Get stack trace and follow your execution path

Sometimes you don't have enough time to analyse source application architecture/UML diagrams etc.
If it is an urgent issue (needed to be FIX asap like always :-p) you want to learn program execution path to understand what it is doing !

new Throwable ().printStackTrace(); gives you what you want

Lets have a look at it.

public class GetStackTrace {
  public static void main (String[] args) {
    GetStackTrace obj = new GetStackTrace ();
    obj.methodOne();
  }
  public void methodOne (){
    System.out.println (" -- im in the method one.");
    methodSeven ();
  }
  public void methodTwo (){
    System.out.println (" -- im in the method two.");
    methodFour();
  }
  public void methodThree (){
    System.out.println (" -- im in the method three.");
  }
  public void methodFour (){
    System.out.println (" -- im in the method four.");
    methodSix ();
  }
  public void methodFive (){
    System.out.println (" -- im in the method five.");
  }
  public void methodSix (){
    System.out.println (" -- im in the method six.");
    new Throwable ().printStackTrace();
    methodFive ();
  }
  public void methodSeven (){
    System.out.println (" -- im in the method seven.");
    methodTwo ();
  }
}

And it's output is here :


-- im in the method one.
-- im in the method seven.
-- im in the method two.
-- im in the method four.
-- im in the method six.
