Path toAbsolutePath() method in Java with Examples

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: 

Program 1:

Java

// Java program to demonstrate
// java.nio.file.Path.toAbsolutePath() method

import java.io.IOException;
import java.nio.file.Path;
import java.nio.file.Paths;

public class GFG {
    public static void main(String[] args)
    {

        // create object of Path
        Path path = Paths.get("\\temp\\Spring");

        // call toAbsolutePath() to get
        // absolute path
        Path absPath = path.toAbsolutePath();

        // print absolute path
        System.out.println("Absolute Path: "
                           + absPath);
    }
}

Output:

Program 2:

Java

// Java program to demonstrate
// java.nio.file.Path.toAbsolutePath() method

import java.io.IOException;
import java.nio.file.Path;
import java.nio.file.Paths;

public class GFG {
    public static void main(String[] args)
    {

        // create object of Path
        Path path = Paths.get("Program Files\\Java");

        // call toAbsolutePath() to get
        // absolute path
        Path absPath= path.toAbsolutePath();

        // print absolute path
        System.out.println("Absolute Path: "
                           + absPath);
    }
}
