Create functional tests where arguments are given, use a parameterized test.
testSimpleInit(size): the first constructor works as expected.
getTiles shows suitable values.
The edges of the board (the smallest and biggest conceivable values) are accessible and contain the values that they have to (BASE_TILE_SCORE).
testCustomInit(x, y, expected): the second constructor works as expected.
On positions where values smaller than three were passed, the board contains the value BASE_TILE_SCORE.
If you pass an array to the constructor and later modify a value in it, the respective tile retains the originally passed value.
If you modify an element in the return value of getTiles(), and get the value of the respective tile again, this newly received content has to be the originally set value.
testMoves(): take four or five steps and check that the board’s contents are changed just right.
Include a step that tries to move to the x coordinate Integer.MIN_VALUE and another one that moves to…
Define the Circle2DYourLastName class that contains: Two double data fields names x and y that specify the center of the circle withgetter methods. A double data field radius with getter method. A constructor that creates a circle with specified x, y, and radius. A method findTypeOfIntersection to determine and return types ofintersection as string (contained, overlap, or separate).Design a user class that prompts the user to enter the coordinates of the center andradius of two circles and displays the type of intersection. Allow the user to repeat yourprogram using a ConfirmDialog Box.
Complete the Car class by creating an attribute purchase_price (type int) and the method print_info() that outputs the car's information.
Ex: If the input is:
2011 18000 2018
where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, then print_info() outputs:
Car's information: Model year: 2011 Purchase price: 18000 Current value: 5770
Note: print_info() should use three spaces for indentation.

Every solid will have a volume. The method volume will be polymorphic. A solid has faces, vertices and edges. A flat-surface solid also has a variable called side which represents the length of the side. A curved-surface solid also has a radius. A Cube is a FlatSurfaceSolid. A cube has 6 faces, 8 vertices and 12 edges. It will have a side. A Sphere is a CurvedSurfaceSolid. It has 1 face, 0 vertices and 0 edges. It will have a radius. Create an ArrayList of solids (driver file named YourLastNameCISC231Q1.java). The arraylist will have 4 elements – 2 cubes (one with side length 3 and another will side length 4) and 2 spheres (one with radius 3 and another with radius 4). Create a driver class to instantiate an array of solids and display the details of each solid along with the volume of each solid.arrow_forward

Conditions for this method to return false are given in the code. public boolean canMove(int x, int y, int destX, int destY, Side s){ /* TODO write a method that checks if a piece at coordinates x,y can move to coordinates destX,destY Conditions for false: - Origin or destination coordinates are outside the board - Piece at origin is null - If source and destination coordinates are the same - Piece at origin is not of the same side as s - You can check this using piece.getSide() - Piece cannot move to the destination by piece movement rules - You should check this using Piece.canMove(destX,…arrow_forwardRules: Corner cases. By convention, the row and column indices are integers between 0 and n − 1, where (0, 0) is the upper-left site. Throw an IllegalArgumentException if any argument to open(), isOpen(), or isFull() is outside its prescribed range. Throw an IllegalArgumentException in the constructor if n ≤ 0. Unit testing. Your main() method must call each public constructor and method directly and help verify that they work as prescribed (e.g., by printing results to standard output). Performance requirements. The constructor must take Θ(n^2) time; all instance methods must take Θ(1)Θ(1) time plus Θ(1)Θ(1) calls to union() and find().arrow_forward
- Sally and Harry use two separate compareTo methods for a class they're developing jointly.

Finally, as you loop through the items the product table must be update because as products are sold the onhand field in the products table must be updated. When multiple tables are to be updated with related data, you should wrap it into a DMBS transaction.
