I need a java program that consists of 2 files: one with the methods and the other one to display using JOptionpane a grocery receipt only. The file with the methods must contain: Quantity, Item#,.
There are several coding style issues that hurt the readability of this program:. The indentation is incorrect. Use your IDE's reformat function to correct it (for example Control Shift f in Eclipse).
The naming doesn't follow the convention: use camelCase for variable names. CamelCase is reserved for class names. The naming can be further improved.
In a ShoppingItem class, there's no need to prefix each field with 'item'. Drop that prefix, use simply name, price, and instead of qty, I suggest to spell it out as quantity. The same goes for all the setters and getters of this class. The parameterless constructor doesn't serve much purpose here. Why should a default ShoppingItem be a 'Fruit' with price = 100? This is unnecessary, I suggest to remove it. ShoppingList also has its own naming issues:.
Why call a Scanner instance 'keyboard'? A scanner is a scanner, input can come from anywhere, not necessarily the keyboard. So I'd call it a 'scanner'. It would make sense to make displayItem plural, as it's used to display a list of items. When iterating over the list of items, instead of calling the loop variable x, I'd call it item, more natural. Instead of this: ArrayList list = new ArrayList; Declare variables with their interface type: List list = new ArrayList; Also, in Java 7 and above, use the diamond operator: List list = new ArrayList; (Java 7 is the currently supported version, so you should use at least that or above.).
ECommerce Java Sample App Welcome to the Intuit Developer's eCommerce Java Sample App. This sample app is meant to provide working examples of how to integrate your app with the Intuit Small Business ecosystem. Specifically, this sample application demonstrates the following:. Implementing OAuth to connect an application to a customer's QuickBooks Online company. Syncing customer and service item data from the app's local database to the QuickBooks Online company. Processing a credit card payment to QuickBooks Online Payments. Create a SalesReceipt in the QuickBooks Online company.
Please note that while these examples work, features not called out above are not intended to be taken and used in production business applications. In other words, this is not a seed project to be taken cart blanche and deployed to your production environment.
For example, certain concerns are not addressed at all in our samples (e.g. Security, privacy, scalability). In our sample apps, we strive to strike a balance between clarity, maintainability, and performance where we can.
However, clarity is ultimately the most important quality in a sample app. Therefore there are certain instances where we might forgo a more complicated implementation (e.g. Caching a frequently used value, robust error handling, more generic domain model structure) in favor of code that is easier to read. In that light, we welcome any feedback that makes our samples apps easier to learn from. Table of Contents.
Requirements In order to successfully run this sample app you need a few things:. Java 1.7. A account. An app on and the associated app token, consumer key, and consumer secret. QuickBooks Java SDK (already included in the folder of the GitHub repo). Helper Files for the payments API (already included in the folder of the GitHub repo) First Use Instructions.
Clone the GitHub repo to your computer. Fill in your file values (app token, consumer key, consumer secret) by copying over from the keys section for your app. Running the code Once the sample app code is on your computer, you can do the following steps to run the app:. cd to the project directory. Run the command:./gradlew bootRun (Mac OS) or gradlew.bat bootRun (Windows).
Wait until the terminal output displays the READY message. Open your browser and go to `If you happen to be behind an http proxy you will need to create a file called gradle.properties in the root of the project and follow instructions on this for configuring gradle to use a proxy.
