Third, the problem-solving ideas
Because before JAVA class has similar functionality with this project, so I chose to use JAVA to achieve.
Functional Analysis
(1) counts characters (achieved by calculating the length of a text document content)
(2) the number of words statistics (through statistics the number of spaces between words)
(3) statistics rows ( '\ n' is achieved by counting the number)
(4) the number of blank lines to statistics, the number of comment lines, number of lines of code (use regular expressions to achieve)
(5) supports wildcards (unrealized)
(6) a graphical interface (not implemented)
(7) Under Process directories recursively eligible files (not implemented)
In the design of the graphical interface I had some problems, first frame, I need to build a certain window to resize the window to display the contents, I do have a review in accordance with the method to set the window size setSize (), and then display the form setVisible (), but that does not work, then that call methods and functions, but because of the previous code, I first determine the "-c, -l, -w" these instructions enable other class methods, and then enter the path of by judging the input command is completed, leading to calls and do not know how to use getPath () by choosing the file path to get input when creating a graphical interface, you need to recompile the front most of the code can be modified, ultimately, to abandon graphical interface, Although the statistical methods used in the class before all go into the graphical interface, but such codes are too bloated, just repeat the previous code, no use to other classes, become completely separated from the completion of the previous function class, but the most important thing is lack of personal coding ability, did not do pre-planning function, post-modification fatigue, As written by the same teacher in the program requirements, Practice Makes Perfect. There are no shortcuts, that is to practice, practice and more practice! After this simple personal project, I found my programming ability is really very low, so my future should strive to practice my programming skills, more training and more thinking, raise the level.
Fourth, the design and implementation process
There are six project categories:
1.WC (main class)
2.CodeCount (realized character statistics)
3.WordCount (realization word count)
4.LineCount (the number of rows to achieve statistical)
5.Extra (extended functionality, the number of blank lines, comments, number of rows, the number of lines of code statistics)
Fifth, test run
Test file
(1) character counts
(2) the word count
(3) the number of lines statistics
Statistics (4) blank line, a comment line number, the number of lines of code
Import java.util.Scanner; public class the WC { public static void main (String [] args) { System.out.println ( "************************************************************ ************************************************************ " ); System.out.println ( " instructions: " ); System.out.println ( " wc.exe -c // returns the number of characters in the file " ); System.out.println ( " wc.exe -w // returns the number of words in the file " ); System.out.println ( " wc.exe the -l // returns the file the number of rows " ); System.out.println ( " wc.exe -a // returns the number of empty lines in the file, the number of lines of code number of comment lines " ); System.out.println ("*********************************************" ); Scanner Scan = new new Scanner (the System.in); String Order = null ; the while ((scan.nextLine Order = ()) = "!" ) { Switch (Order) { Case "wc.exe -C": the System.out. println ( "Please enter a file path:" ); new new Codecount (); BREAK ; Case "wc.exe -w": System.out.println ( "Please enter a file path:" ); new new wordcount (); BREAK ; Case"wc.exe -l": System.out.println ( "Please enter a file path:" ); new new LineCount (); BREAK ; Case "wc.exe -a": System.out.println ( "Please enter a file path : " ); new new Extra (); BREAK ; default : System.out.println (" error command input, please re-enter the command: " ); } } scan.close (); }}

import java.io.File; import java.io.FileReader; import java.util.Scanner; public class Wordcount { Scanner w=new Scanner(System.in); String Pathname=null;{ while((Pathname=w.nextLine())!="") { File file=new File(Pathname);{ try { FileReader fr=new FileReader(file); char temp[]=new char[4096]; int b=0; int A = fr.read (TEMP); for ( int I = 0; I <A; I ++ ) { IF (TEMP [I] == '' ) B ++ ; } IF (A == -. 1) B = -1 ; System.out.println ( "number of words in the text as" + (B +. 1 )); fr.close (); } the catch (Exception E) { of System.out.print ( "file path for the error, re-enter: " ); } }}}}
import java.io.BufferedReader; import java.io.File; import java.io.FileReader; import java.util.Scanner; public class Extra { Scanner e=new Scanner(System.in); String Pathname=null; String kregex="(\\s)*[{]?";{ while((Pathname=e.nextLine())!="") { File file=new File(Pathname);{ try { String s=null; int a=0,c=0,b=0; FileReader fr=new FileReader(file); BufferedReader bufr=new BufferedReader(fr); while((s=bufr.readLine())!=null) { if(s.contains("//")) a++; else if(s.matches(kregex)) b++; else c++; } System.out.println("文本的空行数为:"+a); System.out.println ( "number of comment lines of text is:" + B); System.out.println ( "number of lines of text is:" + C); fr.close (); bufr.close (); } the catch (Exception E) { e.printStackTrace (); System.out.println ( "file path input errors, please re-enter:" ); } } } } }
import java.io.BufferedReader; import java.io.File; import java.io.FileReader; import java.util.Scanner; public class Linecount { Scanner l=new Scanner(System.in); String Pathname=null;{ while((Pathname=l.nextLine())!="") { File file=new File(Pathname);{ try { FileReader fr=new FileReader(file); BufferedReader bufr=new BufferedReader(fr); int I = 0 ; the while ((bufr.readLine ()) =! null ) { I ++ ; } System.out.println ( "number of lines of text as" + I); fr.close (); bufr.close ( ); } the catch (Exception E) { System.out.println ( "file path input errors, please re-enter:" ); } } }}}
