Question

Write a program that reads three whole numbers and displays the average of the three number. Sample Run #: java Average3 Interactive Session.
1. Enter the first integer: 8
2. Enter the second integer: 10
3. Enter the third integer: 18
The average of 8, 10, and 18 = 12.0.

Answer 1

Answer:

The program to this question as follows:

Program:

import java.util.*; //import package

class Average //defining class Average

{

public static void main(String[] args) //defining main method

{

int a1,b2,c3;//defining integer variable

float avg; //defining float variable

Scanner obz=new Scanner(System.in); //creating scanner class object

System.out.print("input first number: "); //print message

a1=obz.nextInt(); //input value by user

System.out.print("input second number: "); //print message

b2=obz.nextInt(); //input value by user

System.out.print("input third number: "); //print message

c3=obz.nextInt(); //input value by user

avg=a1+b2+c3/3; //calculating average

System.out.print("The average of "+a1+","+b2+",and "+ c3+"="+ avg);//print value    

}

}

Output:

input first number: 8

input second number: 10

input third number: 18

The average of 8,10,and 18=24.0

Explanation:

In the above code, a class "Average" is defined inside this class the main function is declared in this method three integer variable "a1, b2, and a3" is declared, which input the value from the user side. in this method, a float variable avg is defined that calculates its average value.

• In the next step, a scanner class object is created, that uses the above integer variable values.  
• In the "avg" variable add all integer variables then divide its value by 3. At the print, method is used that prints avg variable value.
