Question

Max3.java: Write a program that reads 10 integers and displays top 3 records (i.e., the largest three elements). Please consider the extreme case when all integers are negative. For instance, by given -1, -2, …, -10, the display will be -1, -2, and -3.

Answer 1

import java.util.Scanner;

public class Max3 {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter 10 numbers: ");
        int[] arr = new int[10];
        for (int i = 0; i < 10; i++) {
            arr[i] = in.nextInt();
        }

        for (int i = 0; i < arr.length; ++i) {
            for (int j = 0; j < arr.length - 1; ++j) {
                if (arr[j] > arr[j + 1]) {
                    int temp = arr[j];
                    arr[j] = arr[j + 1];
                    arr[j + 1] = temp;
                }
            }
        }

        System.out.println("Three largest numbers entered are " + arr[9] + ", " + arr[8] + " and " + arr[7]);
    }
}
