We should avoid this condition as much as we can. The utility also performs deadlock detection.
#JAVA DEADLOCK WITH 1 BJECT CODE#
Deadlock condition can break our code at run time and can destroy business logic. The jstack command-line utility attaches to the specified process or core file and prints the stack traces of all threads that are attached to the virtual machine, including Java threads and VM internal threads, and optionally native stack frames. For example, here is the another implementation of run () method without nested lock and program runs successfully without deadlock situation. This is when two or more threads cannot proceed because they are waiting for resources locked by one another.
Deadlock condition is a complex condition which occurs only in case of multiple threads. It’s almost impossible to get deadlock situation if you are working with only one object lock. A deadlock will bring your program to a grinding halt.
Deadlock occurs when multiple threads need the same locks but obtain them in a different order. Important Points : If threads are waiting for each other to finish, then the condition is known as Deadlock. Deadlock describes a situation where two or more threads are blocked forever, waiting for each other. While multi-threading helps in improving an applications performance, it also comes with some problems.
