a) Write a method that calculates the result of the following formula: x2 + (x + k)² + (x + 2k)? + (x + 3k)2+. + (x + nk)? The header of the method is as follows public static double sum(double x, double k, int n) b) Write a main method in which you ask the user to enter the value of x, and then call the sum method to print the result of the above sum with k = 2.5 and n= 10. Sample run 1: Enter the value of x: 4.5 The result of the sum is: 3866.5 Sample run 2: Enter the value of x: -1.2 The result of the sum is: 2092.09

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 50
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

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. 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 prime
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 75
Write a method that returns the lcm (least common multiple) of an unspecified number of integers. The method header is specified as follows: public static int lcm(int... numbers) Write a test program that prompts the user to enter five numbers, invokes the method to find the lcm of these numbers, and displays the lcm.

Write a program that contains 2 methods, main and printLine (10 points) 1) The printLine method will do the following: a. receives 3 parameters: the first character, the second character and the number of times to print the characters. b. using a loop, the program prints a line of text consisting of the first character concatenated with the second character repeated the number of times entered by the user. 2) The main method will do the following: a. asks the user for a character. b. using a Scanner gets the character C. asks the user for a second character. d. using a Scanner gets the second character e. asks the user how many times to print f. using a Scanner gets the number of times to print g. calls the method printLine. Sample Run: Enter a character ? Enter a second character Enter the number of times to repeat 5 ?*?*?*?"?* Enter a character ! Enter a second character @ Enter the number of times to repeat 8 !@!@!@!@!@!@!@!@ Submission • Copy and paste your code • Screen shot the…

basic java please Write a void method named emptyBox()that accepts two parameters: the first parameter should be the height of a box to be drawn, and the second parameter will be the width. The method should then draw an empty box of the correct size. For example, the call emptyBox(8, 5) should produce the following output: ***** * * * * * * * * * * * * ***** The width of the box is 5. The middle lines have 3 spaces in the middle. The height of the box is 8. The middle columns have 6 spaces
