如何检查给定的本地路径是否可以在java中写入

Question

我想查看以下内容

A）路径类型：本地：C：\ program files \ cts \ ABCD_PP \ dd \

1）检查路径是否存在 2）如果路径存在，则检查路径是否可写（意味着应该能够在该路径上放置文件）。

也

B）共享路径：\\ mdyptcmedia101 \ transmit \ in \

它是与本地文件路径验证相同的程序还是不同的

在春季项目中使用Jdk 1.6。

请帮忙。

Answer 1

RTM：File.isDirectory()，File.canWrite()

Answer 2

File file = new File("...");
boolean canWrite = file.canWrite();
boolean isDirectory = file.isDirectory();

javadoc

中详细说明

Answer 3

这很简单。

String path = "..."; // Whatever the path may be
File file = new File(path);

if (file.isDirectory()) {
   // The path exists and it is a directory
   if (file.canWrite() {
       // The directory is writable
   } else {
       // The directory is not writable
   }
} else {
   // The path is not a directory, or it does not even exist
}

Answer 4

File I/O - Checking a File or Directory

Path path = ...;
if (Files.exists(path))
    /* the path exists */;

if (Files.isDirectory(path))
    /* the path exists and is a directory */;

if (Files.isWritable(path))
    /* the path is writable */;
