The generator.nextInt(6) provides a random number between 0 and 5. We need a number from 1 to 6. Therefore we use generator.nextInt(6)+1 (that creates 1 out of 0, 2 out of 1 and so on).
We do it twice because we roll two dice. We sum them since we need the sum of the values.
This is a Hungarian accent.

Hi @otariglonti3651, thanks for your question!

Let's break down the code `int dice = generator.nextInt(6)+1 + generator.nextInt(6)+1;`.

Here, `generator.nextInt(6)` generates a random number from 0 to 5. By adding 1 (`+1`), we rescale the range to be from 1 to 6, which emulates a six-sided dice. As we are simulating the roll of two dice, the process is repeated a second time, hence you see `generator.nextInt(6)+1` twice.

The final outcome in `dice` will be the sum of two numbers, each between 1 and 6, thus simulating the total value from the roll of two dice.

Also, you have a good ear! I am indeed Hungarian. Thanks for your attention to detail and for tuning in to my videos. Happy coding!

I'm glad you like this video. In some days you can have the 2nd one as well. It will be uploaded to Duckademy, so you can download it from http://www.duckademy.com/course/java-programming

Hello @mustafakahkashan6609! Thank you for your patience and loyalty. We're absolutely thrilled to hear about your interest in our Java programming tutorial. Our team is working hard on the second video and we will upload it soon. We aim to ensure that our tutorials remain comprehensive, clear, and helpful, which sometimes take a bit longer. Remember, "Rome wasn't built in a day", and neither is good code. Stay tuned for the next part in our series focusing on a deep dive into switch statements, fighting rounds, and develop our game further. Thanks again for your support!

It's a good question. Java is an object-oriented language, therefore almost everything is an object or has some interconnection with the objects. You first create a Scanner object, and then it helps you read from the input. It allows you some flexibility as well (you can use Scanner for reading files as well) but it has its drawbacks.

Great question @cyborgsmurf6446, and a common one too! It's indeed true that Java requires a little more code for input as compared to languages like QBasic or others. The main reason for this is that Java has been designed to be a highly object-oriented language. This ultimately provides more flexibility and more precise control to the programmer.

Consider the Scanner class in your example. Yes, it needs to be imported and instantiated before using, but it also comes packed with a full suite of methods tailored for different types of inputs, like nextInt(), nextLine(), etc. With these, you can control how your program reads inputs in much more granular fashion.

On the other hand, QBasic's INPUT function, while more straightforward, is not as flexible when it comes to dealing with different types of inputs.

In summary, while Java might require more line of codes for this specific instance, the trade-off is the increased flexibility and control it offers which in the long run can make your programs much more robust and efficient. Don't let this overwhelm you - these aspects will start to make more sense and even come in handy as you dive deeper into Java programming!

Sorry to hear. You can download the source code for the exercises from Duckademy: https://www.duckademy.com/course/java-programming You will find it under Section 1. I hope this will help.

Hi @samalass466, sorry to hear about the issue you're facing. Could you please share more specifics? Information like what error messages you're receiving, at what point in the code it crashes, and your system details would be very helpful in identifying the cause so we can find a solution. Remember, Java is quite good at telling what went wrong and where. So copy-pasting the error message would be particularly helpful. Thank you!

Hi, thanks for your feedback. The complete course is here: https://www.duckademy.com/course/java-programming You can continue with Video 2 if you want, you will find it under Section 1.

We're thrilled to hear about your enthusiasm, @taiwoishola8779! Being a pro Java programmer is a powerful skill to have. Keep up with the course and don't hesitate to ask if you have any questions along the way. See you in the next video! Happy coding! ;)

Hi Geoffrey,
The name of a variable is to identify the thing it contains. It has to be easy to understand. For me and Scanner it is sc. If you prefer something else, you can choose it as you wish.
If you define your variables at the top, you may have to scroll back and forth from the code you are reading to the type of the variable while you are trying to understand a code. It's a principle to declare variable as you write the code: it will be as close to the usage point as possible.

Hi @ufotofu9,
Fantastic questions! When it comes to naming the Scanner class, you can really use any name that makes your code understandable to you and others. The name 'keyboard' for scanner is practical because it's an input tool, just like a physical keyboard! You could use 'sc', 'input', or any other name that makes sense. However, it’s best to keep it concise and meaningful.

Regarding your second question, the style decision to define variables exactly where they are to be first used is a common practice in Java. It's beneficial in that it minimises the variable's scope, keeping our program clean and avoiding unused variables. If you define all your variables at the top, they'd have a wider scope and could potentially lead to some unintended outcomes if not managed properly. Hope this helps! Keep your curiosity in programming. Happy coding!
