Description:
Write a program as follows:(in Java)
[Objective] The program reads from a text file and creates a report file as to frequency of each letter (alphabets only) contained in the text file. In the report file, the most frequently used letter with its frequency is displayed first.
[Command Line Interface] The program is to be run from the DOS (command) prompt window as follows:
java LetterFreq inputFile outputFile
where LetterFreq is the java class name, inputFile is the name of any text file,
and outputFile is the name of the report file.
For example, if we type from the dos prompt window:
java LetterFreq essay1.txt result.txt
Then, the program reads essay1.txt file, and creates result.txt where letter frequency information about the essay1.txt file is stored.
The report file may look like: (Note that sorting is done based on the frequency)
BE SURE TO USE sort method in Arrays class to do the sorting.
E 19.5%
S 8.1%
T 7.5%
…
Note that the program should inform the user if the command is not properly used. For example, both inputFilename and outputFilename should be provided at the dos prompt window. Also the program should handle all exceptions properly such as “file not found”, “file cannot be created”, etc.
Hint for the command line arguments
Suppose that you typed from the dos prompt window as follows
java LetterFreq aaa bbb
You can check at the main method what has been typed from the dos prompt window
public static void main(String[] args) {
System.out.println(args.length); // 2
System.out.println(args[0]); // aaa
System.out.println(args[1]); // bbb
Be sure to give javadoc stylecomments.
