When i am trying to compile the code i found the following error

Error: Exception in thread "main" java.util.NoSuchElementException at java.util.StringTokenizer.nextToken(Unknown Source) at Input.(Input.java:84) at Input.main(Input.java:130)

Actually this is an implementation of a slicing algorithm. The class Input.java specifies the Input to the program with the help of a text file. Below I am attaching the text file named Input.txt. the input file is too large in size. Please let me know more about the flaws.
