之前因為需要統(tǒng)計一個項目的代碼行數(shù)胸哥，源代碼在不同目錄下材蹬，不好統(tǒng)計，所以寫了個遍歷指定目錄下所有文件夾文件統(tǒng)計行數(shù)的方法統(tǒng)計源代碼规惰。
private static int allCount = 0;
private static int fileNum = 0;
public static void countLine(File rootFile) {

for (File file : chileFileList) {
if(file.isDirectory()) {
countLine(file);
}else {

try {

while(sc.hasNextLine()) {

sc.nextLine();
}
System.out.println(file.getAbsolutePath()+" : "+count+">>>第"+fileNum+"個文件");
allCount+=count;
