Chapter 3, Problem 7E
Select Show Code Pad from the View menu. Create a Number Di spl ay object with limit 6 in the Code Pad by typing
Then call its getValue, setValue, and increment methods in the Code Pad (e.g., by typing nd.getValue()). Note that statements (mutators) need a semi colon at the end, while expressions (accessors) do not. The call to setValue will need to include a numerical parameter value. Use the recorded method calls in the Terminal window to help you with the correct way of writing these method calls.

Assignment
First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects).
Then create a new Java application called "Parser" (without the quotation marks) that uses methods to:
Get a comma-delimited String of integers (e.g. "4, 8, 16, 32") from the user at the command line and then convert the String to an ArrayList of integers (using the wrapper class) with each element containing one of the input integers in sequence
Print the integers to the command line, using a for loop, so that each integer is on a separate line
BE SURE TO INCLUDE THE REQUIRED COMMENTS AND DOCUMENTATION AS WELL AS THE OUTPUT FROM MULTIPLE PROGRAM RUNS AS A COMMENT BLOCK AT THE BOTTOM OF YOUR SOURCE CODE FILE. See Grading Rubric.

This is a fairly easy labworkthat is more about getting used to synchronized online learning. You are expected to:• Draw two rectangles.• Both of them should be filled using GradientPaint() function of AWT. (Check out itsfunction definition that is listed below.)• The first gradient should be parallel to the diagonal of the first rectangle. The colorgradient should not be repeated (acyclic).• The second gradient should be horizontal. The color gradient should be repeated forthis one (cyclic).• You are free to choose the colors but other than that your output should be similar tothe example screenshot given below.arrow_forwardTrue or False?

- canMove(int x, int y, int destX, int destY, Side s): This method returns true if the player of color s can move the piece at coordinates (x,y) can move to coordinates (destX, destY) on the board in its current state. This means that here you do need to consider this piece’s interaction with other pieces on the board. 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_forwardWrite the following function that draws a line from point (x1, y1) to (x2, y2) with color (default to black) and line size (default to 1).def drawLine(x1, y1, x2, y2, color = "black", size = 1):arrow_forwardExercise 2: The intersection method computes the intersection of two rectangles- that is, the rectangle that would be formed by two overlapping rectangles if they were drawn, as shown at right. You call this method as follows: Rectangle r3 = r1.intersection (r2); Write a program IntersectionPrinter that constructs two rectangle objects, prints them as described in Exercise 1, and then prints the rectangle Intersection object that describes the intersection. Then the program should print the result of the intersection method when the rectangles do not overlap. Add a comment to your program that explains how you can tell whether the resulting rectangle is empty. The random class implements a random number generator, which produces sequences of numbers that appear to be random. To generate random integers, you construct an object of the Random class, and then apply the nextInt (50) gives you a random number between 0 and 49. Use the Random class to construct the two rectangle objects.arrow_forward

- IN JAVA LANGUAGE Write an ATM class with an ArrayList of Account objects as an attribute. In the constructor, add 3 Account objects to your ArrayList. They can all have a start balance of $100 and an annual interest rate of 0.12. Include two methods, menu and makeSelection as outlined below. Please note that since both methods get user input, create a Scanner attribute to use in both. menu method This method does not have any parameters and does not return a value. It should: Get the account number from the user. This corresponds to the index of the items in the ArrayList. Since there are 3 elements in your ArrayList, you are going to ask them for a number between 1 and 3, but keep in mind that the indices of the ArrayList are 0-2, so you'll have to adjust the value you get from the user accordingly. Present the user with a main menu as shown below: Get their menu selection Call the makeSelection method, passing it the account index obtained in step 1 and the menu selection…arrow_forwardJava Script There is a single operator in JavaScript, capable of providing the remainder of a division operation. Two numbers are passed as parameters. The first parameter divided by the second parameter will have a remainder, possibly zero. Return that value.
