Question

*This needs comments for each line of code. Thanks in advance!*

import java.util.Scanner;
public class LabProgram {
    public static void main(String[] args) {
        Scanner scnr = new Scanner(System.in);
        int numCount = scnr.nextInt();
        int[] Array = new int[numCount];
      
        for(int i = 0; i < numCount; ++i) {
            Array[i] = scnr.nextInt();
        }

        int jasc = Array[0], gws = Array[1], numbers, tempo;

        if (jasc > gws) {
            tempo = jasc;
            jasc = gws;
            gws = tempo;
        }
        for (int i = 2; i < numCount; ++i) {
            numbers = Array[i];
            if (numbers < jasc) {
                gws = jasc;
                jasc = numbers;
            } else if(numbers < gws) {
                gws = numbers;
            }
        }
        System.out.println(jasc + " " + gws);
    }
}

Answer 1

thanks for the question, here are the comments. The program find the smallest two numbers provided by the user.

I have commented each line so that you can follow whats going on and understand.

Hope this helps, and let me know for any help with any other questions. thanks

import java.util.Scanner;

public class LabProgram {
    public static void main(String[] args) {
        // create an object of Scanner to read user input
        Scanner scnr = new Scanner(System.in);
        int numCount = scnr.nextInt(); // get the size of the array
        int[] Array = new int[numCount]; // create an empty int array of size = numCount

        // get the numbers for each element in the array
        for (int i = 0; i < numCount; ++i) {
            Array[i] = scnr.nextInt();
        }
        // assign the first two numbers two jasc and gws
        // create temporary variables for swapping the numbers
        int jasc = Array[0], gws = Array[1], numbers, tempo;
        // if the first number is greater than the second lowest number
        // swap the numbers
        if (jasc > gws) {
            tempo = jasc;
            jasc = gws;
            gws = tempo;
        }
        // iterate over each element in the array starting at index 2
        for (int i = 2; i < numCount; ++i) {
            numbers = Array[i]; // get the current number
            // if current number is smaller than the smallest number
            // swap the numbers
            if (numbers < jasc) {
                gws = jasc; // assign the 2nd smallest number to the current smallest number
                jasc = numbers; // assign the current smallest number to the current number
            } else if (numbers < gws) {
                // if the current number is smaller than the 2nd smallest number assign the 2nd smallest number to the current number
                gws = numbers;
            }
        }
        // print the smallest ans 2nd smallest number to the console
        System.out.println(jasc + " " + gws);
    }
