We can use ThreadMXBean.findDeadlockedThreads() method to

detect deadlocks in Java program. This bean comes with JDK:

Sample code is as follows:

ThreadMXBean bean = ManagementFactory.getThreadMXBean();

long[] threadIds = bean.findDeadlockedThreads(); // It will return

null for no deadlock

if (threadIds != null) {

ThreadInfo[] infos = bean.getThreadInfo(threadIds);

for (ThreadInfo info : infos) {

StackTraceElement[] stack = info.getStackTrace();

// Log or store stack trace information.

}

}
