    Default How to create a driver program that invokes a class

    Create a class; call it Lab4a that will have one method called pull. This method does not return anything and requires no parameters.
     In the method, create three random integers in the range 1 to 7. The method will then display the three numbers to the terminal window.
     Now create a driver program, called SlotMachine, to invoke the pull method of the Lab4a class.
     As a refresher, you will have a main method in the driver class that will create an object of Lab4a and then use the only method of this object.
     In your driver program, invoke the roll method 10 times.
     See the back of this lab for an example of the output.

    This is what I have so far.

    Slot machine

    import java.util.Random;
    public class Lab4a
    public static void main (String[]args)

    Random pull=new Random();
    int num1;
    int num2;
    int num3;

    num2=pull.nextInt(7) +1;
    System.out.println ("Three random integers in the range 1-7 are : " +num1 + "," +num2 +"," +num3);

    Well for starters, do you have a question? Here is an observation. You don't have a pull method. You have an instance of Random assigned to a variable named pull. Do you know what a method is? And please enclosed your code between code tags. Go to advanced editing. Highlight the code and then click on '#' to wrap the code in code tags.

    Poor planning on your part does not constitute an emergency on my part
