- Using Java, Write a method named isEven that accepts an int argument. The method should return true if the argument is even, or false otherwise. Also write a program to test your method.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 96Write 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.
- Create a method that takes a value and tell whether it is null or not.Declared as: boolean isZero (float a)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 50T/F(If false, correct the statement to make it true) - A void method will return an int value
- Make sure each program has at least one method in addition to its driver method(main). Or use one driver main method and write method(s) for each of the program. Write a java program that calculate and display the GPA for a student that takes only four (4) classes. The program shall require the user to input their credit hour(s) and Letter grade for each of the classes. You may use an accumulator variable and loops. Weights based off of letter grades: A = 4, B = 3, C = 2, D=1, F = 0 GPA = Accumulator variable of (grade weight*credit hours) /total credit hoursuse only C# programming Write a method call CubeIt(int x, ref int cube) that takes two arguments and does not return a value. The method will cube the first argument and assign it to the second argument.In your main, call this method twice and print the value of the parameters after each method call. Write a method with the following header: static void CalculateTuitionFee(int numberOfCourses, double costPerCourse, ref double fees). This method will calculate and assign the required fees amount to the third argument. [Fees = number of courses * cost per course + 15.25].From your program Main() method, call the CalculateTuitionFee () method four times supplying different arguments each time and display the value of the third argument after each method call. Write a method that takes four parameter of type int. The method will assign the sum of the first two arguments to the third and the difference of the first two to the fourth. This method should be coded so that the calling…True or False? Arrays cannot be passed as parameters, but must be used only in the main method.
- 3) The following method should return true if the int parameter is even and either positive or 0, and false otherwise.Which set of code should you use to replace … so that the method works appropriately?public boolean question3(int x) { … }a) if (x = = 0) return true; else if (x < 0) return false; else return question3(x – 1);b) if (x = = 0) return false; else if (x < 0) return true; else return question3(x – 1);c) if (x = = 0) return true; else if (x < 0) return false; else return question3(x – 2);d) if (x = = 0) return false; else if (x < 0) return true; else return question3(x – 2);e) return(x = = 0);Write a method that prints numbers using the following header:public static void printNumbers(int num1, int num2, intnumberPerLine)This method prints the characters between num1 and num2 with the specifiednumbers per line. Write a test program that prints ten characters per line from 1to 100. Numbers are separated by exactly one space.Class: DoubleMethod Write a method using the header below public static double readDouble(String prompt) that displays the prompt string, followed by a space, then reads a floating-point number from the user, and returns it. Here is a typical usage: salary = readDouble("Please enter your salary:");percentageRaise = readDouble("What percentage raise would you like?");Write a test program to test the method.
