Question

Please try to write the code with Project 1,2 and 3 in mind. And use java language, thank you very much.

Create an Edit Menu in your GUI

Add a second menu to the GUI called Edit which will have one menu item called Search. Clicking on search should prompt the user using a JOptionPane input dialog to enter a car make. The GUI should then display only cars of that make. You will need to write a second menu handler called EditMenuHandler.

Project3

Sorting an Array of Cars/ Displaying in a GUI/Creating a Class Create a class called Car to represent a car. It should have four private instance variables: A String for the make, a String for the model, an int for the year and an int for the mileage. The class should include a four-argument constructor and get and set methods for each instance variable. Override the method toString which should return the Car information in the same format as the input file (See below) Read the information about a car from a file that will be given to you on Blackboard, parse out the four pieces of information for the Car using a StringTokenizer, instantiate the Car and store the Car object in two different arrays (one of these arrays will be sorted in a later step). Once the file has been read and the arrays have been filled, sort one of the arrays by Make using Selection Sort. Display the contents of the arrays in a GUI that has a GridLayout with one row and two columns. The left column should display the cars in the order read from the file, and the right column should display the cars in sorted order The input file Each line of the input file will contain information about a car, with each piece of information separated by a comma. An example of the input file would be Toyota, Camry,2017, 41001 Subaru, Forester,2008,38913 If the line of the file does not have exactly four tokens, do not put it in the arrays; print it to the console Submitting the Project. You should have three files to submit for this project: Projectl.java CarGUI.java Car.java List of Cars Create a class called CarNode which has fields for the data (a Car) and next (CarNode) instance variables. Include a one-argument constructor which takes a Car as a parameter. (For hints, see the PowerPoint on "Static vs. Dynamic Structures".) public CarNode (Car c) t. . h The instance variables should have protected access. There will not be any get and set methods for the two instance variables Create an abstract linked list class called CarList. This should be a linked list with head node as described in lecture. Modify it so that the data type in the nodes is Car. The no-argument constructor should create an empty list with first and last pointing to an empty head node, and length equal to zero Include an append method in this class Create two more linked list classes that extend the abstract class CarList One called UnsortedCarList and one called SortedCarList, each with appropriate no-argument constructors. Each of these classes should have a method called add(Car) that will add a new node to the list. In the case of the UnsortedCarList it will add it to the end of the list by calling the append method in the super class. In the case of the SortedCarList it will insert the node in the proper position to keep the list sorted Instantiate two linked lists, and for every car read from the file, add it to the unsorted and sorted lists using the add method. You will end up with the first list having the cars from the input file in the order they were read, and in the second list the cars will be in sorted order. Display the unsorted and sorted cars in the GUI just as in project 1 Submitting the Project. You should now have the following files to submit for this project: Project2.java Car.java CarGUI.java CarNode.java CarList.java UnsortedCarList.java SortedCarList.java Create a File Menu in your GUI Add a file menu to your CarGUI with options to open a file for reading, and one to Quit the program. You will need a FileMenuHandler class to handle the events from the FileMenu. Create a jar file called Project3.jar and submit that to Blackboard by the due date for full credit.

Answer 1

As per HOMEWORKLIB RULES if students ask multiple programming questions then solve the first one.I have solved the first program.
Please let me know if you have any doubts or you want me to modify the answer. And if you find this answer useful then don't forget to rate my answer as thumps up. Thank you! :)
