    <p>You're using the same speedX and speedY variable for both of the balloons. Give them their own speed variables.</p> <p>Also, the reason why the balloons "wig out sometimes" is that when you choose a random direction, you don't specify that it can't be in the direction that you're trying to get them to go away from.</p> <p>To fix that issue, I'd suggest that you create a moveRandomDirection method for each balloon, an pass in a value that represents which edge they have hit. Then restrict the direction they can move to be any of the other directions.</p> <p>Try this:</p> <pre><code>public void moveBalloonOneInRandomDirection(int whichEdge) { double direction = 0; switch(whichEdge) { case(0): // Top edge direction = Math.random() * Math.PI + ONLY_ALLOW_DOWN_VAL; case(1): // Left edge direction = Math.random() * Math.PI + ONLY_ALLOW_RIGHT_VAL; case(2): // Bottom edge direction = Math.random() * Math.PI + ONLY_ALLOW_UP_VAL; case(3): // Right edge direction = Math.random() * Math.PI + ONLY_ALLOW_LEFT_VAL; } double direction = Math.random() * 2.0 * Math.PI; double speed = 3.0; speedX1 = (int) (speed * Math.cos(direction)); speedY1 = (int) (speed * Math.sin(direction)); } </code></pre> <p>Then in your if statements, you would have something like this:</p> <pre><code>if (img1.getX() &gt; APPLET_WIDTH - 50) // Right edge { moveBalloonOneInRandomDirection(3); } </code></pre> <p>You should probably also use constants, so that instead of the "magic numbers", you would have </p> <pre><code>private static final int RIGHT_EDGE = 3; ... moveBalloonOneInRandomDirection(RIGHT_EDGE); </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.
