    <p>Firstly,you can use enums instead of strings as mentioned by Jack above. Eg</p> <p>private enum Objects{ Rock(1),Coin(8),Med(45)...and so on } </p> <p>In your array, you may store these objects as numbers rather than strings.</p> <p>eg:</p> <pre><code> boolean stopFlag=false; do{ //check each element of your world array with the enum and draw it for(int i=0;i&lt;yourObjectsArray.length;i++) { for(int j=0;j&lt;yourObjectsArray[i].length;j++){ switch(yourObjectsArray[i][j]) { case Objects.Rock: drawRock(i,j); break; case Objects.Coin: drawCoin(i,j); break; //and so on.... } } } //you can also put this into a separate function as drawWorld() and pass the objects. //Key press checking logic here. If user presses exit key [esc] then you set the stopFlag as true if(keypress==KEY_ESC){ stopFlag=true;} }while(!stopFlag); </code></pre> <p>An example of Draw Rock: </p> <pre><code>private void drawRock(int i,int j){ //i and j are the cols and row values so you need to resolve them to coordinates. //I am assuming u have a 800*600 screen and you mentioned that your world is 100x100 array. Then each of your object is 8*6 units in size so xCoord=i*8; yCoord=j*6; //So if you have to draw a rock on [10][15] it will resolve as //xCoord=10*8-&gt; 80 //yCoord=15*6-&gt; 90 so it will draw your rock in (80,90) on the screen //Now you can either open the rock image from your disk now or u maintain one instance of rock at the beginning of the program so that you can use the same image later rather than opening it everytime you encounter a new Rock object in your array.For now I will open it here. String path = "C:\\YourGameDirectory\\rock.jpg"; URL url = new File(path).toURI().toURL(); BufferedImage rockImg = ImageIO.read(url); //draw it to the screen now if you have the graphics instance. yourUIPanel.getGraphics().drawImage(rockImg,xCoord,yCoord,yourUIPanel); // You may find many resources that teach you how to draw an image on the screen in Java. You may repeat the same for all the objects. } </code></pre> <p>I hope the above codes helped you a-bit. If not,its my bad.</p> <p>You can try <a href="http://www.youtube.com/watch?v=86sDrOcNGUA" rel="nofollow" title="Youtube Series">this</a> tutorial series to get started. Although its in C , it has concepts that will help u acheive what you have mentioned above.</p>

    1. COThank you very much for your help. I spent the past few hours trying to understand what you wrote, and I finally managed to come up with a good method, though it is different from yours. The coordinate positioning tips helped me a lot.

    3. COI am sorry for my crappy english in my answer.. I didnt recheck what I had written.. :D U can use another array for such overlapping objects. First draw the background objects and then draw the overlapping objects that are transparent. I am really not an expert on this so I advise you to do some more research on this. And do look at the Processing java library,it will make things much easier for you.

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.
