Java Code Example 1 - Get File Size

import java.io.File;

public class GetFileSizeExample2 {
    public static void main(String[] args) {
        String fileLocation = "D:\\SimpleSolution\\logo.png";
        File file = new File(fileLocation);
        if(file.exists()) {
            long fileSizeInBytes = file.length();
            double fileSizeInKiloBytes = fileSizeInBytes / 1024.0;
            double fileSizeInMegaBytes = fileSizeInKiloBytes / 1024.0;
            double fileSizeInGigaBytes = fileSizeInMegaBytes / 1024.0;

            System.out.println("File size: " );
            System.out.println(fileSizeInBytes + " bytes");
            System.out.println(fileSizeInKiloBytes + " KB");
            System.out.println(fileSizeInMegaBytes + " MB");
            System.out.println(fileSizeInGigaBytes + " GB");
        } else {
            System.out.println("File does not exists.");
        }
    }
}
