Second, the project thinking
    • Basic requirements

      • -C Statistics File character count (Implementation)

      • -W Statistics file Word count (Implementation)

      • -L Statistics File line count (Implementation)

    • Extended Functionality

      • -s recursive processing directory for eligible files (Implementation)
      • -A returns the file code line/blank line/Comment line (Implementation)
    • Advanced Features

      • []-X graphical interface (not implemented)

  

Parameter Implementation section:

    • -C: Each read into a character, the counter plus one.
    • -W: Each read into a character that is not a word, and a character that belongs to a word before it, and the counter adds one. The initial assumption of the word character is that "a" ~ "Z" and "a" ~ "Z" shall prevail.
    • -L: Each read into a newline character, the counter plus one.
    • -A (blank line \ Comment line \ code line): one row per read, one-time statistics
    • -S: Enter the file path and continue typing to find the name of the file to support fuzzy search.
Third, the design realization process

Code Startup Class Main.java
public class Main {public static void main (string[] args) {Commandcontroller Commandcontroller = new Commandco        Ntroller ();            while (true) {System.out.println ("\n*********************************************");            SYSTEM.OUT.PRINTLN ("* * * * [filename] Returns the number of file characters * * *");            SYSTEM.OUT.PRINTLN ("* * * * [filename] Returns the number of file words * * * *");            SYSTEM.OUT.PRINTLN ("* * * * [filename] Returns the number of file lines");            SYSTEM.OUT.PRINTLN ("* * * * [folder] Search file name * * * *");            SYSTEM.OUT.PRINTLN ("* * * * [file name] Statistics code line/blank Line/Comment Line * * * * * * *);            System.out.println ("*********************************************");            System.out.print ("Please enter command:");            Scanner s = new Scanner (system.in);            String m =s.nextline ();            String arr[]=m.split ("\\s");            Commandserver Server = Commandcontroller.searchcontrolscommand (arr[0]);        Server.command (arr[1]); }    }}

  

Commandcontroller
public class Commandcontroller {public    commandserver searchcontrolscommand (String command) {        commandserver Server = null;        Switch (command) {case            "-C": Server = new Charactercountserver (); break;//Returns the number of file characters case            "-W": Server = new Wordcoun Tserver (); break;      Returns the number of file words case            "-l": Server = new Rowcountserver (); break;       Returns the number of file lines case            "-S": Server = new Conditionfileserver ();  Search file name Case            "-a": Server = new Complexcountserver (); break;   Statistic code line/blank line/Comment line            default:                System.out.println ("parameter input is incorrect");        }        return server;    }}
