java实现wc功能
try (InputStream is = new FileInputStream(file)) { StringBuffer sb = new StringBuffer(); XWPFDocument xp = new XWPFDocument(is); XWPFWordExtractor wordReader = new XWPFWordExtractor(xp); String[] line = wordReader.getText().split("\n"); if (line.length < 1 || line == null) { return null; } for (int j = 0; j < line.length; j++) { System.out.println(line[j]); lineNum += 1; if (line[j].trim().toString().length() <= 1) { spaceLineNum += 1; continue; } String[] result = calcuChar(line[j]).split("=="); wordNum += Integer.parseInt(result[0]); charNum += Integer.parseInt(result[1]); } } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }
对于注释行的计算逻辑:
这里的注释指: // 和 /**/;对于 // 的校验相对简单,关键在于对 /**/的校验;这里flag就发挥了作用,即在前面的行扫描中是否遇到了/*.如果该次扫描检测到该行存在/*,flag则变为true,这样在一定程度上对后面扫描到的* 和*/能有一定的可鉴程度,当扫面到*或者*/时,flag为true代表改行为注释行,否则为代码或者空行,在尚未能够判断遇到的行是否为注释行时,temp负责存储存在疑问的行数,待能确定flag的值时,相当于计时器的存在.
boolean flag = false; int temp = 0; while ((line = br.readLine()) != null) { System.out.println("该行内容为：" + line); lineNum += 1; System.out.println(); if (line.trim().length() <= 1) { spaceLineNum += 1; continue; } if (line.trim().contains("//")) { annotationNum += 1; continue; } if (line.trim().contains("/*")) { temp += 1; flag = true; } if (!line.trim().contains("/*") && !line.trim().contains("*/") && line.trim().contains("*")) { if (flag) { temp += 1; } } if (line.trim().contains("*/")) { if (flag) { flag = false; annotationNum = temp + 1; temp = 0; if (lineNum > annotationNum) { lineNum = lineNum - annotationNum; } continue; } } }
字符的计算
这里对字符的计算进行封装,采取的策略是一行一行的计算字符,最后因为返回值限制,故而返回字符串形式,"词数==字符数",这里双等号的意义是为方便split方法.
public static String calcuChar(String line) { int wordNum = 0; int charNum = 0; for (int i = 0; i < line.split("\\s+").length; i++) { String tempWord = line.split("\\s+")[i].trim(); if ("".equals(tempWord) || tempWord == null) { continue; } if (pattern.matcher(tempWord).find()) { char c[] = tempWord.toCharArray(); //汉字前一个字母是否已经被算入 boolean flag = true; if (pattern.matcher(String.valueOf(c[0])).matches()) { wordNum += 1; charNum += 2; flag = false; } else { charNum += 1; } for (int k = 1; k < c.length; k++) { if (pattern.matcher(String.valueOf(c[k])).matches()) { if (flag) { wordNum += 1; flag = false; } wordNum += 1; charNum += 2; } else { flag = true; charNum += 1; } } if (flag) { wordNum += 1; } } else { wordNum += 1; charNum += line.split("\\s+")[i].trim().length(); } } return wordNum + "==" + charNum; }
图形界面的构建
最初采用hashmap存取组件来实现更新时获取对应组件进行更新.但后面因加入了多线程读取多个文件的缘故,舍弃了该方法,将图形界面的构建分成三部分,代码一是主界面的构建,也算是程序启动的入口.代码二是主界面按钮的实现以及监听事件;监听事件里每次读取到一个文件就new一个线程创建该文件的显示界面,再通过代码三来实现数据的绑定;这里用到的ResultVo是因返回参数的数量较多,故而将这些属性封装成一个类,参考代码四
public static void main(String[] args) { JFrame frame = new JFrame("主页面"); frame.setSize(350, 200); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel panel = new JPanel(); frame.add(panel); placeComponents(panel); // 设置界面可见 frame.setVisible(true); }
private static void placeComponents(JPanel panel) { panel.setLayout(null); JLabel userLabel = new JLabel("请选择文件:"); userLabel.setBounds(10, 20, 80, 25); JLabel findFiles = new JLabel("递归回显:"); findFiles.setBounds(10, 60, 80, 25); panel.add(userLabel); panel.add(findFiles); // 递归读文件 JButton jButton2 = new JButton("请选择文件"); jButton2.setBounds(100, 60, 100, 30); jButton2.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { JFileChooser chooser = new JFileChooser("C:\\Users\\hp\\Desktop"); chooser.setMultiSelectionEnabled(false); chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY); int returnVal; returnVal = chooser.showOpenDialog(jButton2); if (returnVal == JFileChooser.OPEN_DIALOG) { System.out.println(chooser.getSelectedFile()); List<String> pathList = findFilePath(chooser.getSelectedFile().getAbsolutePath()); if (pathList != null) { JFrame frame = new JFrame("文件列表"); frame.setSize(350, 200); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel panel = new JPanel(); frame.add(panel); frame.setVisible(true); int step = 10; for (String path : pathList) { System.out.println(path); JLabel fileName = new JLabel("文件:"+path); fileName.setBounds(10, 10+step, 80, 25); panel.add(fileName); step += 10; } } else { JOptionPane.showMessageDialog(null, "该文件夹下不存在符合条件的文件", "扫描失败", JOptionPane.ERROR_MESSAGE); } } } }); panel.add(jButton2); JButton jButton = new JButton("请选择文件"); jButton.setBounds(100, 20, 100, 30); jButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { JFileChooser chooser = new JFileChooser("C:\\Users\\hp\\Desktop"); chooser.setMultiSelectionEnabled(true); int returnVal; returnVal = chooser.showOpenDialog(jButton); if (returnVal == JFileChooser.APPROVE_OPTION) { File[] files = chooser.getSelectedFiles(); for (File f : files) { if (f.getAbsolutePath().substring(f.getAbsolutePath().lastIndexOf(".") + 1).equals("docx")) { new Thread(new Runnable() { @Override public void run() { ResultVo vo = ReadUtils.readDoc(f); if (vo == null) { JOptionPane.showMessageDialog(null, "文件路径错误", "扫描失败", JOptionPane.ERROR_MESSAGE); } else { JFrame frame = new JFrame("文件信息"); frame.setSize(350, 200); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel panel = new JPanel(); frame.add(panel); frame.setVisible(true); placeComponents(panel, vo); } } }).start(); } else if (f.getAbsolutePath().substring(f.getAbsolutePath().lastIndexOf(".") + 1).equals("txt") || f.getAbsolutePath().substring(f.getAbsolutePath().lastIndexOf(".") + 1).equals("java")) { new Thread(new Runnable() { @Override public void run() { ResultVo vo = ReadUtils.readTxt(f); if (vo == null) { JOptionPane.showMessageDialog(null, "文件路径错误", "扫描失败", JOptionPane.ERROR_MESSAGE); } else { System.out.println(1); JFrame frame = new JFrame("文件信息"); frame.setSize(350, 200); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel panel = new JPanel(); frame.add(panel); frame.setVisible(true); placeComponents(panel, vo); } } }).start(); } else { JOptionPane.showMessageDialog(null, "暂不支持对该类型文件的扫描 ", "错误 ", JOptionPane.ERROR_MESSAGE); } } } } }); panel.add(jButton); }
private static void placeComponents(JPanel panel, ResultVo vo) { JLabel fileName = new JLabel("文件名:" + vo.getFileName()); fileName.setBounds(10, 30, 80, 25); panel.add(fileName); JLabel charNum = new JLabel("字符数:" + vo.getCharNum()); charNum.setBounds(10, 40, 80, 25); panel.add(charNum); JLabel wordNum = new JLabel("词数：" + vo.getWordNum()); wordNum.setBounds(10, 55, 80, 25); panel.add(wordNum); JLabel lineNum = new JLabel("行数：" + vo.getLineNum()); lineNum.setBounds(10, 70, 80, 25); panel.add(lineNum); JLabel spaceLineNum = new JLabel("空行数：" + vo.getSpaceLineNum()); spaceLineNum.setBounds(10, 85, 80, 25); panel.add(spaceLineNum); JLabel annotationNum = new JLabel("注释行数：" + vo.getAnnotationNum()); annotationNum.setBounds(10, 100, 80, 25); panel.add(annotationNum); }

总结
最初是想用网页作为图形化界面,因为自身对前端的熟悉程度要远熟于java的swing.但最终还是选择了swing,也算作是复习.此次就我个人而言,正则表达式发挥了极大的作用,节省了不少代码量.加之其应用及其广泛,有时间需要好好弥补这方面的知识,这样用起来才能更加得心应手.
