How can i know in which method i am?

Question

I would like to know ( for debugging reasons ) in which Method the execution code is!
Like the printStackTrace() which indicates:
- package
- class
- method
- line
at mypackage.myclass.mymethod4(MyClass.java:40)
at mypackage.myclass.mymethod3(MyClass.java:30)
at mypackage.myclass.mymethod2(MyClass.java:20)
at mypackage.myclass.mymethod1(MyClass.java:10)
at java.lang.Thread.run(Thread.java:484)
Does anybody knows how to do this?
Bye

This will return the calling class.method() of a class.
public static String getCallingClassMethod() {
     try {
          Exception e = new Exception();
          // make a buffer to store the stack trace       
          java.io.ByteArrayOutputStream buffer = new java.io.ByteArrayOutputStream();
          java.io.PrintStream stackInfo = new java.io.PrintStream(buffer);
          e.printStackTrace(stackInfo);
          // create the tokenizer to get each line       
          java.util.StringTokenizer stackInfoParser =
               new java.util.StringTokenizer(buffer.toString(), "\n");
          int n = 4;
          // *nix system only need 4 tokens windows has 2 extra
          if (System.getProperty("os.name").startsWith("Windows"))
               n = 6;
          // loop through all the crap that comes before our calling method
          for (int i = 1; i < n ; i++){
               stackInfoParser.nextToken();
          // get our calling class.method
          String returnString = stackInfoParser.nextToken().trim();
          // get rid of the garbage
          returnString = returnString.substring(returnString.indexOf(" ") + 1,
               returnString.indexOf("("));
          return returnString;
     } catch (Exception e) {
     return "";
}
