    <pre><code>int [] f = {1,2,3,4,5,5,4,3,2,1}; int [] b = {6,1}; System.out.println(Arrays.toString(hide(f,b))); public static int [] hide(int [] front, int [] back) { int temp; int extraTemp; int nextTemp = 0; int [] hiddenAt = new int[front.length]; //int [] shownAt = new int[front.length]; for(int x = 0; x &lt; front.length; x++){ for(int y = 0; y &lt;= back.length; y++){ temp = x; if ((back.length &gt; front.length) || (front[x] &lt; 0 || back[y] &lt; 0) || (front.length &lt; 1 || back.length &lt; 1)) { System.exit(0); } if (y &lt; back.length - 1){ nextTemp = Math.abs(back[y + 1] - front[x + 1]); } else { nextTemp = 0; } if (front[x] &gt; back[y]) { System.out.println(temp); } else if (front[x] &lt; back[y] &amp;&amp; y &gt;= back.length - 1 ) { extraTemp = back[y] - front[x]; if (extraTemp &gt; nextTemp){ extraTemp = nextTemp; } System.out.println(extraTemp); } else if (front[x] &lt; back[y]) { extraTemp = back[y] - front[x]; if (extraTemp &gt; nextTemp){ extraTemp = nextTemp; } System.out.println(extraTemp); } } } return hiddenAt; } </code></pre> <p>The <code>println</code>'s are being substituted in to see the values that are being produced. They will be <code>hiddenAt[z] = temp;</code> when I figure out the values to be correct.</p> <p>I need it to compare <code>front[0]</code> with <code>back[0]</code> then <code>front[1]</code> with <code>back[1]</code>, etc. After that, it will shift over one: <code>front[1]</code> with <code>back[1]</code> then <code>front[2]</code> with <code>back[2]</code> until the end of <code>front[]</code>. I want to find out where the lowest difference is. (In this case when the number in the []'s is 4 and 5.)</p> <p>I get two errors, one saying line 39 if ((back.length > front.length) || (front[x] &lt; 0 || back[y] &lt; 0) || (front.length &lt; 1 || back.length &lt; 1)) { System.exit(0); }</p> <p>is wrong and that line 9 is wrong as well. public class 2 { public static void main(String[] args) {</p> <pre><code> int [] f = {1,2,3,4,5,5,4,3,2,1}; int [] b = {6,1}; System.out.println(Arrays.toString(hide(f,b))); } </code></pre> <p>the exact error is:</p> <pre><code>Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2 at hw2.hide(hw2.java:39) at hw2.main(hw2.java:9) </code></pre>

    3. COI'm getting an error but I want a printed array of {-4, -5} (the numbers corresponding to the index number on the front array where the difference between the two is minimized) the negative signs just mean that the difference there is NOT 0.

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.
