遍历文件路径python版，java版

python:

# 获取所有txt路径列表
file_list = []
def gci(filepath):
    files=os.listdir(filepath)
    for fi in files:
        fi_d=os.path.join(filepath,fi)
        if os.path.isdir(fi_d):
            gci(fi_d)
        else:
            file_list.append(os.path.join(filepath,fi_d))
gci('E:\data')

java:

public static void refreshFileList(String strPath) {
        File dir = new File(strPath);
        File[] files = dir.listFiles();   

        if (files == null)
            return;
        for (int i = 0; i < files.length; i++) {
            if (files[i].isDirectory()) {
                refreshFileList(files[i].getAbsolutePath());
            } else {
                String strFileName = files[i].getAbsolutePath().toLowerCase();
                filelist.add(files[i].getAbsolutePath());
            }
        }
    }
