Deadlock synchronized java

Deadlock occurs in Java when multiple threads block each other while waiting for locks held by one another. To prevent deadlocks, we can use the synchronized keyword to make methods or blocks thread-safe which means only one thread can have the lock of the synchronized method and use it, other threads have to wait till the lock releases other one acquires the lock. 

Example: Below is a simple example demonstrating a deadlock condition in Java.

Output:

Note: It is not recommended to run the program in an online IDE.

We can run the above source code locally, but it gets stuck in a deadlock, preventing execution.

Explanation:

• Thread t1 starts by acquiring a lock on the s1 and enters the test1() method of s1.
• Thread t2 starts by acquiring a lock on the s2 and enters the test1() method of s2.
• In the test1() method both threads try to acquire locks on each other’s objects but the locks are already held by the other thread causing both threads to wait indefinitely for the other to release the lock.
• Neither
