OWrite a program that reads data from a file containing integers that ends with -999. Output the numbers that are divisible by 7 Output the numbers that are divisible by 11 Output the numbers that are not divisible by 7 or 11.
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.*.

Task: Loading data from files This exercise will require you to load some information from files and use it in your program. scene.txt contains a description of a series of shapes and colours to draw. You need to write code to read in the file data and draw the requested shapes in the correct colour. Each line in scene.txt will contain one of the following starting keywords followed by some data:  COLOUR followed by 3 values: R, G, B  CIRCLE followed by 3 values: X, Y, RADIUS  RECT Followed by 4 values: X, Y, W, H  LINE Followed by 4 values: X1, Y1, X2, Y2 CIRCLES are defined from the center. RECT's are defined from the top left. All values are space separated, and you can assume all input is correct (no errors). Please solve this program to draw the scene. I can't upload the file scene.txt, so I decide to screenshot a file for you. Subject: Java Programming
Requested files: InClass02.java, input.txt Maximum number of files: 6 Create a simple java program that reads all the content in a .txt file, the user will enter the filename to be opened. In this case, the file will contain multiple lines of student details with each line containing a single student detail. Your task is to then create a student class that models the firstname, lastname, year of birth and gender of every student. The student class should further be able to assign every student created with a student number using a class variable[format is 2022000X, X is a number such as 1,2..] and be able to calculate the age of each student. Within the driver class add all the students read from file into an ArrayList and then print the first and last student in the list. You are additionally expected to deal with most common exceptions(See samples below) [HINT: DO NOT PROVIDE A PATH BUT RATHER ONLY OPEN THE FILE WITH RELATIVE PATH/FILENAME] Sample run 1: Enter filename:…
Word Puzzle GameIn this assignment is only for individual. You are going to decode the scrambled word into correct orderin this game. One round of play is as follows:1. Computer reads a text file named words.txt2. Computer randomly picks one word in the file and randomly scrambles characters in the wordmany times to hide the word3. Computer displays the scrambled word to user with indexes and gives the user options to1. Swap two letters in word based on index given2. Solve the puzzle directly3. Quit the game4. If a player chooses to swap letters, the computer reads two indexes and swaps the letters. Thegame resume to step 3 with the newly guessed word. If the resulted word after swapping is thesecret word, the game is over.5. If a user chooses to solve directly, computer prompts the user to enter the guessed word. If it’scorrect, the game is over, otherwise goes to step 3.6. After game is over, display how many times the player has tried to solve the puzzle.The following is sample…
IN C++ VISUAL STUDIO Create two classes one to read data from file, and the other to write data into a file. The data can be about employees having information about employee name, id and designation. You must create a class for employee. There is a total of 3 classes in your program. In the second class, which is about file writing, you have to write data about 10 employees in file. You can get data from user. In reading class, you have to read information about a specific employee whose id is given by user. Finally write a function to show data about employees whose designation is “manager”.
