Second, problem-solving ideas
2.1 Basic Requirements Analysis
After carefully reading the title analysis reveals the basic needs of the project are as follows:
| wc.exe -c // returns the number of characters in the file file.c |
| wc.exe -c // returns the number of characters in the file file.c |
| Wc.exe -w // Returns the file number of words file.c |
| wc.exe -l // returns the number of rows of file file.c |
| wc.exe -a // return more complex data (line / space lines / comment lines) |
| wc.exe -s // recursive processing files that meet the conditions of the directory. |
| wc.exe -x // display a graphical interface |
2.2 realization of ideas
Because this project need to make a graphical interface, and the need to use more string manipulation, considering the development efficiency and process efficiency, and ultimately choose Java as a development language, using Javafx graphical interface development. Because not done before Javafx project, so it is necessary to find a Javafx use of tutorials to learn. Overall project requires parsing command console input function, file reading function, function, function graphical interface statistics text messages and so on.
Third, the design program
3.1 System Architecture
Use basic MVC structure:
System flowchart 3.2
The system flow chart is as follows:
Fourth, the project difficulty
4.1 How to file statistics accurately
Traversal using progressive way, statistics the number of characters per line, words, and finally get a summary total number of rows, information on the total number of characters, words, and so on.
4.2 How to build a graphical interface
Use scenebuilder build a basic graphical interface.
4.3 How to recursively traverse to find files in the folder in line with wildcards.
The wildcard user input converted to regular expressions, recursive get all the files in the current directory, file name matches one by one, to get eligible files.

Eight, Project Summary
This project gives me the biggest difference is the use of the PSP table to manage their own time, from the actual results, the actual time-consuming slightly more than some of his plans will mainly have some problems are not expected within and, in the process of writing code also continued to generate new ideas, will generate more demand. The place is more time-consuming forms graphical interface, beginning just do a single interface file information display, but then I want to do more than file before he went to learn to use javafx table, Javafx do indeed form a little trouble, it took some time to learn its use, in general, the harvest is still a lot of.
