    <p>I'm quite new to Java, but getting into it. However, I can't wrap my head around why this example, which I found here, does not work: </p> <p>At start of class: </p> <pre><code>String[][] spritesPaint = new String[20][20]; </code></pre> <p>In method:</p> <pre><code>for (int funct1 = 0; funct1 &lt;= 2; funct1++) { if (funct1 == 0) { for (int funct2 = 0; funct2 &lt; rEnemyNumber; funct2++) { spritesPaint[0][funct2] = new Integer(rEnemyY[funct2]) .toString(); spritesPaint[1][funct2] = rEnemyGraphic[funct2]; } } else if (funct1 == 1) { Arrays.sort(Integer.valueOf(spritesPaint[0].toString()), new Comparator&lt;Integer[]&gt;() { @Override public int compare(final Integer[] entry1, final Integer[] entry2) { final Integer time1 = entry1[0]; final Integer time2 = entry2[0]; return time1.compareTo(time2); } }); } else if (funct1 == 2) { for (int funct3 = 0; funct3 &lt; rEnemyNumber; funct3++) { if (rEnemyCheck[funct3] == true) { nextPaint = getImage(base, rEnemyGraphic[funct3]); System.out.println("Next: " + nextPaint); g.drawImage(nextPaint, rEnemyX[funct3] + worldCenterX, rEnemyY[funct3] + worldCenterY, this); } } } } </code></pre> <p>Basically, what I want to do is have a two dimensional array where I store Y position of object on the screen and an image path also related to that object, then sort it by the Y position integer. This should allow me to paint elements to the screen in the correct order for an isometric perspective.</p> <p>However, I keep getting this error: </p> <pre><code>The method sort(T[], Comparator&lt;? super T&gt;) in the type Arrays is not applicable for the arguments (Integer, new Comparator&lt;Integer[]&gt;(){}) </code></pre> <p>Please help me, I've been twisting my brain for hours trying to understand why I get this error now.</p>

    1. COThe first paramater of `Arrays.sort()` must be an array. You are passing an `Integer`.

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.
