[Java] 監看誰呼叫了目前的程式

今天要找一個奇怪的bug，需要追踨整個Java Class呼叫的Stack

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

According to the Javadocs:

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

A StackTraceElement has getClassName(), getFileName(), getLineNumber() andgetMethodName().

You will have to experiment to determine which index you want (probably stackTraceElements[1] or[2]).
