I'm pretty new to coding. Here I need to write a method to find the second smallest integer in a given array. What I have managed to put together is a method to find the smallest integer. I'm thinking I need another for loop to test my 'low' variable to all the integers in the array again, thus finding the next lowest integer. I can put it into words as to what I want, but I have trouble actually coding it. Any words of advice, suggestions or corrections would be awesome. Also, I'd like to figure it myself, so no doing it for me! take a look... Code: public static void main(String[] args) { int array[] = {7, 9, 6, 8, 13}; int low = 9999999; for (int counter = 0; counter < array.length; counter++) { if (low > array[counter]) { low = array[counter]; counter++; } } System.out.println(array[low]); }

But I posted my results. I threw in another for loop, but also used if-else statements to store minimum and second lowest values. Looks pretty good, and runs fine. Any suggestions as what I could improve would be great. Thanks. Code: import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner k = new Scanner(System.in); int array[] = new int[5]; System.out.println("Enter your 5 digits, separated by spaces:"); for (int i = 0; i < 5; i++) { array[i] = k.nextInt(); if(array.length != 5) { System.out.println("Error"); System.out.println("Please try again."); } } int min = 0; int second = 0; if (array[0] < array[1]) { min = array[0]; second = array[1]; } else { min = array[1]; second = array[0]; } for (int counter = 2; counter < 5; counter++) { if (array[counter] <= min) { second = min; min = array[counter]; } else { if (array[counter] < second) { second = array[counter]; } } } System.out.println("The second smallest number is " + second); } }
