- A primitive variable is passed from one method to another method by in Java. pass by value O pass by referenceIn 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…JAVA PROGRAM Can You Please describe the method overloading on the subtraction of two numbers.

- JAVA Notes: all program codes should be written with method/s separated from the main() structure. Use a separate code files for each. Programming Problems: 1. Write a value-returning method, isVowel, that returns the value true if a given character is a vowel, otherwise return false. Also write a program to test your method. 2. Write a program that prompts the user to enter a sequence of characters and output the number of vowels and consonants separately. (use the method isVowel written in problem 1). 3. Write a program that output inflation rates for two successive years and whether the inflation rates are increasing or decreasing. Ask the user to input the current price of an item and its price, one year and two years ago. To calculate the inflation rate for a year, subtract the price of the item for that year and from the price of the item from one year ago and then divide the result by the price a year ago. Your program must contain a method to calculate the results. Use…NOTE: JAVA language Write a program that asks the user for his first name and then prints it using a function/method called printName(). We do not expect the first name to exceed 20 letters.
