Parking Charges Program in java Write a program that works out the amount a person has to pay for parking in a car park in a tourist town. If they say they are disabled, they are told it is free. Otherwise they enter the number of hours as a whole number (1-8) that they wish to park as well as whether they have an “I live locally” badge or are an old age pensioner both of which leads to a discount. The program tells them the cost to park. The calculation is done in this program as follows. If they are disabled it is free. Otherwise ... Take number of hours they wish to park and give a basic charge: • • • • 1 hour: 3.00 pounds 2-4 hours: 4.00 pounds 5-6 hours: 4.50 pounds 7-8 hours: 5.50 pounds Next modify the resulting charge based on whether they are local or not: • If local: subtract 1 pound If OAP: subtract 2 poundsYour program MUST include methods including ones that - asks for the hours and returns the basic charge. - asks whether they live locally /…
Interest on a credit card’s unpaid balance is calculated using the average daily balance. Suppose that netBalanceis the balance shown in the bill, paymentis the payment made, d1is the number of days in the billing cycle, and d2is the number of days payment is made before the billing cycle. Then the average daily balance is: averageDailyBalance = (netBalance * d1 –payment * d2) / d1 if the interest rate per month is say, 0.0152, then the interest on the unpaid balanceis: interest = averageDailyBalance * 0.0152 Design a program that accepts as input netBalance, payment, d1, d2, and interest rate per month. The program outputs the interest charged. Format your output to two decimal places. C++

Language: JAVA Leap-Year Write a program to find if a year is a leap year or not. We generally assume that if a year number is divisible by 4 it is a leap year. But it is not the only case. A year is a leap year if − It is evenly divisible by 100 If it is divisible by 100, then it should also be divisible by 400 Except this, all other years evenly divisible by 4 are leap years. So the leap year algorithm is, given the year number Y, Check if Y is divisible by 4 but not 100, DISPLAY "leap year" Check if Y is divisible by 400, DISPLAY "leap year" Otherwise, DISPLAY "not leap year" For this program you have to take the input, that is the year number from an input file input.txt that is provided to you. The input file contains multiple input year numbers. Use a while loop to input the year numbers from the input file one at a time and check if that year is a leap year or not. Create a class named LeapYear which will contain the main method and write all your code in the main…
Q3: Superheroes Supervillains are tired of Toronto condo rental prices, so they are leaving Toronto for Mississauga. Luckily, we have valiant superheroes that can deal with them. The superhero () has a name , an intelligence score , and a strength score .ni-th0 = gin[x] + s[x] Detective Zingaro has asked for your help. For each of the supervillains, tell him the name of the superhero that should deal with that supervillain. Note: A superhero can be assigned to multiple supervillains (or none at all). Note: whenever there are multiple superheroes that satisfy the given requirements for a supervillain, report the one whose name is lexicographically smallest (i.e. the one that’s the smallest according to Python’s ordering of strings). It’s guaranteed that superheroes have distinct names. Hint: Tuples of multiple elements may be helpful here. In python, you can compare two tuples and . If and are different, the result is the same as comparing and . If and are equal, the result is the same…
