Path toAbsolutePath() method in Java with Examples
  • Last Updated : 03 Dec, 2019

The Java Path interface was added to Java NIO in Java 7. toAbsolutePath() method of java.nio.file.Path used to return a Path object representing the absolute path of this path object. If the path is already absolute then the method returns path else this method resolves this path in an implementation-dependent manner by resolving the path against a file system default directory. Depending on the implementation, this method may throw an I/O error if the file system is not accessible.

Syntax:

int toAbsolutePath()

Parameters: This method accepts nothing.

Return value: This method returns a Path object representing the absolute path.

Exception: This method throws following Exceptions:



  • IOError – if an I/O error occurs
  • SecurityException – In the case of the default provider, a security manager is installed, and this path is not absolute, then the security manager’s
  • checkPropertyAccess method is invoked to check access to the system property user.dir

Below programs illustrate toAbsolutePath() method:

                           + absPath);
