Not the purpose of the article but as I am a bit negative on Ruby, and I am neutral to positive on Java...

"Ruby is so much better than Java! Look at how you open a file in Java (shows you 30 lines) vs. Ruby! (2 lines)"

Ruby Example.

================

  begin
    File.open("/path/to/your/file.txt", "r") do |file|
      file.each_line do |line|
        puts line
      end
    end
  rescue Errno::ENOENT
    puts "File not found"
  rescue Exception => e
    puts "An error occurred: #{e.message}"
  end

Java Example, one line less than Ruby ( no imports shown but could also be required for external Gems )

================

  public class Main {
      public static void main(String[] args) {
          String filePath = "/path/to/your/file.txt";
          try (Stream<String> lines = Files.lines(Paths.get(filePath))) {
              lines.forEach(System.out::println);
          } catch (IOException e) {
              e.printStackTrace();
          }
      }
  }
