Re: Get imports for program

Well, I was addressing Andrew's comment about leaving a browser window
open to the Java doc. I don't don't that, I use Google.

However, for your specific question, if I take the code you posted in
your original post, and paste it into NetBeans, I then press
Shift-Control-I and NetBeans automatically adds the following for me:

import java.awt.Component;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.JFrame;

Nice, eh?

You can read more about this feature here:

<http://www.testwww.netbeans.org/kb/60/java/editor-tips.html#Managing-the-Import-Section>


For Google, the phrase I use is "java <classname> 6" where <classname>
is the name of the class I'm looking for. This usually take me right to
the most recent Java doc.

Here's the final code that NetBeans gave me, after I pasted your OP and
pressed Ctl-Shift-I:

package fubar;

import java.awt.Component;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.JFrame;

public class ImportTest {
}

/**
  *This class demonstrates how to load an Image from
  * an external file
  */
@SuppressWarnings("serial")
class LoadImageApp extends Component {

     BufferedImage img;

     public void paint(Graphics g) {
         g.drawImage(img, 0, 0, null);
     }

     public LoadImageApp() {
         try {
             img = ImageIO.read(new File(
                     "image/GridImage.jpg"));
         } catch (IOException e) {
         }
     }

     public Dimension getPreferredSize() {
         if (img == null) {
             return new Dimension(100, 100);
         } else {
             return new Dimension(img.getWidth(null),
                     img.getHeight(null));
         }
     }

     public static void main(String[] args) {
         JFrame f = new JFrame("Load Image Sample");
         f.addWindowListener(new WindowAdapter() {

             public void windowClosing(WindowEvent e) {
                 System.exit(0);
             }
         });
         f.add(new LoadImageApp());
         f.pack();
         f.setVisible(true);
     }
}
