File getCanonicalFile() in Java

getCanonicalFile(): This method is available in the java.io.File class of Java.

Syntax:

File java.io.File.getCanonicalFile() throws IOException

This method returns the canonical form of this abstract pathname.

Parameters: NA

Returns: The canonical pathname string denoting the same file or directory as this abstract pathname.

Throws:

1. IOException - If an I/O error occurs, which is possible because the construction of the canonical pathname may require file system queries.

2. SecurityException - If a required system property value cannot be accessed, or if a security manager exists and its java.lang.SecurityManager.checkRead method denies read access to the file.

Approach

Java

import java.io.File;
import java.io.IOException;

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

        String pathname = "D:\\hello.txt";
        File file = new File(pathname);

        try {
            System.out.println(file.getCanonicalFile());
        } catch (IOException e) {

            System.out.println("Error occured");
        }
    }
}

Output:

D:\hello.txt
