    <p>This is the code I have now, it compiles fine but gives me the above error when I try to run it.</p> <pre><code>import java.awt.*; import java.awt.event.*; import java.awt.Robot; import java.awt.AWTException; import java.awt.Rectangle; import java.awt.Color; import java.awt.Toolkit; import java.awt.image.BufferedImage; import java.io.File; import java.io.IOException; import javax.imageio.ImageIO; public class GunningBot { public static void main(String[] args) throws Exception { Robot robot = new Robot(); Color color1 = new Color(195, 174, 196); { Rectangle rectangle = new Rectangle(0, 0, 1075, 700); { BufferedImage image = robot.createScreenCapture(rectangle); search: for (int x = 0; x &lt; rectangle.getWidth(); x++) { for (int y = 0; y &lt; rectangle.getHeight(); y++) { if (image.getRGB(x, y) == color1.getRGB()) { robot.mouseMove(x, y); break search; } } } } } robot.delay(0); robot.mousePress(InputEvent.BUTTON1_MASK); robot.delay(0); robot.mouseRelease(InputEvent.BUTTON1_MASK); robot.delay(15); robot.mousePress(InputEvent.BUTTON1_MASK); robot.delay(0); robot.mouseRelease(InputEvent.BUTTON1_MASK); robot.delay(1500); robot.mouseMove(510, 440); //DO THIS BOTTOM LEFT robot.mousePress(InputEvent.BUTTON1_MASK); robot.mouseMove(500, 140); //MOVE TO LEFT 5 PXLS robot.mouseRelease(InputEvent.BUTTON1_MASK); robot.delay(250); robot.mouseMove(500, 370); //DO THIS TOP RIGHT robot.mousePress(InputEvent.BUTTON1_MASK); robot.mouseMove(510, 370); //MOVE TO RIGHT 5 PXLS robot.mouseRelease(InputEvent.BUTTON1_MASK); robot.delay(250); robot.mouseMove(700, 440); //DO THIS RIGHT CORNER MOVE LEFT 5 robot.mousePress(InputEvent.BUTTON1_MASK); robot.mouseMove(690, 440); //MOVE TO LEFT 5 PXLS robot.mouseRelease(InputEvent.BUTTON1_MASK); robot.delay(250); robot.mouseMove(315, 370); //DO THIS LEFT CORNER MOVE RIGHT 5 robot.mousePress(InputEvent.BUTTON1_MASK); robot.mouseMove(320, 370); //MOVE TO RIGHT 5 PXLS robot.mouseRelease(InputEvent.BUTTON1_MASK); } } </code></pre> <p>I have found many example fixes that go on about over extending the Array and so on but I don't use an array. So I do not understand how to fix this error for this script. Any help at all would be amazing.</p> <p>The full error is:</p> <blockquote> <p>exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0 at GunningBot.main(GunningBot.java:39)</p> </blockquote> <p>bufferimage uses a Raster, could this be the problem? rectangle is just setting the rectangle of the screen to get a screenshot of.</p> <p>Also I'm editing the code with Notepad++ and don't know how to set an exception without eclipse.</p>

    1. COWhat does the stack trace look like? That will tell you what is raising the exception. Most likely the BufferedImage or Rectangle uses an array internally, and one of your calls like `image.getRGB(x,y)` or `robot.mouseMove(x,y)` is causing it... but it would save a lot of time if you could just, you know, tell us.

    2. COCould you clean up your code a little bit? You have extra braces and the weird spacing makes it very hard to read. I also suspect the reason you are getting a array index out of bounds exception may be due to scope issues.

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.
