       System.out.println(getTreeMap());
   }

   private static TreeMap<Double,String> getTreeMap() throws Exception{
       TreeMap<Double,String> res= new TreeMap<Double,String>();
       Scanner sc = new Scanner(new File("myFile.txt"));
       while(sc.hasNextLine()) {
           // reading first and last names and making it as full name
           String name=sc.next()+" "+sc.next();
           //reading salary from file
           double salary=sc.nextDouble();
           //adding to tree map salary as key and name as value
