    text
    copied!<p>As an exercise for my Java course in Uni this morning, I had to write a small program to ask the user to input some details, then print them back. I've since finished writing it, but I ran into a strange problem along the way.</p> <p>See the code below:</p> <pre><code>import java.util.Scanner; public class Scanner_Exercise { public static void main (String[] args) { Scanner keyboardIn = new Scanner(System.in); int accountId; String accountName; float accountBalance; System.out.println("Account ID: "); //Line 13 accountId = keyboardIn.nextInt(); //Line 14 System.out.println("Account name: "); //Line 16 accountName = keyboardIn.nextLine(); //Line 17 System.out.println("Account balance: "); accountBalance = keyboardIn.nextFloat(); } } </code></pre> <p>When this program runs, line 17 (refer to comments) is skipped; <code>Account name:</code> is printed, but the user is not given the opportunity to enter the information, as if that line of code was commented out. No errors are thrown. The output looks like this:</p> <blockquote> <p>Account ID:<br> 2<br> Account name:<br> Account balance:</p> </blockquote> <p>However, if I switch lines 13 and 14 with 16 and 17, like as follows, the program runs fine, and no lines are skipped.</p> <pre><code>System.out.println("Account name: "); //Line 16 accountName = keyboardIn.nextLine(); //Line 17 System.out.println("Account ID: "); //Line 13 accountId = keyboardIn.nextInt(); //Line 14 </code></pre> <p>Why is the line 17 being skipped in the first case, but not the second?</p> <p>If it's somehow relevant, I am using JDK 6 Update 18, and TextPad 5.3.1.</p>
