- Use a TextArea, and its setText() and append() methods to write an application that allows the user to select options for a dormitory room. Use CheckBoxes for options such as private room, Internet connection, cable TV connection, microwave, refrigerator, and so on. When the application starts, use a text area to display an appropriate message. After the user has selected the desired options, replace the message in the text area so it displays a running list of the user’s choices. Save the project as FXDorm.java.Use a TextArea, and its setText() and append() methods to write an application that allows the user to select options for a dormitory room.

After the user has selected the desired options, replace the message in the text area so it displays a running list of the user’s choices.Creating Enumerations In this section, you create two enumerations that hold colors and car model types. You will use them as field types in a Car class and write a demonstration program that shows how the enumerations are used. 1. Open a new file in your text editor, and type the following Color enumeration: enum Color {BLACK, BLUE, GREEN, RED, WHITE, YELLOW}; 2. Save the file as Color.java. 3. Open a new file in your text editor, and create the following Model enumeration: enum Model {SEDAN, CONVERTIBLE, MINIVAN}; 4. Save the file as Model.java. Next, open a new file in your text editor, and start to define a Car class that holds three fields: a year, a model, and a color. public class Car { private int year; private Model model; private Color color; 5. Add a constructor for the Car class that accepts parameters that hold the values for year, model, and color as follows: public Car(int yr, Model m, Color c) { year = yr; model = m; color = c; } 6. Add a display()…
- Create an application in Java that uses card layout with three cards. The first card - a login card - should have two text fields, one for username and other for password. There are two users - Bob and Fred - whose passwords are "mubby and "goolag" respectively. If Bob logs in, switch to a card - the bob card - that has a text field, a text area and two buttons. If the first button is pressed, get the text from the text field and append it to the text area. If the second button is pressed, return to the login card. If Fred logs in, switch to a card - the fred card - that has three buttons. If the first button is pressed, change the background color to green. If the second button is pressed, change the background color to red. If the third button is pressed, return to login card.Assume that class ArrayStack has been defined using the implementation in your textbook. Assume also that you start with the following code fragment: ArrayStack intStack; int data; intStack.push (4); #Statement A intStack.push (3); # Statement B intStack.push (2); # Statement C intStack.push (1); #Statement D Where should the statements: data intStack.peek): intStack.pop(): cout << data << endl; be placed into the code above to produce the following output: 4 The statements will be inserted as a group. Choose all locations required to produce the output.Java Questions - (Has 2 Parts). Based on each code, which answer out of the choices "A, B, C, D, E" is correct. Each question has one correct answer. Thank you. Part 1 - Which method do you need to invoke to display a frame (or a "form")? A. displayWindow = true;B. setVisible = true;C. setVisible(true);D. setDisplay(true);E. setShowForm(true); Part 2 - Which sets the frame (or a "form") width to 100 pixels and the height to 200 pixels? A. setSize(100, 200);B. setSize(200, 100);C. setDims(100, 200);D. setDimensions(200, 100);E. setWidth(100); setHeight(100);
- Write code that creates a Random object and then assigns a random integer in the range of 1 through 100 to the variable randomNumber.Write an application named, Lab14.java. This application will do the following: 1. Display an introductory message 2. Choose a random word from the file, wordlist.txt, and display it 3. Disguise the selected word, and display it 4. Ask the user whether to continue, i.e., whether to repeat steps 2, 3, and 4, or quit the application Once the user chooses to stop the application: 5. Display the total number of vowels hidden 6. Display the total number of consonants hidden 7. Display termination message The user will be asked whether to continue playing and will indicate that another game is to be played by answering ‘y’ or ‘Y’ in response to the question, “Want to play again?” asked by the program after displaying each chosen word and its disguised version. If the user’s response is any character other than ‘y’ or ‘Y’, the totals are displayed and then the application termination message is displayed. See examples below. About randomly choosing a word from the file, wordlist.txt, found on…Fix the following line of code to change the visibility of the btnExitProgram Button object so that you can view it when the program runs. btnExitProgram.Visibilty = Yes
