Which is the best way for a called function to identify caller class name.

Question

Which is the best way for a called function to identify the caller class name .
1)Using sun.reflect.Reflection from called function
                Class caller = Reflection.getCallerClass(2);
                System.out.println("Caller Class Name ::"+caller.getName());2) Analyzing current threads stack trace from called function
                StackTraceElement[] stElements=Thread.currentThread().getStackTrace();
                System.out.println("Caller Class Name ::"+stElements[3].getClassName());Is there any alternate ways to achieve the same .Which is the best way ?
Called function doesn’t have any arguments, I don’t want t pass any arguments from caller function to called function.
Plz help.
With kind regards
Paul

Is there any alternate ways to achieve the same.SecurityManager
    // 0 is the anonymous SecurityManager class
    // 1 is this class (also works in static context)
    // 2 is calling class
    static Class getClass(int i) {
        return new SecurityManager() {
            protected Class[] getClassContext() {
                return super.getClassContext();
        }.getClassContext();
