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

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

- (Intro to Java) explain the answers to the below questions using step-by-step explanation.arrow_forwardHere's the problem " (Math: approximate the square root) There are several techniques for implementingthe sqrt method in the Math class. One such technique is known as theBabylonian method. It approximates the square root of a number, n, by repeatedlyperforming a calculation using the following formula: nextGuess = (lastGuess + n / lastGuess) / 2 When nextGuess and lastGuess are almost identical, nextGuess is theapproximated square root. The initial guess can be any positive value (e.g., 1).This value will be the starting value for lastGuess. If the difference betweennextGuess and lastGuess is less than a very small number, such as 0.0001,you can claim that nextGuess is the approximated square root of n. If not, next-Guess becomes lastGuess and the approximation process continues.

For example, the number 5 is prime because it can be evenly divided by only 1 and 5. The number 6, however, is not prime because it can be evenly divided by 1, 2, 3, and 6. Write a Boolean method named IsPrime that takes an integer as an argument and returns true if the argument is a prime number or false otherwise. Use the method in an application that lets the user enter a number and then displays a message indicating whether the number is prime.arrow_forwardUrgent Answer Have a nice day:)arrow_forward

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. Sample Run 1: Enter Two positive integers X and Y: 12 13 12 and 13 are relatively prime Sample Run 2: Enter Two positive integers X and Y: 12 14 12 and 14 are not relatively primearrow_forward
