How to get file path of a file using Java Code?

There are multiple ways to get the file path for a file in java, let's see a few examples,

Example 1: Using File class

import java.io.File;

/**
 * Get File Path using File class.
 */
public class FilePathExample {

    public static void main(String[] args) {
        File file = new File("data.txt");
        String filePath = file.getAbsolutePath();
        System.out.println("File Path: " + filePath);
    }
}

Output:

Example 2: Using File class

Path path = Paths.get("data.csv");
String absolutePath = path.toAbsolutePath().toString();

Example 3: Using ClassLoader

    public static void main(String[] args) throws URISyntaxException {
        ClassLoader classLoader = FilePathExample.class.getClassLoader();
        URL resource = classLoader.getResource("data.txt");
        if (resource != null) {
            Path path = Paths.get(resource.toURI());
            System.out.println("File path: " + path);
        } else {
            System.out.println("File not found");
        }
    }
