(Displaying a Square of Asterisks) Write a method squareOfAsterisks that displays a solid square (the same number of rows and columns) of asterisks whose side is specified in integer parameter side. For example, if side is 4, the method should display
* * * *
* * * *
* * * *
* * * *
Incorporate this method into an application that reads an integer value for side from the user and outputs the asterisks with the squareOfAsterisks method.

- Java Programming One day, Fred and his N friends were playing a card game in which each player throws a card with a number written on it. The cards are such that a number X is written on front of the card, and the negative of that number is written on the back side of the card. This game has the following rules: - Each of the N players is asked to throw a card. After all the N cards are thrown, Fred has to flip one or more cards in consecutive order, only orice. Your task is to help Fred flip the cards in such a way that the sum of the numbers, on front face of the cards, is the maximum. Your Task is to return the maximum sum of the numbers, on the front cards.

Output the grades entered, the lowest and highest grade, the average grade, how many grades are above the average and how many are below and the letter grade for the average grade. Create a method that returns the lowest grade. Create a method that returns the highest grade. Create a method that returns the average grade. Create a method that returns how many grades were above the average. Create a method that returns how many grades were below the average. Create a method that returns the letter grade of the average (90-100 – A, 80-89 – B, 70-79 – C, < 70 – F)arrow_forwardExercise 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.

- use java as programming languagearrow_forwardQ1) Write a method that checks whether two words are anagrams. Two words are anagrams if they contain the same letters in any order. For example, "silent" and "listen" are anagrams. Write a test program that prompts the user to enter two strings and, if they are anagrams, displays "anagram", otherwise displays "not anagram". Note: The header of the method is as follows: public static boolean isAnagram(String s1, String s2) Sample Input #1: Enter two strings: Silent listen Sample Output #1: The string “Silent” and “listen” are anagrams. Sample Input #1: Enter two strings: teach peach Sample Output #1: The string “teach” and “peach” aren’t anagrams.arrow_forwardbasic 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 spacesarrow_forward

For reference, we will use the following date cutoffs for the various seasons: Winter December 21 – March 19 Spring March 20th – June 20th Summer June 21st – September 20th Fall September 21st – December 20th Data Validation For this program, you'll write a specific method to perform data validation based on the month and day entered. 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
