How do I find the caller of a method using stacktrace or reflection?

Question

I need to find the caller of a method. Is it possible using stacktrace or reflection?

Answer 1

StackTraceElement[] stackTraceElements = Thread.currentThread().getStackTrace()

From the Javadocs:

The last element of the array represents the bottom of the stack, which is the least latest method invocation in the sequence.

A StackTraceElement has getClassName(), getFileName(), getLineNumber() and getMethodName().

You will have to test to decide which index you require (apparently stackTraceElements[1] or [2]).
