Answer:
Please find below program
Explanation:
import java.util.Scanner;
public class Tester {
public static void main(String[] args) {
// create an object of scanner class
Scanner scanner = new Scanner(System.in);
//prompt user to enter first number
System.out.println("Enter first integer: ");
// read value from entered by user and keep it in num1
int num1 = scanner.nextInt();
//prompt user to enter second number
System.out.println("Enter second integer: ");
// read value from entered by user and keep it in num2
int num2 = scanner.nextInt();
//prompt user to enter third number
System.out.println("Enter third integer: ");
// read value from entered by user and keep it in num3
int num3 = scanner.nextInt();
//close scanner as we have done with user input
scanner.close();
//calculate sum
int sum = num1+num2+num3;
//calculate average
int average = sum/3;
//calculate product
int product = num1*num2*num3;
//find out largest number
int largest = 0;
if (num1>=num2){
if(num1>=num3)
largest = num1;
else
largest = num3;
}else {
if(num2>=num3)
largest = num2;
else
largest = num3;
}
// find out smallest number
int smallest = 0;
if (num1<=num2){
if(num1<=num3)
smallest = num1;
else
smallest = num3;
}else {
if(num2<=num3)
smallest = num2;
else
smallest = num3;
}
// print all the information
System.out.println("Sum of three numbers : "+sum);
System.out.println("Product of three numbers : "+product);
System.out.println("Average of three numbers : "+average);
System.out.println("Smallest number : "+smallest);
System.out.println("Largest number : "+largest);
}
}
