This is the point at which this throwable was created and thrown.

The last element of the array (assuming the array's length is non-zero) represents the bottom of the stack, which is the first method invocation in the sequence.

      catch(Throwable e) {
         // access to the stack trace
         StackTraceElement[] trace = e.getStackTrace();
         System.err.println(trace[0].toString());
      }
   }
  
   public static void ExceptionFunc()throws Throwable {

      Throwable t = new Throwable("This is new Exception...");
      StackTraceElement[] trace = new StackTraceElement[] {
         new StackTraceElement("ClassName","methodName","fileName",15)
      };

      // sets the stack trace elements
