One of the most frequent tasks carried out by a file system in an operating system is checking the existence of a directory or a file. In the form of library functions, most programming languages provide some level of file system accessibility. You will discover how to test an existing file or directory in Java in this post.

Checking/Testing the presence of a directory

The class provides useful methods on file. This example shows how to check a file’s existence by using the file.exists() method of File class.



// Importing required libraries
public class GFG {
    public static void main(String[] args)
        throws IOException
        // Creating object of file and providing it path
        File f = new File("C:\\Test\\GFG.txt");
        // Check if the specified file
        // Exists or not
        if (f.exists())
            System.out.println("Does not Exists");


The above code sample will produce the following result (if the file “java.txt” exists in ‘C:/Test’ drive).
