Exercise GradesStatistics (Method): Write a program called GradesStatistics, which reads in n grades (of int between 0 and 100, inclusive) and displays the average, minimum, maximum, median and standard deviation. Display the floating-point values upto 2 decimal places. Your output shall look like:Enter the number of students: 4Enter the grade for student 1: 50Enter the grade for student 2: 51Enter the grade for student 3: 56Enter the grade for student 4: 53{50,51,56,53}The average is: 52.50The median is: 52.00The minimum is: 50The maximum is: 56The standard deviation is: 2.29The formula for calculating standard deviation is:Hints:public class GradesStatistics {public static int[] grades; // Declare an int[], to be allocated later.// This array is accessible by all the methods.public static void main(String[] args) {readGrades(); // Read and save the inputs in int[] gradesprintArray(grades);System.out.println("The average is " + average(grades));System.out.println("The median is " +…

Note that 2 is the only even prime number. An odd integer is prime if it not divisible by any odd integer less than or equal to the square root of the number. Part2: A prime number whose reversal is also a prime number is called emirp. For example, 11, 13, 79 and 359 are emirps. Write a program that outputs to a ListBox the first 100 emirps. Your program must contain the method from Part 1 that returns true if a number is prime; false otherwise and another method that returns the reversal of a positive number. You can reverse the integer in the following way: • Convert the integer into a string value = num.ToString(); • Use the following code to reverse the integer string newNum = “”; for (int l = value.Length; l > 0; l--) newNum = newNum + value[l-1]; Also, your program should have a TextBox that will accept a positive integer from the…arrow_forwardJAVA Problem description:You are to write a program called Seasons that prompts the user for a month and day and displays the season in which that date occurs.

More specifically: Month – the month entered must be a valid month of the year (January – December). Day – the day entered must be a valid day for that month: January, March, May, July, August, October, December have 1-31 days. April, June, September, November have 1-30 days. February has 1-28 days (do not worry about leap years) Required program decomposition String getMonth(Scanner console) This method is called from the main method and should prompt for the month as a string…arrow_forward

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.

- 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 75arrow_forwardNOTE: JAVA language Write a program that asks the user for his first name and then prints it using a function/method called printName(). We do not expect the first name to exceed 20 letters. Then the program should print the name with a space between each character. Example: if the first name is Maryam, the :program will print Maryam -1 Maryam -2arrow_forwardInput a number value for LEFT, RIGHT and X. If LEFT is greater than RIGHT, display the first ten numbers in descending order starting from X. If RIGHT is greater than LEFT display the first ten numbers in ascending order starting from X. If RIGHT and LEFT are equal, display “Equal Value” Use the UML diagram below as a guide. The following methods are as follows. setValues(int,int,int) – accepts the value for X, LEFT and RIGHT as parameters and returns the following: 0 if LEFT and RIGHT are equal 1 if LEFT is greater than RIGHT 2 if RIGHT is greater than LEFT. displayCount(int) – accepts the integer that represents the status of RIGHT and LEFT, and then display the expected result.arrow_forward
