- Please use java A complex number is a number in the form a+bi, where a and b are real numbers and i is √(-1) The numbers a and b are known as the real part and imaginary part of the complex number, respectively. You can perform addition, subtraction, multiplication, and division for complex numbers using the following formulas: a + bi + c + di = (a+c) + (b+d)i (addition) a + bi − (c + di) = (a−c) + (b−d)i (subtraction) (a + bi) * (c + di) = (ac−bd) + (bc+ad)i (multiplication) (a + bi) / (c + di) = (ac+bd) / (c2+d2) + (bc−ad)i / (c2+d2) (division) You can obtain the Absolute Value for a complex number using the following formula: |a + bi| = √(a2 + b2) A Complex number can be interpreted as a point on a plane by identifying the (a,b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in example below.

Example of a Newton number is 1634 since: 1634 1*1*1*1+6*6*6*6+3*3*3*3+4*4*4*4 which is: 1+ 1296+256+81. Write a Java program that checks whether or not a number is a Newton number. Sample Run1: Enter an integer number of 4 digits: 3712 3712 is not a Newton number Sample Run2: Enter an integer number of 4 digits: 1634 1634 is not a Newton number Sample Run2: Enter an integer number of 4 digits: 234 Invalid input!!arrow_forwardUnderstanding ifStatements Summary In this lab, you complete a prewritten Java program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts: The charge for all signs is a minimum of $35.00. The first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. If the sign is made of oak, add $20.00. No charge is added for pine. Black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering. Instructions 1. Ensure the file named HouseSign.java is open. 2. You need to declare variables for the following, and initialize them where specified: A variable for the cost of the sign initialized to 0.00 (charge). A variable for the number of characters initialized to 8 (numChars). A variable for the color of the characters initialized to "gold" (color). A variable for the…arrow_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_forwardIn java please Compute the minimum or maximum of two integers without using if else Hint : you can use ternary operatorsarrow_forwardWrite a complete Java program that performs the following tasks: Ask the user to enter the last two digits of his/her student ID. Break the number into two digits using arithmetic operators, then store the first and second digits in integer variables named digit1 and digit2 Find and print the following: The product of digit1 and digit2. The sum of digit1 and digit2 The average of digit1 and digit2 The maximum of the two numbers; digit1 digit2 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.arrow_forward
- Calculate your Physics final Write a Java program to solve the following problem: grade based on the following: Assessment Percent Lab Activity(ies) Quiz (zes)/Test (s) 10% 10 Assignment (s) 208 Midterm Exam (8) 20% Final Exam 40% Theory grade is the quiz/test, midterm and final exam marks. Practical grade is the assignment and lab marks. Final grade is all five marks. But the calculation of Final grade needs to comply with the following rule: If either of the practical or theory grade is less than 50%, the final grade is the lesser of the two. A grade letter must be assigned based on the final grade (See the courses outline for the distribution of grades) You must implement input validation for each mark as follows: Lab mark must be out of 10. Quiz/Test mark must be out of 10. Assignment mark must be out of 20. Midterm mark must be out of 20. Final Exam must be out of 40.

- 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_forwardWrite an application in Java that asks the user to enter two integers, obtains them from the user and prints their sum, product, difference and quotient (division). Sample Run Enter first integer: 18 Enter second integer: 5 Sum is 23 Product is 90 Difference is 13 Quotient is 3 Note: The exact division of 18 by 5 is 3.6. However, assuming you are using only integer (int) variables in your program, then the integer division of 18 by 5 is 3. IMPORTANT. Follow the various style conventions we've discussed in class (variable naming, constants, spaces, etc) including putting comments in your program.arrow_forwardIn java Write a program that does the following:- reads an unspecified number of integers- determines how many positive and negative values have been read- computes the total and average of the input values (not counting zeros).
