Simple way to display FILE and LINE NUMBER from java source codes similar to C++ __LINE__

Have you ever wanted to be able to display the __file__ name, __line__ number and __method__ name from within Java class for quick debugging? Well, perhaps the following utility will help:

Save the following code in a file name __.java

package org.cnci.util;

/*
* Simple utility class to display __LINE__ number, __FILE__, __METHOD__ and __CLASS__ name for debugging...
* @author TA Nguyen
*/

public class __ {

 // __.LINE__() similar to __line__ in C++
 public static int LINE__() {
  return Thread.currentThread().getStackTrace()[2].getLineNumber();
 }

 // __.METHOD__()
 public static String METHOD__() {
  return Thread.currentThread().getStackTrace()[2].getMethodName();
 }

 // __.CLASS__()
 public static String CLASS__() {
  return Thread.currentThread().getStackTrace()[2].getClassName();
 }

 // __.FILE__() similar to __file__ in C++
 public static String FILE__() {
  return Thread.currentThread().getStackTrace()[2].getFileName();
 }

 private static String testOne() {
  return "testOne:: " + " File:" + __.FILE__() + " Class:" + __.CLASS__()
    + " Method:" + __.METHOD__() + " Line:" + __.LINE__();
 }

 public static void main(String[] args) {
  String info = testOne();
  System.out.println("1. " + info);
  System.out.println("2. File:" + __.FILE__() + " Class:" + __.CLASS__()
    + " Method:" + __.METHOD__() + " Line:" + __.LINE__());
 }
}
