java 获取指定目录下所有文件的名称

需要将文件名称及路径存到数据库中

String path ="/db/java/Data3/";
			StringBuffer str = new StringBuffer("");
			File f = new File(path);
	        if (!f.exists()) {
	             continue;
	         }
	        File fa[] = f.listFiles();
	        for (int i = 0; i < fa.length; i++) {
	            File fs = fa[i];
		           if (fs.isDirectory()) {
		             } else {
		            	 str.append(path+fs.getName()+",");	 
		             }
		        }
