- For this assignment, write a program called Payday.java that will compute and print a person's paycheck. The program will ask the user for the number of hours they worked and their hourly payrate. It will ask the person if they are a union member, in which case 5% of the salary will be withheld for union dues. It will ask the person if the percentage they wish to set aside for their medical savings account. It will then apply a sliding tax scale, defined as follows: Greater than or equal to $2,500 $1,500 up to $2,500 $500 up to $1,500 Less than $500 25% 15% 10% 5% The program must then print a formatted paycheck that shows their gross pay, union deduction, medical deduction, taxes withheld, and net pay. Use a function to determine the tax rate. Use a different function to print the nicely formatted paycheck. Your program should operate like this: ********** ********** Payday V1.0 ***: ******** Enter name: Ray Klump Enter hours worked: 43.25 Enter hourly pay rate: 17.50 Are you a union…Prime number is the number that is divided by one and itself only, Twin Prime is a pair of prime numbers that differ by 2. For example, 3 and 5 are twin primes, 5 and 7 are twin primes, and 11 and 13 are twin primes. Write a java program to find all twin primes within a range of 1 up to a number entered by user, such that, that the entered number should be greater than 10. The program has to have a method that takes an integer as a formal parameter and returns if that number is prime or not. Display the output as follows: Enter an integer (greater than 10): 7 Not accepted number! Enter an integer (greater than 10): 50 The number of twin prime numbers up to 50 are: (3, 5) (5, 7) (11, 13) (17, 19) (29, 31) (41, 43)Write a program in java Write a program that asks the user to enter five test scores. The program should displaya letter grade for each score and the average test score. Write the following methods inthe program:• calcAverage—This method should accept five test scores as arguments and return theaverage of the scores.• determineGrade—This method should accept a test score as an argument and return aletter grade for the score, based on the following grading scale:(attached photo)
- Design a program that applies encapsulation in java Write a program with which you can convert a human height given in feet and inches to centimeters. The program should ask the user to type in his or her height in two parts: first the height in feet and then the inches part for the height. (A person can say that his or her height is, for example, 5 feet and 9 inches. That would be 30.48 * 5 + 2.54 * 9 centimeters. There can be thus two separate input statements in the program. After the program has received the feet and the inches, it should calculate the corresponding value in centimeters and print it to the screen. You can input the values to int variables but the calculation results could be stored in variables of type double.In this exercise, you have to implement a calculator which can perform addition, subtraction, multiplication, and division. Problem Statement# Write a Java class called Calculator with ● private fields: ○ num1 and num2 (double type) And methods: ● add(), a method which returns the addition of two numbers ● subtract(), a method which returns the subtraction of num1 from num2 ● multiply(), a method which returns the multiplication of numbers ● divide(), a method which returns the division of num2 by num1 ● Define a parameterized constructor which takes two parameters num1 and num2 and assigns these variables to the respective fields in the class. Input# Pass double point numbers in the parameterized constructor Output# addition, subtraction, division, and multiplication Sample Input# Calculator obj = new Calculator(10, 94); obj.add() obj.subtract() obj.multiply() obj.divide() Sample Output# 104 84 940 9.4 Part of the Solution class Calculator { // write class fields here public…not handwritten Explain Meadowdale Dairy Farm sells organic brown eggs to local customers. They charge $3.25 for a dozen eggs, or 45 cents for individual eggs that are not part of a dozen. Write a class that prompts a user for the number of eggs in the order and then display the amount owed with a full explanation. For example, typical output might be, "You ordered 27 eggs." "That's 2 dozen at $3.25 per dozen and 3 loose eggs at 45.0 cents each for a total of $7.85."
- 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.in Java Tasks Write a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is 2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Don't display the computer's choice yet.) 2. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. (You can use a menu if you prefer.) 3. The computer's choice is displayed. Tasks 4. A winner is selected according to the following rules: a. If one player chooses rock and the other player chooses scissors, then rock wins. (The rock smashes the scissors.) b. If one player chooses scissors and the other player chooses paper, then scissors wins. (Scissors cuts paper.) C. If one player chooses paper and the other player chooses rock, then paper wins. (Paper wraps…Part 2 - OddOrEven ClassIn bluej. Write a program that prompts the user to enter an integer. The program should display “The input is odd" to the screen if the input is odd and displays “The input is even" to the screen if the input is even. Hint: Consider using the mod (%) operator.
- JAVACreate a class called Quadratic for representing a one-variable quadratic expression of the form: ax2 + bx + c a,b and c here are the coefficients. The class should contain the following methods: * A constructor that accepts values for a, b, and c. * public double getA() * public double getB() * public double getC() * public double evaluate (int x) * will return the value of the expression at point x * public double discriminant() - that will return (b2 - 4ac) * public boolean isImaginaryRoots() - roots are imaginary if (b2 - 4ac) < 0 * public boolean isRealRoots() - roots are real if (b2 - 4ac) >= 0 // these methods can only be invoked if the roots are not imaginary * public float firstRoot() * public float secondRoot() * public boolean isPerfectSquare(); // If the first and second roots are equal * Try to override the toString methods * Write a sample main program that will work as shown below. Example output: coefficient a: 4 coefficient b: 4 coefficient c: 1…In this exercise you will write a program to compute the distance between any two geo locations. In this program you will ask the user for four numbers. starting latitude starting longitude ending latitude ending longitude Then, using the GeoLocation class and our earlier example as a reference, compute the distance in miles between the two locations. A sample program run should match exactly as below: Enter the latitude of the starting location: 48.8567 Enter the longitude of the starting location: 2.3508 Enter the latitude of the ending location: 51.5072 Enter the longitude of the ending location: 0.1275 The distance is 208.08639358288565 miles. setInputs(String[]) should be included /* * This class stores information about a location on Earth.
