In short: getPath () gets the path string that the File object was constructed with, and it may be relative current directory. getAbsolutePath () gets the path string after resolving it against the current directory if it's relative, resulting in a fully qualified path.
What is the difference between getpath() and getcanonicalpath()?
So, getPath() gives you the path based on the File object, which may or may not be relative; getAbsolutePath() gives you an absolute path to the file; and getCanonicalPath() gives you the unique absolute path to the file. Notice that there are a huge number of absolute paths that point to the same file, but only one canonical path.
What is the use of getabsolutepath?
The getAbsolutePath() method returns the pathname of the file after resolving the path for the current user directory — this is called an absolute pathname. So, for our previous example, file.getAbsolutePath() would return:
What is the difference between absolute and relative path in Python?
If the file object is created using an absolute path then the path returned is an absolute path. If the abstract pathname is already absolute, then the same pathname string is returned. If the file object is created using a relative path then the path returned is a relative path.

What is the difference between absolute path and canonical path in Java?
Absolute path defines a path from the root of the file system e.g. C:\\ or D:\\ in Windows and from / in UNIX based operating systems e.g. Linux or Solaris. The canonical path is a little bit tricky because all canonical path is absolute, but vice-versa is not true.
What is getAbsolutePath in Java?
The getAbsolutePath() method is a part of File class. This function returns the absolute pathname of the given file object. If the pathname of the file object is absolute then it simply returns the path of the current file object. For Example: if we create a file object using the path as “program.
What is file getPath in Java?
The getPath() method is a part of File class. This function returns the path of the given file object. The function returns a string object which contains the path of the given file object.
What is getCanonicalPath in Java?
The getCanonicalPath() method is a part of Path class. This function returns the Canonical pathname of the given file object. If the pathname of the file object is Canonical then it simply returns the path of the current file object. The Canonical path is always absolute and unique, the function removes the '.
What does getPath return?
Simply put, getPath() returns the String representation of the file's abstract pathname. This is essentially the pathname passed to the File constructor. So, if the File object was created using a relative path, the returned value from getPath() method would also be a relative path.
How do I find a file path?
Click the Start button and then click Computer, click to open the location of the desired file, hold down the Shift key and right-click the file. Copy As Path: Click this option to paste the full file path into a document. Properties: Click this option to immediately view the full file path (location).
What is a canonical path?
The canonical path is always an absolute and unique path. If String pathname is used to create a file object, it simply returns the pathname. This method first converts this pathname to absolute form if needed. To do that it will invoke the getAbsolutePath() Method and then maps it to its unique form.
How do I get the file path from the multipart file?
File , we can use the following APIs to get the file path of a file.file.getAbsolutePath() = path.toAbsolutePath()file.getCanonicalPath() = path.toRealPath()file.getParent() = path.getParent()
What is the use of Fileoutputstream in Java?

What is use of file class in java?
Java File class represents the files and directory pathnames in an abstract manner. This class is used for creation of files and directories, file searching, file deletion, etc. The File object represents the actual file/directory on the disk. Following is the list of constructors to create a File object.
What is import java IO file?
If you import java.io. * the compiler will look at all classes in the java.io package when it needs to find a class you are using. It will actually look for the . class files in the java\io directory (and in this directory path inside any jar files) on the classpath.
What is a file separator?
A file separator is a character that is used to separate directory names that make up a path to a particular location. This character is operating system specific. On Microsoft Windows, it is a back-slash character (), e.g. C:myprojectmyfilesome.
What is a canonical path?
The canonical path is always an absolute and unique path. If String pathname is used to create a file object, it simply returns the pathname. This method first converts this pathname to absolute form if needed. To do that it will invoke the getAbsolutePath() Method and then maps it to its unique form.
What is system getProperty user dir?
getProperty() is used to obtain the system property. This system property is specified by the key which is the parameter for the method. To obtain the current working directory, the key used is user. dir.
How do I find absolute path in Linux?
To obtain the full path of a file, we use the readlink command. readlink prints the absolute path of a symbolic link, but as a side-effect, it also prints the absolute path for a relative path. In the case of the first command, readlink resolves the relative path of foo/ to the absolute path of /home/example/foo/.
What's the difference between getPath(), getAbsolutePath(), and ...
In short: getPath() gets the path string that the File object was constructed with, and it may be relative current directory. getAbsolutePath() gets the path string after resolving it against the current directory if it's relative, resulting in a fully qualified path. getCanonicalPath() gets the path string after resolving any relative path against current directory, and removes any relative ...
Comparing getPath(), getAbsolutePath(), and getCanonicalPath() in Java ...
The getCanonicalPath() method goes a step further and resolves the absolute pathname as well as the shorthands or redundant names like “.” and “..“ as per the directory structure. It also resolves symbolic links on Unix systems and converts the drive letter to a standard case on Windows systems.. So for the previous example, getCanonicalPath() method would return:
How to get the current working directory in Java?
@indyaah infact this answer is wrong, there is a subtle difference between a user-working-directory and a current-working-directory of a system process (cwd); most of time the "user.dir" points to the cwd of a (java)process; but "user.dir" has different semantics and shall not be used to obtain the cwd of a java process; btw:there are more properties available to java process docs.oracle.com ...
Difference Between getCanonicalPath() and getAbsolutePath() in Java
The getCanonicalPath() and getAbsolutePath() methods belong to java.io.File class in Java. And these methods are basically used to get the path of a file object in the system’s directory structure.
File getAbsolutePath() method in Java with Examples
For Example: if we create a file object using the path as “program.txt”, it points to the file present in the same directory where the executable program is kept (if you are using an IDE it will point to the file where you have saved the program ). Here the path of the file mentioned above is “program.txt” but this path is not absolute (i.e. not complete).
What is the difference between getAbsolutePath and getCanonicalPath?
So, getPath () gives you the path based on the File object, which may or may not be relative; getAbsolutePath () gives you an absolute path to the file; and getCanonicalPath () gives you the unique absolute path to the file.
What does getAbsolutePath() do?
getAbsolutePath()fetches the path that the File was created with, but includes information about the current directory if the path is relative (/usr/bobstuff/../foo.txt)
How to get canonical path?
getCanonicalPath()gets the path string after resolving any relative path against current directory, and removes any relative pathing (.and .. ), and any file system links to return a path which the file system considers the canonical means to reference the file system object to which it points.
What is the function of getPath()?
As to when to use them. It depends on what you are trying to achieve. getPath()is useful for portability. getAbsolutePath()is useful to find the file system location , and getCanonicalPath()is particularly useful to check if two files are the same.
What does getPath() do?
getPath()gets the path string that the Fileobject was constructed with, and it may be relative current directory.
Does path consider the syntax of a component?
path does not really consider those issues or existence of any of the components, only the syntax of it.
Is the output of both paths the same?
While both paths refer to the same location, the output will be quite different:
What does getpath do?
Simply put, getPath () returns the String representation of the file's abstract pathname. This is essentially the pathname passed to the File constructor.
What is the getCanonicalPath method?
The getCanonicalPath () method goes a step further and resolves the absolute pathname as well as the shorthands or redundant names like “.” and “..“ as per the directory structure. It also resolves symbolic links on Unix systems and converts the drive letter to a standard case on Windows systems.
Why does getCanonicalPath throw IOException?
Unlike the last two methods, getCanonicalPath () may throw IOException because it requires filesystem queries. For example, on Windows systems, if we create a File object with one of the illegal characters, resolving the canonical path will throw an IOException: 3. Use Case.
How many methods does Java.io.File have?
The java.io.File class has three methods — getPath (), getAbsolutePath () and getCanonicalPath () — to obtain the filesystem path.
Does getCanonicalPath read the filesystem?
However, since getCanonicalPath () reads the filesystem, it comes at a performance cost. If we are sure that there are no redundant names or symbolic links and drive letter case is standardized (if using a Windows OS), then we should prefer using getAbsoultePath ().
Can a file have an infinite number of paths?
It's worth mentioning that a single file on the filesystem can have an infinite number of absolute paths since there's an infinite number of ways shorthand representations can be used. However, the canonical path will always be unique since all such representations are resolved.
What is the getcanonicalpath method?

If the given pathname is already absolute, then the pathname string is simply returned as if by the getPath () method. If the current abstract pathname is the empty abstract pathname then the pathname string of the current user directory (named by the system property) is returned. Else, this pathname is resolved in a system-dependent way.
