- Java Programming Assignment: Sammer, a smart child, just learned about series and numbers. He wrote the numbers in sequence and went to have milk. Unfortunately, while going to the shop he had a small accident and the coins are mixed with the other lady coin (May also mixed negative numbers) Now that you have been given these mixed numbers, your task is to help the little one finds the first missing natural number by using the Java programming language. Sample Input: 1 265-88 6 7 Sample Output: 1In java Write a program that computes the average of 5 students grades which are entered by the user.n this lab, you complete a prewritten Python 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 make 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.
- Control structures: In Java only please. Output the position of the largest number and the largest number in the squence a0, a1, a2....ak.

Test your program for the following values of x: 75, 111, 678, 732, 873, 2048, and 65535. Thank youIn java Write a program in java to print if a user can marry or not. Assume the marrying age is 21Please 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. (1) Design a class named Complex for representing complex…
- 2. Write a Java program to calculate and print the monthly paycheck for an employee. The net pay is calculated after taking the following deductions: Federal income tax State income tax 15% 5% %3D Social security tax Medicare/Medicaid Pension plan 5% %3D 3응 %3D 8웅 %3D Health insurance $125.00 %3D Your program should ask the user to input the employee ID, last name, first name, and the earnings (gross amount) for current month. The output should be the net pay, after deductions. Format the output to have 2 decimal places. Sample output: Employee ID: Employee Name: 12345 John Doe EARNINGS 4500.00 Federal Tax 675.00 State Tax 225.00 Social Security 225.00 Medicare/Medicaid 135.00 Pension Plan 360.00 Health Insurance 125.00 ===== ===== = === NET PAY 2755.00In 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…Use Java ⮚ Roman numerals are represented by seven different symbols: I, V, X, L, C, D and M. ⮚ Symbol Value I 1 V 5 X 10 L 50 C 100 D 500 M 1000.⮚ For example, 2 is written as II in Roman numeral, just two ones added together. 12 is written as XII, which is simply X + II. The number 27 is written as XXVII, which is XX + V + II. ⮚ Roman numerals are usually written largest to smallest from left to right. However, the numeral for four is not IIII. Instead, the number four is written as IV. Because the one is before the five we subtract it making four. The same principle applies to the number nine, which is written as IX. There are six instances where subtraction is used: I can be placed before V (5) and X (10) to make 4 and 9. X can be placed before L (50) and C (100) to make 40 and 90. C can be placed before D (500) and M (1000) to make 400 and 900. ⮚ Given a roman numeral, convert it to an integer
- JAVA Programming Language: According to the American Heart Association, as you exercise you should periodically check your heart rate to ensure you are in your target zone. Your target zone is a range that is 50% to 85% of your maximum heart rate. The formula for calculating a persons maximum heart rate is 220 minus your age in years. Write a program that reads the users current heart rate, birthday, and the current day (each consisting of month, day, and year). The program should calculate the persons age (in years), the person's maximum heart rate, and the person's target heart rate zone range. Output the users age, current heart rate, target zone range. If their heart rate is in the target zone congratulate them, if it is out of their target zone warn them. Required Methods (Write these first and use them in your algorithm): (your code, particularly for computeAge, must be 100% clear and documented - it's the core of this assignment!) int computeAge(int birthMonth, int birthDay,…Write a program in Java Object Oriented language that performs Addition, Subtraction, Multiplication and Division of two fractions.Make a program in Java Object Oriented language that performs Addition, Subtraction, Multiplication of two complex numbers (a+bi)Write a program in Object Oriented Java language that adds and subtracts two polynomials of the form ax2+bx+c In this case the menu will ask if you want to use fractions, complexes or polynomials and when you select the option, it will show all the requested operations.
