Instructions The history teacher at your school needs help in grading a True/False test. The students’ IDs and test answers are stored in a file. The first entry in the file contains answers to the test in the form:TFFTFFTTTTFFTFTFTFTTEvery other entry in the file is the student ID, followed by a blank, followed by the student’s responses. For example, the entry:ABC54301 TFTFTFTT TFTFTFFTTFTindicates that the student ID is ABC54301 and the answer to question 1 is True, the answer to question 2 is False, and so on. This student did not answer question 9. The exam has 20 questions, and the class has more than 150 students. Each correct answer is awarded two points, each wrong answer gets one point deducted, and no answer gets zero points. Write a program that processes the test data. The output should be the student’s ID, followed by the answers, followed by the test score, followed by the test grade. Assume the following grade scale:90%–100%, A; 80%–89.99%, B; 70%–79.99%, C; 60%–69.99%,…

File encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will bea version of the first file, but written in a secret code.Although there are complex encryption techniques, you should come up with a simple one of your own. For example, you could read the first file one character at a time, and add 10 to the character code of each character before it is written to the second file.   Write a program that decrypts the file produced by the program in above.The decryption program should read the contents of the coded file, restore the data to its original state, and write it to another file.

Simple Encryption. Write a java program that reads from a file specified by the user and encrypt the content of the file using a simple shifting technique. Also, ask the user to input the shift size. Output the encrypted message to another file whose filename is also provided by the user. For example, Shift size: 1 Message read from the file: Hello Encrypted message: Ifmmp

If wrong answer this time will downvote it Create a class with a static main that tests the ability to resolve and print a Path: • Create an instance of a FileSystem class. • Resolve an instance of a Path interface from a directory path and filename. • Print the constructed Path with System.out.println() method. 2. Create a class with a static main that tests the ability to resolve and print a Path: • Create an array of Path class. • Instantiate instances of Path with absolute and relative paths. • Print the constructed elements of the array of Path class with System.out.println() method. 3. Create a class to test serialisation class that implements serializable, it should implement the following: • A static void method that serialises an object. • A static void method that deserializes an object. • A static main method that tests the two by moving an object from one to the other

In Exercise 11.20, you created a Connect Four game that enables two players to play the game on the console. Rewrite the program using a GUI program, as shown in Figure 12.25. The program enables two players to place red and yellow disks in turn. To place a disk, the player needs to click on an available cell. An available cell is unoccupied and its downward neighbor is occupied. The program flashes the four winning cells if a player wins, and reports no winners if all cells are occupied with no winners.

Write a Java GUI program using BufferedReader that asks the user to input the file to be opened. If said file exists, the program shows its first line text. It is given that you have myFile.txt in your working directory with the following text. Sample Output:

create a java method named clearDirectory(String name)a. This method should delete all of the files in the directory with the specifiedname. Hint: read the java.io.File documentation to see how you might list the files in a directory and then delete them.b. If a file cannot be deleted for some reason, throw an IOException with anappropriate message including the absolute path to the file.c. Rethrow any exceptions that might occur.

Can you plaese do these questions for me    Our users do not want to have to re-enter the price levels each time the app starts. Therefor,  we need to save the price levels to a file on disk – called levelsFile - and populate the levelsList with the file’s items when the app starts. Also, every time the user manipulates the values in levelsList, levelsFile needs to be updated accordingly. The easiest way is not to update the file, but to simply override it (create a new file) with the new values in levelsList (each time the user manipulates items in the list). Two new methods need to be created in the PriceChecker class. They are readLevelsFromFile() and writeLevelsToFile(). And then the Main Code Section must also be updated to use these methods in the object. Note: The changes required to the Main Code Section are supplied on the next slide, but you need to complete the skeleton code of the two newly mentioned methods (supplied on subsequent slides).   Add the purple code to your…

You will develop a client side and a Servlet program that will work with a database. 1. The client (front end) should have a title "NJIT Credit Union", centered. 2. The client should have a background color. 3. The client should have a text field with label 'UserID' where user will enter userID (integer) and a Submit button with text "Submit". 4. An unsuccessful authentication should have a message printed on the screen, in red, stating that "Your authentication has failed, please try again.” (no pop up message). At this point the text field should get cleared and ready to accept a new input. Your program should not exit. 5. A successful authentication should be followed by a message on the screen, in green, stating that "Your authentication is successful" (no pop up message). 6. There should be two other text boxes with label "Deposit" and "Withdraw" where user will enter an amount (you should accommodate for decimals). These two text boxes should only be enabled after successful…

Using JAVA, Create a File Menu in your GUI Add a file menu to your BulbGUI with options to open any file for reading (and displaying the file as in Project 2), and one to Quit the program. You will need a FileMenuHandler class to handle the events from the FileMenu. Be sure to use getAbsolutePath() when getting the file from the JFileChooser, not getName(). Handle Exceptions Create an exception called IllegalBulbException (by extending IlegalArgumentException as shown in the lecture) and have the constructor of the Bulb throw it. For our purposes, a Bulb is illegal if the wattage is less than 5. Use a try/catch statement to catch this exception in your program, and display the erroneous Bulbs to the console (do not put them in the ArrayList). Use ArrayLists Use an ArrayList to store the unsorted Bulbs. For this project, display only the unsorted bulbs in the GUI.
