计算JAVA源代码行数的代码详解编程语言

* ********************************************** * @description 计算源代码（src）行数，不计算空行 * 宗旨：将src下所有文件组装成list,再筛选出文件，对文件进行遍历读取 *********************************************** public class LineCounter { List File list = new ArrayList File int linenumber = 0; FileReader fr = null; BufferedReader br = null; public void counter(String projectName) { // String path = System.getProperty("user.dir"); String path = LineCounter.class.getResource("/").getPath(); // 同下个path path = path.substring(0, path.length() - 24) + projectName + "/src/main/java"; System.out.println(path); File file = new File(path); File files[] = null; files = file.listFiles(); addFile(files); isDirectory(files); readLinePerFile(); System.out.println("Totle:" + linenumber + "行"); // 判断是否是目录 public void isDirectory(File[] files) { for (File s : files) { if (s.isDirectory()) { File file[] = s.listFiles(); addFile(file); isDirectory(file); continue; //将src下所有文件组织成list public void addFile(File file[]) { for (int index = 0; index file.length; index++) { list.add(file[index]); // System.out.println(list.size()); //读取非空白行 public void readLinePerFile() { try { for (File s : list) { int yuan = linenumber; if (s.isDirectory()) { continue; fr = new FileReader(s); br = new BufferedReader(fr); String i = ""; while ((i = br.readLine()) != null) { if (isBlankLine(i)) linenumber++; System.out.print(s.getName()); System.out.println("/t/t有" + (linenumber - yuan) + "行"); } catch (Exception e) { e.printStackTrace(); } finally { if (br != null) { try { br.close(); } catch (Exception e) { if (fr != null) { try { fr.close(); } catch (Exception e) { //是否是空行 public boolean isBlankLine(String i) { if (i.trim().length() == 0) { return false; } else { return true; public static void main(String args[]) { LineCounter lc = new LineCounter(); String projectName = "/maps1.2"; //这里传入你的项目名称 lc.counter(projectName);
