- 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%,…arrow_forwardWrite a program to create a class students having name, id, age. Create a file “student.txt” and open in append mode. Write the detail of 3 students into a file and read the data from the file and display on screen. Also copy content of this file into another file.arrow_forwardFor this exercise, you will create 2 classes: InputOutput class and AddNumbers class. ⦁ InputOutput Class: write a program that carries out the following tasks:⦁ Create an object of type PrintWriter and that writes into a file with the name greeting.txt.⦁ Print the message “Hello, world!” on the file.⦁ Close the file.⦁ Open the same file again.⦁ Read the message into a string variable (hint: use nextLine() method to read the text).⦁ Print the message on the screen. ⦁ AddNumbers Class: write a program that asks the user to input four floating-point numbers. Add all correctly specified values and print the sum when the user is done entering data. Use exception handling to detect improper inputs. For example, the user might enter letters instead of numbers. In this case, use the exception handling mechanism to print a proper message. (hint: use InputMismatchException) Don’t forget to import java.util.*.arrow_forward
- Write a program that opens a file me.txt and write your first name followed by a space followed by your last name, then your major on the second line. If the file does not exist, create it. If the file exists, have the file's contents be erased before writing your name. Be sure to close the file after. Example: Barack Obama Political Science Majorarrow_forwardImplement (in Java) a console application for writing data to a sequential text file with a formatter class in Java : a. Implement createFile() method – To open/create a new file named as ‘mec.txt’ with explanations of the methods involved. b. Implement writeRecord() method – User enter the employee name, employee id, gross salary, tax rate, income tax and net salary from the keyboard and write/add these values to the file ‘mec.txt’ with explanations of the methods involved. The input fields must be validated as necessary. c. Implement closeFile() method – Close the file with explanations of the methods involved.arrow_forwardWrite a program that prompts the user to enter the numberof students and each student’s name and score, and finally displays the name ofthe student with the highest score. Use the next() method in the Scanner classto read a name, rather than using the nextLine() method.arrow_forward
- Place the CashRegister calss in a file called cashregister.py and write following test code in the cell below. a Complete following test code: Import all methods of CashRegister class Write a test function to test the getTotal() and getCount() methods as it follows. add 5 items. undo the last item. add 3 more items. undo the last item after your test has done all of the above, print an statement for expected total price and total count. call the getTotal() and getCount(). (the result must be equal to the previous part) class CashRegister: def __init__(self): self._itemCount=0 self._totalPrice=0.0 self._taxPercent=13 def addItem(self,price): self._itemCount=self._itemCount+1 self._totalPrice=self._totalPrice+price def getTotal(self): return self._totalPrice def getCount(self): return self._itemCount def clear(self): self._itemCount=0 self._totalPrice=0 def updateTaxRate(self,newTaxPercent): if…arrow_forwardCreate a text file of names, (3 names per line, 5 lines in total) followed by an age for each name. Go through the file and sum the ages. Create an output file with each persons name followed by age and then a line at the end of the output file that says “sum of all ages is: x”. Simple Java programming. Should include things like bufferedReader, fileReader, printWriter, fileWriter, file close, try-with-resources, Scanner, catch/try, etc. Include Java file and txt file. Thank you.arrow_forwardcreate a class named FileUtils. Add a method static void copyFile(String source, String destination) method that copies the source file to the destination location. For example, if called as copyFile(“a.txt”, “b.txt”) the contents of the file “a.txt” would be copied into the file “b.txt.”a. You must write the code to copy the file using java.io.* classes (e.g. File, FileInputStream, FileOutputStream, etc.).b. Do not assume that the files will contain only text.c. You should try to copy efficiently (i.e. not a single byte at a time).d. It is suggested that you test your method by copying the provided files from the input directory to the output directory in your project.e. The method should rethrow any exceptions that may occur.arrow_forward
- Write a Java program that opens a file and counts the whitespace-separated words in that file. You may obtain the name of the input file either from the command line or via prompt and user input. Be sure to clearly document the method chosen. You may test your program using any number of text files; however, you must be sure to test your program using the Sample Text File provided at the end (excerpt.txt). Sample Text File There was nothing so VERY remarkable in that; nor did Alice think it so VERY much out of the way to hear the Rabbit say to itself, `Oh dear! Oh dear! I shall be late!' (when she thought it over afterwards, it occurred to her that she ought to have wondered at this, but at the time it all seemed quite natural); but when the Rabbit actually TOOK A WATCH OUT OF ITS WAISTCOAT- POCKET, and looked at it, and then hurried on, Alice started to her feet, for it flashed across her mind that she had never before seen a rabbit with either a waistcoat-pocket, or a watch to…arrow_forwardJAVA Problem – CycleFileOutput Revisit the Cycle class. Modify your application such that the properties will be written to a text file called “Cycle.txt” instead of to the screen. Directions Examine your application for the class called Cycle. Add an appropriate throws statement in the main method. Create a reference to a File class with the appropriate name of a text file (Cycle.txt). Use appropriate code to ensure that the text file exist. Output the values of the variables to the text file. Close the file. Note: Verify the contents were written to the text file using notepad (or any word processor). public class Cycle { // Declear integer instance variable private int numberOfWheels; private int weight; // Constructer declear class public Cycle(int numberOfWheels, int weight ) { this.numberOfWheels = numberOfWheels; this.weight = weight; } // String method for output public String toString() { String wheel = String.valueOf(this.numberOfWheels); String load =…arrow_forwardPart I Write a method that takes a celsius input from user and converts given value to other units of temperature, i.e. kelvin and fahrenheit. Part II Write a method that writes the given celsius input and its conversions to a file. Part III Write a method that reads the written temperature values from a file.arrow_forward
