探索 java的File 类 renameTo(File)方法

在使用compass 时，发现重建索引重命名文件失败，看了源码，原来源码用了 File renameTo的方法，于是自己做了试验，结合网上一位朋友的帖子

下面看我的测试：

                boolean renamed = false;
		 File renameToIndexPathFile;
		 String path = "D:/apache-tomcat-7.0.6/webapps/cc/index/advertset";
		 File indexPathFile = new File(path);
		 int count = 1;
		 renameToIndexPathFile = new File(path + "-copy" + (count++)); 
		 renamed = indexPathFile.renameTo(renameToIndexPathFile);		 
		 System.out.println(renamed);

如果把上面代码的path 间隔符改成下面就成功了：

 String path = "D:\\apache-tomcat-7.0.6\\webapps\\cc\\index\\advertset";
