a) Write a boolean method called sumDivisibleByFive that returns true if the sum of the digits of its integer
parameter is divisible by 5 and false otherwise. For example, if the parameter passed to the method is 73
then the sum of its digits is 10 (7+3) The method should return true since 10 is divisible by 5.
b) Write a main method that calls the method sumDivisibleByFive for the values between 10 and 100
inclusive 10 per line. This should output the following numbers:
14 19 23 28 32 3741 46 50 55
64 69 73 78 82 87 91 96

n Chapter 6, you continued to modify the GreenvilleRevenue program. Now, modify the program so that the major functions appear in the following individual methods:
GetContestantNumber - This method gets and returns a valid number of contestants and is called twice once for last year’s number of contestants and once for this year’s value
DisplayRelationship - This method accepts the number of contestants this year and last year and displays one of the three messages that describes the relationship between the two contestant values
GetContestantData - This method fills the array of competitors and their talent codes
GetLists - This method continuously prompts for talent codes and displays contestants with the corresponding talent until a sentinel value is entered
An example of the program is shown below:
Enter number of contestants last year >> 2 Enter number of contestants this year >> 3 Last year's competition had 2 contestants, and this year's has 3 contestants…
a) Write a boolean method called productDivisibleByThree that returns true if the product of the digits of
its integer parameter is divisible by 3 and false otherwise. For example, if the value passed to the method
is 23 then the product of its digits is 6 (2*3). The method should retum true since 6 is divisible by 3.
b) Write a main method that calls the method productDivisibleByThree for the values between 10 and 50
inclusive 10 per line. This should output the following numbers:
10 13 16 19 20 23 26 29 30 31

- 2) Two integers are said to be relatively prime if their greatest common divisor (GCD) is one. For example 12 and 13 are relatively prime, but 12 and 14 are not. a. Write a method called relativelyPrime that accepts two integer parameters A and B. The method should output if A, and B are relatively prime or nat. Use the following method header: public static void relativelyPrime(int A, int B) b. Write a test program (main) to test the method by asking the user to input two positive integers X and Y. Then the program will call the method relativelyPrime to output if X and Y are relatively prime or not.

You must use the abs(), pow(), and sqrt() methods of the Math class to perform the calculation. You may use a single assignment statement with a somewhat large expression, or you may break the expression into multiple assignment statements. The latter may be easier to debug if you are not getting the correct result. 5x +3} ( √8x* — 6x²³ + 4x² + |20x+1) (9x³+7x² +5x+3) Next, determine the number of digits to the left and to the right of the decimal point in the result. [Hint: You can convert the double variable into a String variable using the static method Double.toString(result). Then, on this String variable use the indexOf() method from the String class to find the position of the decimal point (".") and use the length() method to find the length. Knowing the location of the decimal point and the length of the String, you…arrow_forwardWhat is the difference between an argument and a parameter variable?arrow_forward

Suppose that your students take four courses - English, Mathematics, Science, and History. You should design a class that accepts all four course's numeric scores, calculates average and overall grade, and decides letter grade based on the overall grade. Your class should have a constructor, get and set methods of each course, a method that calculates the average of four courses, a method that calculates overall grade, and a method that decides letter grade. The overall grades are calculated as the following rate: Average of All four courses: 50% Quiz: 40% Attendance: 10% The letter grade is based on the following: 90.0 to 100.0 - A 80.0 to 89.9 - B 70.0 to 79.9 - C 65.0 to 69.9 - D less than 65 - F Your program demonstrates the class by asking the user to input four-course numeric scores, creating an object, and then reporting each course's score, average, overall…arrow_forward
