how to generate a 3 random numbers between 1 and ten and then calculate the sum in java

Firstly, welcome to the forums.

While we are primarily here to help people with their Free Code Camp progress, we are open to people on other paths, too. Some of what you are asking is pretty trivial in the Free Code Camp context, so you might find that if you’re not getting the instruction and material you need in your current studies, the FCC curriculum will really help you get started. At a modest guess I’d say investing a 4-5 hours working through the curriculum here will really pay off. You can find the curriculum at https://www.freecodecamp.org/learn.

With your current questions, we don’t have enough context to know what you already know or don’t know, so it is impossible to guide you without just telling you the answer (which we won’t do).

It is pretty typical on here for people to share a codepen / repl.it / jsfiddle example of what they have tried so that anyone helping has more of an idea of what help is actually helpful.

Please provide some example of what you’ve tried and I’m sure you’ll get more help.

Happy coding :slight_smile:

sorry for this but this is my first code :upside_down_face:
but I can write what Ive written so far

That would help.

import java.util.Random;

public class Main
{
    public static void main(String[] args)
    {
        int min=0;
        int max=10;
        int range=max-min+1;
        int sum=0;
        Random rand=new Random();
        for (int i=0; i<3 ; i++)

        {
            System.out.println(Math.round(Math.random()*10) +1);
        }

    }
}

what I find it very hard is to calculate summing for this three generated numbers ,

I don’t understand what these variables are for.

This loop should probably do some sorbet of adding/suming? Though you probably don’t need it for 3 values.

Also, I’m not sure what the print line is for?

Instead of printing the value, you need to do something with it. You’re going to need a variable for your sum.
