Assignment #1 Create a Java application whose main window contains a tabbed pane (look the Figure). The tabbed pane contains multiple components each of which is displayed on a separate tab. The application should be extendable so that new components can be added without modifying the code. The user is expected to design a new component as a separate class. Use the factory pattern plus other 0OP principles to support such a design. TabbedPaneDemo Tab 1 Tab 2 Tab 3 Tab 4 Panel #1 Does nothing at all

Create a C# application for MotorHub using Visual Studio. The application should be titled “MotorHub Car Inventory App”. It must consist of a car logo (see Figure 1). The application must allow the user to enter the car details and store them. Your application must consist of a class for handling the car details. The car details that you need to capture are the Inventory Number, Name, Model, Year, Mileage and Price. The class must also consist of a default constructor which initialises the public properties. The class must also contain a constructor which sets the properties to values received from the main form. The application should accept values from a user which will be typed into the textboxes. When a user enters the car details and clicks the “Add Car” button, a new Car object must be created and stored in an ArrayList. At the same time, a method must update the ListBox with the inventory number. This will allow the user to select an inventory number and the car details will…

Portfolio Instructions: You are working for a financial advisor who creates portfolios of financial securities for his clients. A portfolio is a conglomeration of various financial assets, such as stocks and bonds, that together create a balanced collection of investments. When the financial advisor makes a purchase of securities on behalf of a client, a single transaction can include multiple shares of stock or multiple bonds. It is your job to create an object-oriented application that will allow the financial advisor to maintain the portfolios for his/her clients. You will need to create several classes to maintain this information: Security, Stock, Bond, Portfolio, and Date. The characteristics of stocks and bonds in a portfolio are shown below: Stocks: Bonds: Purchase date (Date) Purchase date (Date) Purchase price (double)…
IN JAVA, PLEASE CREATE A RESERVATION AIRLINE SYSTEM AND MAKE SURE IT HAS THE FOLLOWING (PLEASE THE CODE IS FOR A RESERVATION AIRLINE SYSTEM) Three classes minimum At least one class must use inheritance At least one class must be abstract JavaFX front end – as you will see, JavaFX will allow you to create a GUI user interface. The User Interface must respond to events. If your application requires a data backend, you can choose to use a database or to use text files. Error handling - The application should be able to handle invalid data. Screenshots
Objectives: Use Javadocs to document a class and methods Design and write a Java class Use fields (instance variables) Write multiple constructors Write accessor methods Write mutator methods Use the this keyword Use string concatenation Round floating point numbers (using Math.round()) Use a Scanner object Description ProduceItem class For this project, you get to design and write a ProduceItem class that stores a description, cost and weight as fields. Include both a constructor without any parameters and one with parameters for the description (String), cost (double) and weight (double) (in that order). For the constructor without parameters, set the description to an empty string, the cost to 0.0 and the weight to 0.0. Include appropriate accessor and mutator methods (and label them with comments including the terms "accessor" or "mutator"). So that the test cases compile, name the accessor methods: getDescription() getCost() getWeight() Additionally, name the mutator methods:…
In Java programming. Write the method that will populate the properties of each object. Assume that you have read the data from a flat file into variables for each property in the class. customer = new_Customer (); inventory = new_Inventory (); orderHeader = new_OrderHeader (); orderDetail = new_OrderDetail (); invoice = new_Invoice (); shipment = new_Shipment (); Use one of the object names from above. Write the signature line for this method Write the code that will assign a variable value to one property in the selected object. Be sure variable names use proper naming convention.

Also include a displayInfo() method that displays each of the Book's data fields with explanations.Design a class named TextBook that is a child class of Book. Include a new data field for the grade level of the book. Override the Book class displayInfo() method to accommodate the new grade-level field.
in C# i need to Create an application named TurningDemo that creates instances of four classes: Page, Corner, Pancake, and Leaf. Create an interface named ITurnable that contains a single method named Turn(). The classes named Page, Corner, Pancake, and Leaf implement ITurnable. Create each class’s Turn() method to display an appropriate message. For example: The Page’s Turn() method should display You turn a page in a book. The Corner’s Turn() method should display You turn corners to go around the block. The Pancake's Turn() method should display You turn a pancake when it's done on one side. The Leaf's Turn() method should display A leaf turns colors in the fall.
