具體程式碼如下：

public class FileInfo {
	public static void main(String[] args) throws Exception {
		getFileInfo("C:/Users/DELL/Desktop/wsdl/");
	}

	private static void getFileInfo(String filename) throws Exception {
		File file = new File(filename);
		if (file.isDirectory()) {
			File[] list = file.listFiles();
			for (int i = 0; i < list.length; i++) {
				System.out.println(list[i].getName());
				OutputStream out = new FileOutputStream(
						"C:/Users/DELL/Desktop/wsdl.txt", true);
				byte[] buff = (list[i].getName() + "\r\n").getBytes();
				out.write(buff);
				out.flush();
			}
		}
	}
}
