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…

Usage: mortgagepmt [-s] -r rate [-d downpayment] price In this assignment, you are asked to do a mortgage payment calculation. All information needed for this will be passed to the program on the command line. There will be no user input during the execution of the program. You will need a few pieces of information. The price of the home and the amount of the down payment. You will also need to know the interest rate and the term of the mortgage. To figure your mortgage payment, start by converting your annual interest rate to a monthly interest rate by dividing by 12. Next, add 1 to the monthly rate. Third, multiply the number of years in the term of the mortgage by 12 to calculate the number of monthly payments you’ll make. Fourth, raise the result of 1 plus the monthly rate to the negative power of the number of monthly payments you’ll make. Fifth, subtract that result from 1. Sixth, divide the monthly rate by the result. Last, multiply the result by the amount you want to borrow.…

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

Finish this program from the code posted below! Note: There should be two files Main.py and Contact.py You will implement the edit_contact function. In the function, do the following: Ask the user to enter the name of the contact they want to edit. If the contact exists, in a loop, give them the following choices Remove one of the phone numbers from that Contact. Add a phone number to that Contact. Change that Contact's email address. Change that Contact's name (if they do this, you will have to remove the key/value pair from the dictionary and re-add it, since the key is the contact’s name. Use the dictionary's pop method for this!) Stop editing the Contact Once the user is finished making changes to the Contact, the function should return.
