I need to create a code for this prompt: In this project we will build a generic UserInput class for getting keyboard input from the user. Implementation: The class UserInput is a 'Methods only' class, and all the methods should be declared static. Look at the TestScanner.java program at the bottom of this page that inputs a string, int and double. It shows you how to use Scanner class to get input from the keyboard. Write FOUR simple methods, one...
please help me with this problem The following program uses if-else-if statements to determine a letter grade. Rewrite it using if statements with logical operators (&&, ||, !) to produce the same output when given the same inputs. import java.util.Scanner; public class GradeCalculator{ public static void main(String[] args){ int grade; Scanner input = new Scanner(System.in); System.out.println("Enter numeric grade out of 100: "); grade = input.nextInt(); if (grade >= 90){ System.out.println("Congratulations!

Java programming question: Here is the feedback I received "sort fails. Use Arrays class method to sort." The actual question: Write a program as follows: Declare a five element array of Strings. Use a for loop and keyboard input to populate the array with the names of five friends. Sort the array in alphabetical order. Use a foreach loop to print the sorted array of friends, all on one line. Sample Output (inputs in italics) Enter the names of five...
