- What is the output of the following two lines of Java code?System.out.println("2 + 2 = " + (2 + 2));System.out.println("2 + 2 = " + 2 + 2);arrow_forwardWrite the following mathematical expressions in Java.arrow_forwardwrite a program in java for converting binary numbers to decimal numbers, and conversely. [You can not use the conversion functions from the mathematical library.] Your program should do the following: 1. Ask the user if they want a Binary number converted to Decimal number, a Decimal number converted to a Binary number, or to quit the program. 2. Ask the user for the number, take the appropriate action and then print out the appropriate message.arrow_forward
- Write a complete Java program that does the following: 1. Ask the user to enter the last number and the second last number of his / her student ID. 2. Stores the entered numbers in adequate variables. 3. Finds and prints the following using "printf": The sum of the two numbers. The boolean value of comparing the equality of the two numbers using the equality operator. The value of the first number is raised to the power of the second number using a method from the class Math. Note: The class name of your Java program must be your first name. Your answer should have the code as text as well as the screenshot of the program output (using your own student ID) as a part of your answer. Otherwise, zero marks will be awarded.

- 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(); System.out.printf("After…arrow_forwardFor 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.
