Programming Assignment 6: SwapPoints
Objective: To write two missing functions that manipulate objects, to complete a given program.
- Please complete this SwapPoints program. so it produces the sample output shown at the end of the program, without changing the main method. Make sure to follow the instructions in the comments of the program. So your job is to write the two functions below, which are missing from the program:
- inputNewPlayerLocation: to input (x,y) coordinates from user (using Scanner), then return a Point object with those coordinates.
- swapPoints: to swap the coordinates of two Point objects. (Hint: To keep the main function's reference variables relevant, you can't swap Point objects entirely. You need to change the x and y coordinates inside the Point objects.)
/* Here is the Sample Output your completed program should produce:
Welcome, new player. Please enter your coordinates:
x: 5
y: 7
Welcome, new player. Please enter your coordinates:
x: 10
y: 15
Player1 location: (5,7)
Player2 location: (10,15)
Player 1 and Player 2 have swapped locations!
Player1 location: (10,15)
Player2 location: (5,7)
Welcome, new player. Please enter your coordinates:
x: 20
y: 30
Welcome, new player. Please enter your coordinates:
x: 3
y: 1
Player1 location: (20,30)
Player2 location: (3,1)
Player 1 and Player 2 have swapped locations!
Player1 location: (3,1)
Player2 location: (20,30)

- Topics: User-defined functions, list, string, docstringProblem Statement: This program finds the unique letters from a given string and printsthe unique letters and their count. For example: word ‘LITTLE’ has ‘L’, ‘I’, ‘T’, ‘E’ are theunique letters.Lab Scenario:The program repeats until hits ‘n’. The program takes a user input of a string. The programfinds the unique letters in the string, add them in a list and displays the list and their count.Consider the following important points:1) You need to design a user-defined function named count_unique_letters whichtakes user word as parameter and returns the list of unique letters calledunique_letters in the given word.a. Hint: Iterate over each letter in user word, check if the letter is in the list, if notadd it to the list, otherwise continue to the next letter. A ‘in’ keyword can helpto determine if a character in the unique_letters list.b. You need to write a simple docstring for this function.2) Your program must have a main()...arrow_forwardmenu(): Takes no inputs and does not return a value. It prints the two options available to the user and asks them to enter a number corresponding to their desired option. It then asks the user for the required inputs and then calls the appropriate function and prints the return value with an appropriate message (see below). If the user enters a number corresponding to an invalid option, Invalid choice. should be printed and the program should end. When the program ends, Have a nice day! should be printed to the user. If the user asks the program to solve an equation, then the program should ask the user to type in the equation (without spaces). If a solution is found, then print Solution found: followed by the solution as a list. If no solution was found, print No solution found. If the user asks the program to create an equation, then the program should ask the user to enter the number of tries, length of the equation and percentage for a number to have additional digits.

You also write the statements that make up the body of the loop. The source code file already contains the necessary variable declarations and output statements. Each theater patron enters a value from 0 to 4 indicating the number of stars the patron awards to the Guide’s featured movie of the week. The program executes continuously until the theater manager enters a negative number to quit. At the end of the program, you should display the average star rating for the movie. Instructions Ensure the file named MovieGuide.java is open. Write the while loop using a sentinel value to control the loop, and write the statements that make up the body of the loop to calculate the average star rating. Execute the program by clicking Run.

- Complete the Funnyville High School registration program where user is prompted for her full name and the program generates email id and temporary password. Sample run: generate_EmailID: This function takes two arguments: the user’s first name and last name and creates and returns the email id as a string by using these rules: The email id is all lower case. email id is of the form "last.first@fhs.edu". e.g. For "John Doe" it will be "doe.john@fhs.edu". See sample runs above. generate_Password: This function takes two arguments: the user’s first name and last name and generates and returns a temporary password as a string by using these rules. Assume that user's first and last names have at least 2 letters. The temporary password starts with the first 2 letters of the first name, made lower case. followed by a number which is the sum of the lengths of the first and last name (For example this number will be 7 for "John Doe" since length of "John" is 4 and length of "Doe" is...arrow_forwardUsing a Sentinel Value to Control a while Loop in Java Summary In this lab, you write a while loop that uses a sentinel value to control a loop in a Java program that has been provided.
