項目需求

實現一個wc統計程序,可以對文本進行相關功能的統計與分析

  • 基本功能
    • -c 統計字符數
    • -w 統計文件詞數
    • -l 統計行數
  • 擴展功能
    • -s 遞歸搜索目錄下面的文件
    • -a 返回更復雜的數據(代碼行 / 空行 / 註釋行)

設計

主函數思路:分析命令並對-s進行預處理,得到相應的文件名字,搜索該目錄下匹配的名字,根據是否需要遞歸進行分析,再對一條命令的每一個參數進行匹配,每次從文件讀取一行字符串進行分析,再把結果打印出來。

代碼

主函數

import java.io.*;
import java.util.Scanner;

public class Main {

    private static final Scanner scanner = new Scanner(System.in);

    public static void main(String[] args) {
        String s = null;
        while ((s = scanner.nextLine()) != null && !s.equals("exit")) {
            String[] strings = s.split(" ");

            boolean flag = false;

            for (String string : strings) {
                if (string.equals("-a")) {
                    flag = true;
                    break;
                }
            }



            File file = new File(strings[strings.length - 1]);
            String fileName = file.getName();
            if (!file.isDirectory()) {
                file = file.getParentFile();
            }
//            doFile(file,flag,strings,fileName);
            if (file != null && file.isDirectory()) {
                File[] files = file.listFiles(pathname -> {
                    if (pathname.isDirectory()) {
                        return true;
                    }
                    return isRight(pathname, fileName);
                });
                if (files != null) {
                    for (File file1 : files) {
                        doFile(file1, flag, strings, fileName);
                    }
                }
            } else {
                System.out.println("輸入文件有誤");

            }

        }
    }

    private static void doFile(File file, boolean flag, String[] args, String fileName) {
        if (file != null && file.isFile() && isRight(file, fileName)) {
            try (BufferedReader bf = new BufferedReader(new FileReader(file))) {
                String line;
                Result result = new Result();
                while ((line = bf.readLine()) != null) {
                    analyze(line, args, result);
                }
                result.print(file.getName());
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        if (file != null && flag && file.isDirectory()) {
            File[] files = file.listFiles(pathname -> {
                if (fileName.equals("") || pathname.isDirectory()) {
                    return true;
                }
                return isRight(pathname, fileName);
            });
            if (files != null) {
                for (File file1 : files) {
                    doFile(file1, true, args, fileName);
                }
            }
        }
    }

    private static void analyze(String line, String[] args, Result result) {
        for (String arg : args) {
            switch (arg) {
                case "-w":
                    new WordCheck(result).check(line);
                    break;
                case "-l":
                    new LineCheck(result).check(line);
                    break;
                case "-c":
                    new CharCheck(result).check(line);
                    break;
                case "-s":
                    new StructureCheck(result).check(line);
                    break;
            }
        }
    }

    private static boolean isRight(File file, String fileName) {
        if (fileName.startsWith("*")) {
            return file.getName().endsWith(fileName.substring(fileName.lastIndexOf(".")));
        } else {
            return file.getName().equals(fileName);
        }
    }
}

字符統計

public class CharCheck implements Check {

    private final Result result;

    public CharCheck(Result result) {
        this.result = result;
    }

    @Override
    public void check(String s) {
        result.addCharLine(s.length());
    }
}

根據每一行的字符串得出長度就是字符數

統計單詞

public class WordCheck implements Check {

    private final Result result;

    public WordCheck(Result result) {
        this.result = result;
    }

    @Override
    public void check(String s) {
        s = s.replaceAll("[\\p{Nd}\\p{Punct}\\s]", " ");
        result.addWord(splitWorker(s).length);
    }


    private String[] splitWorker(final String str) {

        if (str == null) {
            return null;
        }
        final int len = str.length();
        if (len == 0) {
            return new String[]{""};
        }
        final List<String> list = new ArrayList<>();
        int sizePlus1 = 1;
        int i = 0, start = 0;
        boolean match = false;
        final char sep = " ".charAt(0);
        while (i < len) {
            if (str.charAt(i) == sep) {
                if (match) {
                    if (sizePlus1++ == -1) {
                        i = len;
                    }
                    list.add(str.substring(start, i));
                    match = false;
                }
                start = ++i;
                continue;
            }
            match = true;
            i++;
        }
        if (match) {
            list.add(str.substring(start, i));
        }
        return list.toArray(new String[list.size()]);
    }
}

使用正則表達式去除標點符號然後切割

統計行數

public class LineCheck implements Check {

    private final Result result;

    public LineCheck(Result result) {
        this.result = result;
    }

    @Override
    public void check(String s) {
        result.addLine(1);
    }

}

每一次就加1

統計復雜數據

public class StructureCheck implements Check {

    private final Result result;


    public StructureCheck(Result result) {
        this.result = result;
    }

    @Override
    public void check(String s) {
        if (s.length() == 0) {
            result.addBlankLine(1);
            return;
        }
        for (int i = 0; i < s.length(); i++) {
            if (i == s.length()-1 && s.charAt(i) == ‘ ‘) {
                result.addBlankLine(1);
                return;
            }
            if (s.charAt(i) != ‘ ‘) {
                break;
            }
        }
        boolean flag = false;
        for (int i = 0; i < s.length(); i++) {
            if (s.charAt(i) == ‘/‘ && i + 1 < s.length() && s.charAt(i + 1) == ‘/‘) {
                result.addAnnotationLine(1);
                return;
            }

            if (s.charAt(i) == ‘/‘ && i + 1 < s.length() && s.charAt(i + 1) == ‘*‘) {
                flag=true;
            }
            if (s.charAt(i) == ‘*‘ && i + 1 < s.length() && s.charAt(i + 1) == ‘/‘ && flag) {
                result.addAnnotationLine(1);
                return;
            }
        }

        result.addCodeLine(1);
    }
}
