Question

Write and submit the source code for the following program. The program will use an integer array of size 10 to store the prices of smartphones. It will then determine and print the prices of the most expensive and cheapest phones. Use the following variables:

int[] prices = new int[10]; // Array of smartphone prices

Assignment

1. Ask the user for the price of each smartphone (using a for loop)
2. Sort the list of smartphones (once) from low to high price using the following statement:

Arrays.sort(prices);

3. Print the three most expensive phones in order of decreasing price using the sorted array and a for loop
4. Print the three cheapest phones in order of increasing price using the sorted array and another for loop

Sample Output

Enter all smartphone prices: 1100 1080 900 1200 900 700 550 800 400 250

Three Most Expensive Phones

1200

1100

1080

Three Cheapest Phones

250

400

550

Answer 1

import java.util.Arrays;
import java.util.Scanner;

public class SmartPhonePrices {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);

        System.out.print("Enter all smartphone prices: ");
        String s = scan.nextLine();

        String splits[] = s.split(" ");
        int arr[] = new int[splits.length];
        for(int i = 0;i<splits.length;i++){
            arr[i] = Integer.parseInt(splits[i]);
        }

        Arrays.sort(arr);

        System.out.println("Three Most Expensive Phones");
        for(int i = 1;i<=3;i++){
            System.out.println(arr[arr.length-i]);
        }

        System.out.println("Three Cheapest Phones");
        for(int i = 0;i<3;i++){
            System.out.println(arr[i]);
        }

    }
}
