Write a Java program to find the average of three numbers using the + and / arithmetic operator. First, it accepts three numbers of double type and then uses the arithmetic plus to add them and / operator to find the average.
package RemainingSimplePrograms; import java.util.Scanner; public class AvgOfThree1 { private static Scanner sc; public static void main(String[] args) { sc = new Scanner(System.in); System.out.print("Please Enter the first Number = "); double num1 = sc.nextDouble(); System.out.print("Please Enter the Second Number = "); double num2 = sc.nextDouble(); System.out.print("Please Enter the Third Number = "); double num3 = sc.nextDouble(); double average = (num1 + num2 + num3)/ 3; System.out.println("\nThe Average of Three Numbers = " + average); } }

In this example, we created a calAvg function that finds and returns three numbers’ average.
package RemainingSimplePrograms; import java.util.Scanner; public class AvgOfThree2 { private static Scanner sc; public static void main(String[] args) { sc = new Scanner(System.in); System.out.print("Please Enter the first = "); double num1 = sc.nextDouble(); System.out.print("Please Enter the Second = "); double num2 = sc.nextDouble(); System.out.print("Please Enter the Third = "); double num3 = sc.nextDouble(); double average = calAvg(num1, num2, num3); System.out.println("\nThe Average = " + average); } public static double calAvg(double a, double b, double c) { return (a + b + c)/3; } }
Please Enter the first = 99
Please Enter the Second = 124.7
Please Enter the Third = 33.89
The Average = 85.86333333333333
