方法详细资料

lastIndexOfFolderSeparator

public static int lastIndexOfFolderSeparator(java.lang.String path)

getFileName

public static java.lang.String getFileName(java.lang.String path)

Extract the filename from the given path, e.g. "mypath/myfile.txt" -> "myfile.txt".

参数:

path - the file path

返回:

the extracted filename, or null if none

getFilePath

public static java.lang.String getFilePath(java.lang.String path)

Extract the path from the given path, e.g. "mypath/myfile.txt" -> "mypath/".

参数:

path - the file path

返回:

the extracted file's path, or null if none

getFileNameExtension

public static java.lang.String getFileNameExtension(java.lang.String path)

Extract the filename extension from the given path, e.g. "mypath/myfile.txt" -> "txt".

参数:

path - the file path

返回:

the extracted filename extension, or null if none

joinPath

public static java.lang.String joinPath(java.lang.String path,
                                        java.lang.String relativePath)

Join the given relative path to the given path, assuming standard Java folder separation (i.e. "/" separators);

参数:

path - the path to start from (usually a full file path)

relativePath - the relative path to apply

返回:

the full file path that results from applying the relative path

toCanonicalPath

public static java.lang.String toCanonicalPath(java.lang.String path)

Normalize the path by removing the ".." and "." from path.

The result is convenient for path comparison. For other uses, notice that Windows separators ("\") are replaced by simple slashes.

参数:

path - the original path

返回:

the normalized path

isRelativePath

public static boolean isRelativePath(java.lang.String path)

Return whether the path is a relative path which start with "." or "..".

参数:

path - the given path

返回:

the relative path
