- 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 pentagonal number is defined as n(3n-1)/2 forn = 1 , 2 , …, and so on. Therefore, the first few numbers are 1, 5, 12, 22,. . . . Write a method with the following header that returns a pentagonalnumber:public static int getPentagonalNumber(int n)For example, getPentagonalNumber(1) returns 1 and getPentagonalNumber(2) returns 5. Write a test program that uses this method to display thefirst 100 pentagonal numbers with 10 numbers on each line. Use the %7d formatto display each number.A pentagonal number is defined as n(3n−1) ∕ 2 for n = 1, 2, . . ., etc.. Therefore, the first few numbers are 1, 5, 12, 22, . . . . Write a method with the following header that returns a pentagonal number:public static int getPentagonalNumber(int n) For example, getPentagonalNumber(1) returns 1 and getPentagonalNumber(2) returns 5. In Java, Write a test program that uses this method to display the first 100 pentagonal numbers with 10 numbers on each line. Numbers are separated by exactly one space.
- Write a method with the following header to display an integer in reverse order: public static void reverse(int number) For example, reverse(3456) displays 6543. Write a test program that prompts the user to enter an integer then displays its reversal1). What will be returned from the following method? public static double methodXY() { double a = 6.5 + 8.5; if( a > 12) return a; else return 10; }The method half shown below, takes a variable of type int and returns the result of dividing the variable by 2. Write the overloaded method for half that accomplishes the same task for a variable of type double. public static int half(int val) { return val/2;}
- 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.Write a method with the following header to display threenumbers in decreasing order:public static void displaySortedNumbers(double num1, double num2, double num3)Write a test program that prompts the user to enter three numbers and invokes themethod to display them in decreasing order.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 simulates the Magic 8 Ball game. The class should have a method that returns an answer at random. Test your class by outputting the answer several times.Write a method orderFood() for the class Food that simulates ordering food. The method takes an integer as argument, which indicates the number of portions that are ordered. It then prints out a string showing the number of portions and the type of food ordered. The string needs to have the format as shown in the examples below. PythonAnalyze the following class, then choose the correct returnValueType for the method average. void int String double
