Question

Java Program

Please Read all directions carefully

Write a method named smallToLarge that asks the user to enter numbers, then prints the smallest and largest of all the numbers typed in by the user and the average (rounded to 2 decimal places). You may assume the user enters a valid integer number for the number of numbers to read. Here is an example dialogue:

/* initialize smallest and largest variables with the 1st user input for Number */

How many numbers do you want to enter? 3 
Number 1: 7
Number 2: 11
Number 3: -2

Smallest = -2
Largest = 11

Average = 5.33

Java code:

import java.util.Scanner;
public class Main
{
    //defining smallToLarge function
    static void smallToLarge(){
        Scanner input=new Scanner(System.in);
        //asking for count of numbers
        System.out.print("How many numbers do you want to enter? ");
        //initializing min,max,count and sum of numbers
        int max,min,count=0,sum=0;
        //accepting total number of numbers
        int no=input.nextInt();
        //checking if total number of numbers is 0 or less
        if(no<=0)
        //exiting
            return;
        //printing Number 1
        System.out.print("Number 1: ");
        //accepting it
        int num=input.nextInt();
        //setting it as max
        max=num;
        //setting it as min
        min=num;
        //incrementing count
        count++;
        //setting it as sum
        sum=num;
        //looping from 2 to number
        for(int i=2;i<=no;i++){
            //asking for Number
            System.out.print("Number "+i+": ");
            //accepting it
            num=input.nextInt();
            //adding it to sum
            sum+=num;
            //incrementing count
            count++;
            //checking if current number is max
            if(num>max)
            //setting max as num
                max=num;
            //checking if current number is min
            if(num<min)
            //setting min as num
                min=num;
        }
        //printing Smallest
        System.out.println("\nSmallest = "+min);
        //printing Largest
        System.out.println("Largest = "+max);
        //printing Average
        System.out.printf("\nAverage = %.2f",((float)(sum)/count));
    }
    public static void main(String[] args){
        //calling smallToLarge function
        smallToLarge();
    }
}
