double variable help

[jaune]

I'm modifying an already coded thing. It's just small. It computes the average of num1 and num2. I want to add a num3 that the user inputs manually after being asked by the program then to find the average of all 3 numbers. I have some code down but it's not working and I can't figure out how to fix it.

Here is the code by the way:

import java.util.Scanner;
public class Average3
{
    public static void main(String[] args)
    {
        Scanner k = new Scanner(System.in);
        //  Create integer variables named num1 and num2    
        int num1 = 75;
        int num2 = 137;
        int num3 = 
        System.out.print("Please input the value of num3: ");
        double num3 = k.nextDouble();
    
        // Compute the average of num1 and num2
        double.class average =(num1+num2)/2.0;

        // Output the result
        System.out.println("The average of "+num1);
        System.out.println("and "+num2+" is "+average);
    }
}

it's not working

Please explain.
Copy and post the console from when you execute the code and add some comments describing any problems.

If there are error messages, copy the full text and paste it here.

int num3 =

That is an invalid statement. As num3 is defined later, I don't think you need that line.

To find the average of 3 numbers, you need to sum these and then divide by 3.
