Finding Method Caller Using Stacktrace or Reflection

Question: How can I determine the caller of a method using stacktrace or reflection?

Answer:

To obtain the caller information:

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

As per the documentation, the array's last element represents the bottom of the stack, indicating the oldest method invocation in the sequence.

Each StackTraceElement provides methods like:

• getClassName()
• getFileName()
• getLineNumber()
• getMethodName()

To determine the caller's details, experiment with different array indices. Typically, stackTraceElements[1] or [2] should provide the desired information.
