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 37 41 46 50 55 Using java 64 69 73 78 82 87 91 96

- 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 Using java 32 33 34 35 36 37 38 39 40 43 46 49 501. Write a program that takes three numbers (a,b,c) from the user as input and finds the median of the three. The program has a method called median that takes 3 numbers as the parameter and returns the median. Use if-then-else statements to find the median. You can assume the three numbers are not the same. Sample Example: Enter 3 numbers 10 13 The median is 10 public class Median{ public static void main(String[] args){ Scanner input = new int a = int b = int c =Write a java program method that accepts a year as a parameter, the method then returns true or false if the entered year is a leap year or not. You may calculate the leap year as follows: 1. If the year is evenly divisible by 4, go to step 2. Otherwise go to step 5. 2. If the year is evenly divisible by 100, go to step 3. Otherwise go to step 4. 3. If the year is evenly divisible by 400, go to step 4. Otherwise go to step 5. 4. The year is a leap year (it has 366 days). 5. The year is not a leap year (it has 366 days).
- Question 2 Write a method int countMultiplesofFive (int x, int y) that returns the number of multiples of 5 bounded between x and y inclusive. In the main, ask the user to enter two positive numbers (both must be positive, if users enter a negative value, they keep reentering values until both numbers are positive). Use the method countMultiplesofFive to find and print how many multiples of 5 exists between the two entered numbers inclusive. Sample run 1: First random: 11 Second random: 80 There are 14 umber that are multiple of five between 11 and 80 Sample run 2: First random: 75 Second random: 33 There are 9 number that are multiple of five between 33 and 75Write a program that reads a student’s name together with his or her test scores.

The grade scale is asfollows:90-100, A; 80-89, B; 70-79, C; 60-69, D; 0-59, FYour program must use the following methods:(a) A value-returning method, calculateAverage, to determine and return the average of fivetest scores for each student. Use a loop to read and sum the five test scores. (This method doesnot output the average test score. That task must be done in the method main.)(b) A value-returning method, calculateGrade, to determine and return each student’sgrade. (This method does not output the grade. That task must be done in the method main.)Test your program on the following data. Read the data from a file and send the output to a file. Do notuse any global variables.

- QUESTION 2 A prime number is a number that is evenly divisible only by itself and 1. For example, the number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6. Write a method named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Demonstrate the method in a complete program. Tip: Recall that the % operator divides one number by another, and returns the remainder of the division. In an expression such as num1 % num2, the % operator will return 0 if num1 is evenly divisible by num2. QUESTION 3 Use the isPrime method that you wrote in previous question in a program that stores a list of all the prime numbers from 1 through 100 in a file. plz answer these question using javaWrite a method that returns a random number from alist of numbers passed in the argument. The method header is specified as follows:public static int getRandom(int... numbers)QUESTION 2 A prime number is a number that is evenly divisible only by itself and 1.
