how does jvm detects deadlock condition. What is the data structure and algorithm JVM implements to detect htread deadlock.

Question

I have been trying to find whether JVM has some way to find if some threads are in deadlock condition. I am unable to find any. Please let me know if any one of you gets any pointer on this.

You can use the ThreadMXBean JMX bean.

ThreadMXBean threadMXBean = ManagementFactory.getThreadMXBean();
ThreadInfo[] threadInfos = threadMXBean.dumpAllThreads(true, true);
long[] deadlockedThreads = threadMXBean.findDeadlockedThreads();
long[] monitorDeadlockedThreads = threadMXBean.findMonitorDeadlockedThreads();

No, the JVM itself does not support deadlock detection.
There is a thread that deals with JVM and deadlocks, which is also marked as resolved: Link
