How to check if a file exists in Java before working with it?

You can check if a file exists in Java before working with it using the exists() method from the File class.

Following an example:

import java.io.File;

public class CheckFileExistsDemo {
    public static void main(String[] args) {
        // Specify the path and name of the file
        String filePath = "C:\\path\\to\\your\\directory\\example.txt";

        // Create a File object
        File file = new File(filePath);

        // Check if the file exists
        if (file.exists()) {
            System.out.println("File exists: " + file.getName());

            // Perform your operations on the file here
            // ...

        } else {
            System.out.println("File does not exist.");
        }
    }
}

Replace the filePath with the actual path and name of your file. This code checks whether the file exists before proceeding with any operations. It’s a good practice to perform this check to avoid potential issues when working with files that may not be present.
