- For the code in java below it shows a deck of 52 cards and asks the name of the two players and makes both players draw five cards from the deck.

What I want to be added to the code if for the cards that have been used to be removed and replaced with the other cards in the deck and for the next round to begin with Player B picking a card and Player A picking two cards that equal the same value as Player B's card.

- Hello, I am using the Intro to Java programmming and data structures by Y. Daniel Liang. Our professor wants us to generate a random number in java between 1 and 100. Then prompt the user for a number between 1 and 4. Next, the program will determine if the number entered by the user is a factor of the random number. I feel like I have some parts of the code down pack but not all of it. Thus far I have: import java.util.Scanner;public class Module_Project3 { public static void main(String[] args) {Scanner input = new Scanner(System.in);int num1 = (int)(Math.random()*100+1);int num2 = (int)(Math.random()*100+1);int num3 = (int)(Math.random()*100+1);int num4 = (int)(Math.random()*100+1);arrow_forwardIn JAVA ASSIGNMENT DESCRIPTION: A half-life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half-life of about 6 hours in humans. Given caffeine amount (in mg) as input, output the caffeine level after 6, 12, and 24 hours. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:System.out.printf("After 6 hours: %.2f mg\n", yourValue); Ex: If the input is: 100 the output is: After 6 hours: 50.00 mg After 12 hours: 25.00 mg After 24 hours: 6.25 mg Note: A cup of coffee has about 100 mg. A soda has about 40 mg. An "energy" drink (a misnomer) has between 100 mg and 200 mg. THE CODE I HAVE SO FAR: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); double caffeineMg; // "double" supports floating-point like 75.5, versus int for integers like 75. caffeineMg = scnr.nextDouble(); System.out.printf("After…arrow_forward1- Write a complete Java program that prompts for and reads three quiz grades for each student in a class of four students.

In Winter the food options are on the top so in this series Our Top Chef Alain Ducasse Introduce a new meal called Cube Cake As the name suggests, this delicious meal is a cake in the form of a complete cube with secret ingredients from the chef's list. As it is a new chef's creation, you want to understand the ability to make Cube Cakes look exactly the same. For this, you need to write a plan that will calculate the similarities between the two Cube cakes provided. Each piece of cake can be displayed as an N-size cube where each cube cell contains lower case letters ('a' - 'z'). The similarity between the two Cube Cakes (each N size) is defined as the standard sub-cube of the same size found in the same area in both Cube Cakes. Two sub-cubes are considered normal if at least P% of the corresponding characters are equal. You need to find the S size of the largest sub-cube and the number of common sub-cubes of…arrow_forwardPlease help with # 17.
