本文介绍了一个Java程序，用于遍历指定目录及其子目录（如果启用的话）中的所有文件，并将文件名收集到一个Vector中。该程序通过读取配置文件来确定是否包括子文件夹。

import java.io.File; import java.io.IOException; import java.io.InputStream; import java.util.Properties; import java.util.Vector; public class TestUtil { private boolean IsIncludeSubFolder; public TestUtil() { InputStream in = this.getClass().getResourceAsStream("/config.properties"); Properties props = new Properties(); try { props.load(in); String value = props.getProperty("IncludeSubFolder"); this.IsIncludeSubFolder = "1".equals(props.getProperty("IncludeSubFolder")) ? true : false; } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } boolean getIsIncludeSubFolder() { return IsIncludeSubFolder; } /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub TestUtil test = new TestUtil(); Vector<String> files = new Vector<String>(); test.getFileList(files, "F://娱乐", test.getIsIncludeSubFolder()); for (String string : files) { System.out.println(string); } } public boolean getFileList(Vector<String> outFileLists,String filePath,boolean subFolderFlag) { if(outFileLists == null) { outFileLists = new Vector<String>(); } File file = new File(filePath); if(file.exists()) { File files[] = file.listFiles(); if(subFolderFlag) { for(int i = 0; i < files.length; i++) { if(files[i].isFile()) { outFileLists.add(files[i].getName()); } else if(files[i].isDirectory()) { getFileList(outFileLists, filePath + "//" + files[i].getName(), subFolderFlag); } } } else { for(int i = 0; i < files.length; i++) { if(files[i].isFile()) { outFileLists.add(files[i].getName()); } } } } else { return false; } return true; } }
