- 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: 1Java programming pls 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 the example below.

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,…

- Java Program Mall Parking System Westfield Shopping Mall is having a common two-wheeler parking stand in its basement. This parking facility is utilized by many of their customers regularly and they charge it for 10 Rupees per hour as parking fee. To make this facility more comfortable, they wish to automate the parking fee calculation based on the In-time and Out-time of a vehicle. For each vehicle entry, they will give a token which has the current date and time printed as In-time. The Out-time of each vehicle will the greater than the In-time. Help them to calculate the total Parking Fee by getting the In-time and Out-time as inputs. Note: The input In-time, must be in dd/MM/yyyy HH:mm format and must be lesser than the current system time for at-least 1 Minute. Otherwise, print “<In-Time> is an Invalid In-Time” and terminate. The input Out-time, must be in dd/MM/yyyy HH:mm format and must be greater than the In-time for at-least 1 Minute. Otherwise, print…JAVA Programming Problem 2 - Diving In the sport of diving, seven judges award a score between 0 and 10, where each score may be a floating-point value. The highest and lowest scores are thrown out and the remaining scores are added together. The sum is then multiplied by the degree of difficulty for that dive. The degree of difficulty ranges from 1.2 to 3.8 points. The total is then multiplied by 0.6 to determine the diver’s score. Write a computer program that will ultimately determine the diver’s score. This program must include the following methods: A method name inputValidScore that inputs one valid score for one judge for one diver. This method will return the valid score. A method named inputAllScores that creates an array to store the scores for all judges for the diver. This method will fill the array with a valid score from each judge. This method does not take input arguments, but it does return the array of scores. A method named inputValidDegreeOfDifficulty that inputs a…Java program to convert Fahrenheit to Celsius: This code does temperature conversion from Fahrenheit scale to Celsius scale.
