IN JAVA
The following program generates an error. Why?
public static void printSum(int num1, int num2) {System.out.print(num1 + num2);}public static void main(String args[]) {int y;y = printSum(4, 5); return 0;}
A. printSum() is missing a "return;" statement.
B. The values 4 and 5 cannot be passed directly to printSum()
C. main() has a return statement that returns the value 0
D. printSum() has void return type, so cannot be assigned to a variable
In 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();

- Write java program that will calculate the amount to be paid for electrical consumption. This problem is to handle electric billing for customers. The billing is depending on the type of the customer account. There are two types of customers account; i) fixed rate method and 2) variable rate method in the case of fixed rate method. The minimum monthly charge of RM20.00 is assessed if the consumption is less than or equal 100 kwh( kilowatt-hours). Otherwise, the rate of RM 0.22 per kWh is charged for the first 100 kWh and the rate of RM 0.33 per kWh is charged for the additional consumption. In the case of variable rate method, the rate of RM 0.22 per kWh is charged for the consumption less than or equal to 100 kWh. Any additional consumption is charged at RM 0.35 per kWh.arrow_forward1 public static int sum(int x, int y){ 2 int z = x +y; 3 return z; 4 } 5 public static void main(String[] args){ 6 … 7 sum(a+2, b); 8 … 9 } write the signature of the method sum: sum(int,int) *Method name/parameter list list local variables of sum: x, y, and y are local variables of the function. list the parameters of sum: int x, int y write the line number where a call to sum occurs 7 list the arguments for the above call list the return type of sum here ______________arrow_forwardPROBLEM STATEMENT: Return the factorial of the provided integer parameter. public class FactorialComputation{public static int solution(int n){// ↓↓↓↓ your code goes here ↓↓↓↓return 0;} Can you please help me with the question above the Language is Java and can yiu use the java code that i gave above to answer the questionarrow_forward

- The body mass index, BMI, is a measure used to determine if a person is overweight or not. We can calculate BMI from the weight of the person (in pounds) and the height (in inches) of the person.The formula for calculating BMI is:BMI = (weightInPounds * 703) divided by (heightInInches squared)In this problem, you will develop a Java program as a BMI calculator, that reads the user’s weight in pounds and height in inches, then calculates and displays the user’s body mass index BMI. Also, display the following information {from the US Department of Health} so the user can evaluate his/her BMI:BMI values:Underweight: less than 18.5Normal: between 18.5 and 24.9Overweight: between 25 and 29.9Obese: 30 or greaterarrow_forwardI keep coming up with the wrong answer, please help: Here is the code given: public class Billing {final static double TAX = 0.08;public static void main(String[] args) {final double HIGHPRICE = 24.99;final double MEDPRICE = 17.50;final double LOPRICE = 10.00;final int QUAN1 = 4;final int QUAN2 = 6;double bill;bill = computeBill(HIGHPRICE);System.out.println("The total for a photobook that costs $" +HIGHPRICE + " is $" + bill);bill = computeBill(MEDPRICE, QUAN1);System.out.println("The total for " + QUAN1 +" photobooks that cost $" +MEDPRICE + " is $" + bill);bill = computeBill(LOPRICE, QUAN2, 20.00);System.out.println("The total for " + QUAN2 +" photobooks that cost $" +LOPRICE + " with a $20 coupon is $" + bill);} public static double computeBill(double amt) {// Write your code here} public static double computeBill(double amt, int quantity) {// Write your code here}public static double computeBill(double amt, int quantity, double coupon) {// Write your code here}} Here is what they…arrow_forward**JAVA DEBUGGING** The files provided in the code editor to the right contain syntax and/or logic errors.
