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…
For this code in java, I'm stuck on an error im getting on line 21 and when the code works it should ask what you want to name the two players. I also want both of the players to draw 5 random cards from the deck and show what they are.

In this variation of the game, two six-sided dice are used instead of cards. The dice are rolled, and the player tries to beat the computer’s hidden total without going over 21. Here are some suggestions for the game’s design: Each round of the game is performed as an iteration of a loop that repeats as long as the player agrees to roll the dice, and the player’s total does not exceed 21. At the beginning of each round, the program will ask the user whether or not he or she wants to roll the dice to accumulate points. During each round, the program simulates the rolling of two six-sided dice. It rolls the dice first for the computer, and then it asks the user whether he or she wants to roll.

- WRITE A JAVA PROGRAM. Telco is a cellular telephone company that offers two types of service: standard and premium. Its rates vary, depending on the type of service. The rates are computed as follows: Calculate the amount due if given a service code (s or S means standard service; a service code of p or P means premium service), and the number of minutes the service was used. For the premium service, the customer may be using the service during the day and the night. Therefore, to calculate the bill, you must ask the user to input the number of minutes the service was used during the day and the number of minutes the service was used during the night. Input Description: There are service code (s, S, p or P) and usage amount u (u≥0). If the service code is p or P, then the usage has two types; day usage du(du≥0) and night usage nu(nu≥0).

In this assignment, you will implement a simple game in a class called SimpleGame. This game has 2 options for the user playing. Based on user input, the user can choose to either convert time, from seconds to hours, minutes, and seconds, or calculate the sum of all digits in an integer. At the beginning of the game, the user will be prompted to input either 1 or 2, to indicate which option of the game they want to play. 1 will indicate converting time, and 2 will indicate calculating the sum of digits in an integer. For converting time, the user will be prompted to input a number of seconds (as an int) and the program will call a method that will convert the seconds to time, in the format hours:minutes:seconds, and print the result. For example, if the user enters 6734, the program will print the time, 1:52:14. As another example, if the user enters 10,000, the program should print 2:46:39.
