Is there a way to dump a stack trace without throwing an exception in java?

You can also try Thread.getAllStackTraces() to get a map of stack traces for all the threads that are alive.​​​​​​


If you want the trace for just the current thread (rather than all the threads in the system, as Ram's suggestion does), do:

Thread.currentThread().getStackTrace()

To find the caller, do:

private String getCallingMethodName() {
    StackTraceElement callingFrame = Thread.currentThread().getStackTrace()[4];
    return callingFrame.getMethodName();
}

And call that method from within the method that needs to know who its caller is. However, a word of warning: the index of the calling frame within the list could vary according to the JVM! It all depends on how many layers of calls there are within getStackTrace before you hit the point where the trace is generated. A more robust solution would be to get the trace, and iterate over it looking for the frame for getCallingMethodName, then take two steps further up to find the true caller.


Yes, simply use

Thread.dumpStack()
