Chapter 10, Problem 5PC
Course Grades
In a course, a teacher gives the following tests and assignments:
- A lab activity that is observed by the teacher and assigned a numeric score.
- A pass/fail exam that has 10 questions. The minimum passing score is 70.
- An essay that is assigned a numeric score.
- A final exam that has 50 questions.
Write a class named CourseGrades. The class should have a GradedActivity array named grades as a field. The array should have four elements, one for each of the assignments previously described. The class should have the following methods:
| setLab: | This method should accept a GradedActivity object as its argument. This object should already hold the student’s score for the lab activity. Element 0 of the grades field should reference this object. |
| setPassFai1 Exam: | This method should accept a PassFailExam object as its argument. This object should already hold the student’s score for the pass/fail exam. Element 1 of the grades field should reference this object. |
| setEssay: | This method should accept an Essay object as its argument. (See |
| setFinal Exam: | This method should accept a FinalExam object as its argument. This object should already hold the student’s score for the final exam. Element 3 of the grades field should reference this object. |
| toString: | This method should return a string that contains the numeric scores and grades for each element in the grades array. |
Demonstrate the class in a program.

Project 5 - Magic Squares
Objectives
The objective of this project is to have students practice with two-dimensional arrays and loops.
Specifications
In this project, you will write code to determine if a two-dimensional array of ints is a Magic Square. For a two-
dimensional array of ints to be a Magic Square all of the following must be true:
1. The array must be square - in other words, the lengths of all rows and all columns must be the same.
2. The array must contain all integers from 1 to n*n, where n is the length of the rows and columns.
3. The sum of the numbers in each diagonal, each row, and each column must be the same.
You have been given two classes:
• MagicSquareTest.java - Contains JUnit test cases for the MagicSquare class. Your code must pass all these tests.
• MagicSquare.java - contains static methods to determine if a two-dimensional array of ints is a Magic Square:
o isMagicSquare() - returns true if a two-dimensional array of ints meets all the criteria to be a…
Menu Item
Description
Add Dog
1) Asks the user for all the state value information for a dog.
2) Checks if there is space in the array to hold the new dog.
3) Check that the dogld is not already used in the system.
4) Creates a new Dog object and adds it to the array if there is space. If the
array is full, print "Sorry... the Shelter is Full!".
Note: All new dogs have no home as yet (foundHome = false).
View all dogs
This menu option shows all dogs in the system. This includes dogs that have a
home and those that do not.
View all available dogs
Shows all dogs in the system, which have no homes as yet.
View a specific dog
1) Asks the user for a dogld.
2) Searches for a dog at the shelter with that dogld.
3) Displays the information of the dog associated with that dogld if found. If
the dog is not found, "There is no dog with that id.." must be displayed.

1. Create and array of objects named movies . Each of the objects in the array will represent a movie.Each object should have properties for:movie titlerelease yearrating (your rating 1 - 10)genres (an array of genres. eg ["Drama", "Mystery", "Sci-Fi", "Western"] )The array should contain at least 5 of movies you have seen (choose your own movies)You do not need to use JSON to create this arrayYou can use IMDB if you need help finding the info for your movie2. Now that digital format is taking over, we would like to add a property to each object for the format (“film” or“digital”). The property will be called format . Assuming that all movies in our data set where shot on film, use.forEach() to add the property and set a value of “film” for each movie.3. Use the .map() method to create an array of movie titles from our initial data set named movieTitles .4. Use the .reduce() method to find the highest and lowest rated movies in the data set. Store these objects invariables…

Create an array big enough to hold the numbers and store each number in the array as it's entered be sure to prompt the user for each number before it is entered you do not need to initialize the array. Hints: be sure to use a name constant when you declare the array (the number inside the bracket should be a named constant that you declare before the array declaration.) Use a for loop or while loop if you like to get each number from the user.

In the game of battleship a `~' character entry in the array represents ocean (i.e., not a ship), a `#' character represents a place in the ocean where part of a ship is present, and a `H' character represents a place in the ocean where part of a ship is present and has been hit by a torpedo. Thus, a ship with all `H' characters means the ship has been sunk. Declare a two-dimensional array that is 25 x 25 that represents the entire ocean and an If statement that prints "HIT" if a torpedo hits a ship given the coordinates X and Y. Create a text file of 25 line. Each line has 25 characters. ~ represents water and # represents part of a ship. This file is the battleship game board.

The application should use a two-dimensional int array to simulate the game board in memory. When the user clicks the New Game button, the application should step through the array, storing a random number in the range of 0 through 1 in each element. The number 0 represents the letter O, and the number 1 represents the letter X. The form should then be updated to display the game board. The application should display a message indicating whether player X won, player Y won, or the game was a tie.arrow_forward
