on multiple objects in a nested fashion.These classes have already been designed and tested to handle multi-threading correctly. Use thread-safe classes: Instead of implementing your synchronization mechanism, use the thread-safe classes provided by the Java API.In order to avoid deadlock, it makes sure that only one thread can access the resources at once. Use a single lock: If possible, use one lock to protect multiple resources.If the lock cannot be acquired within the specified time, the thread can release the lock and try again later. Use timeouts: When acquiring locks, you can specify a timeout period.It allows other threads to acquire the lock and continue their execution. Release locks promptly: When a thread has finished using a shared resource, it should release the associated lock as soon as possible.It avoids the scenario where one thread is holding a lock that another thread requires, while the first thread is holding a lock that it needs the second thread to release. ![]() Acquire locks in a consistent order: If multiple threads need locks on multiple objects, make sure they always acquire the locks in the same order.Here are some ways to avoid thread deadlock in Java: It occurs when two or more threads become stuck while waiting the release of a resource that is necessary for them to continue running. Thread deadlock is a common problem that can occur in multi-threaded Java programs. Next → ← prev How to avoid thread deadlock in Java
