The program should calculate the sum of all the integers in the file, ignoring any non-numeric values. Requirements: The program should define a class named "FileSumCalculator". The class should have a method named "calculateSum" that takes a file path as a parameter and returns the sum of all the integers in the file. The method should handle any exceptions that might occur during the file reading and sum calculation. The program should print the sum of all the integers in the file to the console. Examples: 1. If the contents of the "input.txt" file are: 123 4 five 67 The program should print: Sum: 23

Copy the file to a new file called output.txtWrite the code that copies the input.txt file to anew file called output.txt.…If a file is set with the immutable flag, what security controls does this provide for the file?Prog 1. File Encryption: 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 each character in the input file into a code, and then writing the coded characters out to a second file. The second file will be a version of the first file but written in a secret code. In Notepad or something similar, you will create a file with text in it. It should be several lines long. Your program should read the file character by character and make some change to the character before writing that character to a second new encrypted file. See program 13-8 to see how to read and write one character at a time. You may come up with an encryption technique of your own or use something simple like adding 10 to the ASCII code of each character in the file before it is written to the second file.
