import java.io.*;
import java.nio.file.Files;
import java.nio.file.Paths;

public class ExerciseRunner {
    public static void main(String[] args) throws IOException {
        Capitalize.capitalize(new String[]{"input", "output"});
        String expectedResult = new String(Files.readAllBytes(Paths.get("result")));
        String userOutput = new String(Files.readAllBytes(Paths.get("output")));
        System.out.println(expectedResult.equals(userOutput));
    }
}

and its output :

$ javac *.java -d build
$ java -cp build ExerciseRunner
