    <p>My programming assignment was to print an array with 10 random integers and then have 4 lines with different outputs (every even element, reverse order, etc.)</p> <p>The code itself works fine (as far as I can tell) but one problem I'm having is that I had to put a System.out.println(""); before every line in order for the lines to look correct. </p> <p>Initially, when I had it System.out.println("[LINE 1]....") *for loop * System.out.print("arr[i] + ", ") *close for loop * it printed each integer on a separate line instead of all on one line. Am I missing something here?? Can anyone help? </p> <p>Here's my code:</p> <pre><code>import java.util.*; public class RandomInteger { public static void main(String[] args){ Random random = new Random(); int arr[]=new int[10]; System.out.print("The array of random numbers: "); for (int i = 0; i &lt; arr.length; i++) { arr[i] = random.nextInt(50); System.out.print(arr[i] + ", "); } System.out.println(""); System.out.print("[LINE 1] Elements at an even index: "); for (int i = 0; i &lt; arr.length; i++) { if(i%2==0){ System.out.print(arr[i]+" (at index "+i + "), "); } } System.out.println(""); System.out.print("[LINE 2] Every even element:"); for (int i = 0; i &lt; arr.length; i++) { if(arr[i]%2==0){ System.out.print(arr[i] + ", "); } } System.out.println(""); System.out.print("[LINE 3] Elements in reverse order: "); for(int i=arr.length-1;i&gt;=0;i--){ System.out.print(arr[i] + ", "); } System.out.println(""); System.out.print("[LINE 4] First Element is: "+arr[0]+" and Last ELement is: "+arr[arr.length-1]); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
