Getting a method's calling method in Java

2010-10-10 13:09

In some situations it could be handy to figure out who called a specific method at runtime, especially when a specific method is used by hundreds of methods and you have no clue how to recreate the execution.

This can either be done by using external Java profilers which reads and analyse a Java applications memory usage or you can get the caller method programmatically within the application at runtime.

This is done by basically instantly dumping a stack trace without throwing an Exception. However dumping the stack trace (with or without creating an Exception) has a huge performance cost and should really only be done at temporarily special circumstances.

If you would like to get the stack traces of all active threads you can use:


If you only need the stack trace for the current thread you can use:


To get the calling method you can create a fancy method like:

private static String getCallingMethodName() {

    StackTraceElement stack = Thread.currentThread().getStackTrace()[3];
    return stack.getClassName() + "." + stack.getMethodName();
