- Create a class(in JAVA) for FileHandling with following members Final and Static field named as “bookPath”, which holds the address for the file, i.e; “Data\book.txt” Final and Static field named as “authorPath”, which holds the address for the file, i.e; “Data\author.txt” Static method to write data in file. It takes two arguments: data and file path. Data is inserted at the end of the file while previous data remains. Data is single line to write in the file. Static method to read data from file. It takes file path and returns whole file data. Create Main class containing main method and show the working of FileHandling class without creating the object.Programming Problem 3 – CycleFileInput Revisit the Cycle class in Module 3. Modify your application such that the properties will be read from a text file called “Cycle.txt”. 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). Note: Cycle.txt was created in the previous assignment, CycleFileOutput. In your code, check that the text file does exist. Input the values from the file to memory. Close the file.How to code this assignment JSON objects. Hint: Work on the methods in the order they are found in the documentation below. def read_last_line(file_path: str)->str: """ Reads the last line of the file at the specified file path. The function returns the last line of the file as a string, if the file is empty it will return an empty string (""). :param file_path: A path to a file :return: The last line of the file """ def read(file_path: str)->str: """ Reads the entire file at the specified file path.

You have to create Person class (String name, int age) Please read the file and show the sum of all the numbers.Java Problem The teacher at a school needs help grading an exam with a number of True/False questions. The students’ IDs and test answers are stored in a file. The first entry of the file contains the answer to the test in the form: TTFTFTTTFTFTFFTTFTTF Every other entry in the file is the student’s ID, followed by a blank, followed by the students’ response. For instance, the entry: ABC54102 T FTFTFTTTFTTFTTF TF The student’s ID is ABC54102, answer to question 1 is True, the answer to question 3 is False. Also, the student did not answer question 2 and question 18. The exam has 20 questions. Here is the grading policy: each correct answer is awarded two points, each wrong answer get -1 point, and no answer gets 0 point. 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 (total points), followed by the test grade. Assume the following grade scale will be used: 90%-100%, A; 80%-89.99%, B; 70%-79.99%,…
- Write a class FileConverter with a constructor that accepts a String file name as its argument. It should store filename as its attribute (with a accessor getFilename(). The class should have the following methods: • createUpperCaseFile(): Accepts a String parameter targetFilename. It will open up both the file specified in class attribute filename and the method parameter targetFilename. Then it will convert all lines of the class attribute filename to upper case and write it to target file, line by line. • createRowCharCountFile(): Accepts a String parameter targetFilename. It will open up both the file specified in class attribute filename and the method parameter targetFilename. Then it will count the number of chars in each line of the class attribute filename and write it to target file line by line. The class must come with a main() method, which will create an object instance and generate two target files based on the source file, one all upper case, and another row char count.InputOutput Class: write a program that carries out the following tasks: o Create an object of type PrintWriter and that writes into a file with the name greeting.txt. o Print the message "Hello, world!" on the file. o Close the file. o Open the same file again. o Read the message into a string variable (hint: use nextLine() method to read the text). o 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.*.If an object cannot be found, it is generally better to throw an exception than return null. True False
- Assessment Description Honors Students: Complete this assignment according to the directions provided in the "Honors Addendum," located in Class Resources. This activity has multiple parts. All parts must be completed prior to documentation submission. Part 1: Reading and Writing Text Files. In this activity, you will learn how to read and write text files using non buffered and buffered File I/O classes, then learn how to parse a String into tokens using the String split() method, and finally, how to handle exceptions using various approaches. Part 2: Reading and Writing JSON Files. In this activity, you will learn how to read, write, and serialize JSON files to and from Java Objects. Refer to the instructions within "Activity 4 Guide" to complete the assignment. APA style is not required, but solid academic writing is expected. This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful…/** * The file path that is IOManager read and write an object from.

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
