How to create a Java Coffee Shop Program

This is a Java tutorial for creating a coffee shop program, the code below is how to set up the various java checkboxes and java radio buttons. In this tutorial, I utilized the Netbeans IDE which is great for developing Java GUIs in order to create something for the user to interact with. 

The Java GUI code is automated and all that is necessary is to add the logic for the buttons, ensuring that your java logic is how it is supposed to be will ensure of a successful program and is what the user is expecting. By using the simple java logic below I was able to create multiple programs including my java vending machine program as well as the coffee shop program. Both videos are down below for your viewing pleasure.

Remember in Java to comment there are several ways one is to place two forward slashes as seen below.

//Below we are creating a decimal format that will print out any remainder change with two decimal places. 

       DecimalFormat df = new DecimalFormat("0.00");

//Below are the variables we will be using

        double total;

        double subtotal = 0;

        final double TAXRATE = .08;

        double tax;


 //our radio buttons are next

        if (radCoffee.isSelected()){

            subtotal = subtotal + 1;

        }else if (radCap.isSelected()){

            subtotal = subtotal + 1.25;

        }else if (radTea.isSelected()){

            subtotal = subtotal + 1;


        //these are our checkbox buttons

        if (chkBag.isSelected()){

           subtotal = subtotal + 1.25;

        }if (chkCro.isSelected()){

           subtotal = subtotal + 1.15;

The rest of this code and how to create these GUI's can be done with the videos below.
