- Music App 1. practise file I/O and exception handling; 2. practise String processing. Aim: Task: Create a Java application that transcripts a simple song score sheet. The program asks user for filename of a text file that contains a simple song score sheet in this format: Sample song score sheet 1, song1.txt: #simple song with assumed time signature = 4 d1mls202s 1mld2o2 d1rimlfls 301s1f1m1rld4 Lines beginning with a hash #' is a comment line. A song contains one or more lines of musical notes, d, r, m, f, s, l, tand also o meaning "Off" or rest. Each single character note is followed by a single digit integer in [1 – 4], denoting the duration of the note in number of beats. After transcription, the program outputs the melody on the screen as well as to another text file: Melody output 1, on screen AND in melody_song1.txt: #simple song with assumed time signature Do Me So- Off- So Me Do Re Me Fa| So-- Off = 4 Do- Off- | So Fa Me Re Do--- | The default time signature is 4 beats per…Focus on Basic file operations, exception handlingCreate and save a file of the number below as module6data.txt: 26O76-9185-4485-95-3483-64-76-4189083-99-698-790-32-49-898579-285619-93-21-238251-80l62-78-87128-730-45-7328-5O-7063-36-720-76-24-590-548335-388-1429-351727-61-4249833879-803384196-944671876-63-3693-82-68-2069-57-84-29-177736-89-946210-69-43Write a program in python that will a.

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
