  1. POTaking User Input for an Array
    text
    copied!<p>A link to the assignment: <a href="http://i.imgur.com/fc86hG9.png" rel="nofollow">http://i.imgur.com/fc86hG9.png</a></p> <p>I'm having a bit of trouble discerning how to take a series of numbers and apply them to an array without a loop. Not only that, but I'm having a bit of trouble comparing them. What I have written so far is:</p> <pre><code>import java.util.Scanner; public class Lottery { public static void main(String[] args) { int userInputs[] = new int[5]; int lotteryNumbers [] = new int[5]; int matchedNumbers =0; char repeatLottery = '\0'; Scanner in = new Scanner (System.in); do{ System.out.println("Enter your 5 single-digit lottery numbers.\n (Use the spacebar to separate digits): "); for(int i = 0; i &lt;5; i++ ) userInputs[i] = in.nextInt(); System.out.println("Your inputs: "); printArray(userInputs); System.out.println("\nLottery Numbers: "); readIn(lotteryNumbers); for(int i=0; i&lt;5; i++) { System.out.print(lotteryNumbers[i] + " "); } matchedNumbers = compareArr(userInputs, lotteryNumbers); System.out.println("\n\nYou matched " + matchedNumbers + " numbers"); System.out.println("\nDo you wish to play again?(Enter Y or N): "); repeatLottery = in.next().charAt(0); } while (repeatLottery == 'Y' || repeatLottery == 'y'); } public static void printArray(int arr[]){ int n = arr.length; for (int i = 0; i &lt; n; i++) { System.out.print(arr[i] + " "); } } public static void readIn(int[] List) { for(int j=0; j&lt;List.length; j++) { List[j] = (int) (Math.random()*10); } } public static int compareArr (int[] list1, int[] list2) { int same = 0; for (int i = 0; i &lt;= list1.length-1; i++) { for(int j = 0; j &lt;= list2.length-1; j++) { if (list1[i] == list2[j]) { same++; } } } return same; } </code></pre> <p>}</p> <p>As you'll notice, I commented out the input line because I'm not quite sure how to handle it. If I have them in an array, I should be able to compare them fairly easily I think. This is our first assignment handling arrays, and I think it seems a bit in-depth for only having one class-period on it; So, please forgive my ignorance. :P</p> <p>Edit: </p> <p>I added a new method at the end to compare the digits, but the problem is it compares them in-general and not from position to position. That seems to be the major issue now. </p>
