Problem specification:
There is a grid of NXN squares. We can easily determines how many different rectangles (squares are excluded) there are in the grid. For example, in a 3X3 grid, you can find 22 different rectangles, marked as the green rectangles. You can see that we did not count the red ones as they are squares. In this assignment, you will write a Java program that takes the value
of N as input and determines the total area of all the rectangles in the grid. Assume that the smallest squares in the grid have length 1. So a 3X2 rectangle will have an area of 6. For example, the total area of all the rectangles in the 3X3 grid is 66.…
For My Java class, this being my first programming class, I have been asked to complete the following to learn Loops. Next is arrays but I was hoping to get help understanding this first. Thanks
1-Design a program that asks the user to enter a series of positive numbers. The user should enter a negative number to signal the end of the series. After all the positive numbers have been entered, the program should display their sum.
2-The distance a vehicle travels can be calculated as follows: Distance = Speed x Time
Design a program that asks a user for the speed of a vehicle in miles per hour and how many hours it has travelled (Assume the two values are integers). Your program should then use a loop to display the distance the vehicle has traveled for each hour of that time period. (For example, entering 50 mph and 4 hours should produce output like: Hour 1: 50 miles, Hour 2: 100 miles, Hour 3: 150 miles, Hour 4: 200 miles. )
3-Design a program that uses nested loops to display a…
Use JAVA CARD GRAPHICS to create a card game in which the dealer shuffles the deck and deals 13 cards to the player. The player sorts her hand and says whether it includes the King of Hearts. Repeat 4 times so all the cards are dealt eventually. Internally, the player should return true or false without writing to the console. In response, the dealer should write on the console, "You won!" or "You loose again." Also create a unit test for the win and loose cases.

- f. A laborant in a laboratory does a number of antigen tests in one day. Write a program that simulates the number of antigen tests done in a day in a laboratory, displays the number of positives and negatives, and calculates the % of positives in one day. Your program needs to first generate a random number that will show the number of tests done in a day. One laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one). Then for each of the tests, your program needs to generate a random number to show whether they are positive or negative. In order to write this program, you need to have the following three functions used by the main function: test result (void): This function generates a test result. It should randomly return either one or zero. 1 means positive test result and 0 means negative test result. float positive percentage (int,int) : This function takes the total number of positives and the total number of tests and returns the % of positives.…arrow_forwardThe following code is to be done on Python: To play the UP Lotto, you buy a ticket that has five numbers in the range of 1–69,and a “UP Bonus” number in the range of 1–26. (You can pick the numbers yourself, or you can let the ticket machine randomly pick them for you.) Then, on a specified date, a winning set of numbers is randomly selected by a machine. If your first five numbers match the first five winning numbers in any order, and your UP Bonus number matches the winning Bonus number, then you win the UP LOTTO!, which is a very large amount of money. If your numbers match only some of the winning numbers, you win a lesser amount, depending on how many of the winning numbers you have matched. This data file has the list of the winning UP Lotto numbers that were selected between 2/2010 and 9/2023. Each line in the file contains the set of six numbers that were selected on a given date. The numbers are separated by commas, and the last number in each line is the UP Bonus number for…arrow_forward2. Write a program with a user interface which allows the user to enter 2 integers.
