Add a command to this chapter’s case study program that allows the user to view the contents of a file in the current working directory. When the command is selected, the program should display a list of filenames and a prompt for the name of the file to be viewed. Be sure to include error recovery in the program. If the user enters a filename that does not exist they should be prompted to enter a filename that does exist.

The first option accepts information from the user and then save that data to a file on disk. The second option loads all data stored on that file.PHONE DIRECTORYDescription: Create a phonebook directory that will store the contact numbers of N persons. Your program should allow the user to add, view, delete, and update the contacts in the phonebook. Note that one person can have multiple contact numbers. The program will stop when the user command is ‘X’. Program command and entry should not be case-sensitive. That means commands ‘I’ or ‘i’ and the name “Jacky” or “JACKY” are the same. Each contact number can be 7 digits or 11 digits only. The user should input a string containing the command, name, and contact number(s) (Limit the contact number of each person to three). This string should be broken down into fields in order to separate the different values and store them in their appropriate variables. Use linked list in the implementation. Your node must declare at least four instance variables. Program flow: Command> I Jacky 09211234567 Remarks: New contact has been added. Command> V Jacky Contact…
- The File class contains file input and output operations. In other words, you can use the File class to read and write content from and to files. True FalseThe Spring fork amateur golf club has a tournament every weekend. The club president has asked you to design a program. It contains the following menu: Select the task 1. Add new records 2. Read Records 3. End the program If the user enters 1, the program will read each players name and golf score as keyboard input, then save the records in a file names golf.dat If the user enters 2, the program reads the records from the golf.dat file and displays them. While the menu selection is not equal to 3, get the user selection. If the selection is 1, get the number of players in the tournament, open the output file. For each player, get the name and the score, and write them to the file. Close the file. If the selection is 2, open the input file, read the values from the file, display the values, close the file. If the selection is 3, exit the program. I already had a code written from before, but I'm having a hard time turning it into a menu driven code.
