NEED HELP PLEASE!

Write a Java program to read a text file (command line input for file name), process the text file and perform the following.

Print the total number of words in the file.
Print the total number of different words (case sensitive, meaning “We” and “we” are two different words) in the file.
Print all words in ascending order (based on the ASCII code) without duplication.
Write a pattern match method to find the location(s) of a specific word (a character string up to twelve characters, e.g. system). This method should return all line number(s) and location(s) of the word(s) found in the file.
Print all line(s) with line number(s) of the file where the word is funds by invoking the method of 4). Under each output line indicate the location(s) of the first character of the matched word (refer to the output example below).
Empty lines are lines, they also have their own unique line numbers.
Repeat the pattern match (4 and 5 above) until user types in EINPUT.

A word is defined by any combination of alpha and numerical characters (starting with alpha character), all other characters are delimiters. Note: no word in the input text file will start with a numerical character.

Input

The name of the text file should be read in from the Command line arguments, the input text file has a maximum of 80 characters per line and the size of the text file is less than two pages.

java Project mytext.txt

The total number of different words in the file is: 465
Words of the input file in ascending order without duplication:
// here are output of all words in ascending order without duplication
