Intro to Java 10/17/20 Homework

For your homework today, write a program that calculates and prints out the average of three numbers. It should declare and initialize four double variables, one for each number and one for the average. Challenge: use a Scanner to read in the three numbers from the user. (You do not have to use any functions to solve this homework assignment.)

import java.util.Scanner; class Main { public static void main(String[] args) { System.out.println("type three numbers for their average"); Scanner x = new Scanner(System.in); Scanner y = new Scanner(System.in); Scanner z = new Scanner(System.in); double a = x.nextDouble(); double b = y.nextDouble(); double c = z.nextDouble(); double d = ((a+b+c)/3); System.out.println(d); } }

class Main { public static void main(String[] args) { double a = 4; double b = 8; double c = 12; double average = (a + b + c) / 9; System.out.println(average); } }
