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 program to demonstrate 
// java.nio.file.Path.toAbsolute() 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 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); 
    } 
}
