How to get a caller class of a method

Question

How do I know which class called a method?

class A {
   B b = new B();

   public void methodA() {
    Class callerClass = b.getCallerCalss(); // it should b         


        

Answer 1

You can get the class name of the caller class by fetching the second element of the stack trace:

final StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();
System.out.println(stackTrace[1].getClassName());

The getClassName method of the StackTraceElement class returns with a String so you won't get a Class object unfortunately.
