Sir, I'am new to Swing Programming. I have to create an application where an image is displayed on one Label. The same image has to be split in parts and stored in database pert wise. Later the user has to retrieve the entire image by viewing a small part of the image. I have already displayed the full image on the Label, now i don't know how to split the image and store it part wise in the database.

I now know the basics of JSP and Servlets and I am going to make my own web app (shopping cart).I am having great difficulty in making a blue print for my code. But, I don't know if my blue print is useful or even missing something. where I can learn a formal process to make blueprints (not algorithms or flowcharts) for my code/web app ? I want to be able to make such amazing blueprints, that a beginner coder could simply follow the requirements and do all the coding himself.
What I did so far -
1 - Finalize a small list of features in the app.
2 - Identify all the entities or classes needed for the app - Customer, Product, ShoppingCart, etc.
3 - A list of all the web-pages/servlets/jsp's that the app might require.
I wonder if I can start coding right away. I hope that I have not missed something which will bite me later and will require a whole rewrite of the code.

So I am making a basic game and i am loading the images as such :
try {
background = ImageIO.read(new File(res/textures/bg.jpg"));
buildingManager.getButton().setCupcake_normal(ImageIO.read(new File("res/textures/cupcake normal.png")));
buildingManager.getButton().setCupcake_clicked(ImageIO.read(new File("res/textures/cupcake clicked.png")));
} catch (IOException e) {
e.printStackTrace();
}
A lot of sites say i have to add the folder where the folders are in as an class folder. So i did that but i dont get the same icon with the folder. i get this instead : code.PNG
Also i see the images inside the exported jar but they cant be reached, how do i fix this?

make the keylistener "listen" across the entire application? Currently whenever I've used it I have always attached it to something else, like a JTextField or the like. However that doesn't work all that well if I for example want to close down the current JDialog by pressing escape, because no object that has the keylistener attached to it is currently focused.
When I searched around for the answer if found similar questions on stackoverflow, but those seemed to focus on listening globally, even when the application itself is not focused, which isn't quite what I want.
Here is a simple piece of code that I'm currently experimenting with:
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.io.IOException;
import java.security.spec.InvalidKeySpecException;
[Code].....
It's supposed to simply create a frame and give me a message whenever I press the A or D buttons, as well as notify me whenever they are released. As of currently it obviously doesn't work because the keylistener hasn't been attached to anything, but that's also where I'm unsure of how to proceed.

I'm creating UI's that run on top of backend tools that can run from seconds to days and output GB's of generated data (imagine running tar on the Google servers).
I understand how to execute my backed tools using a runtime process and how to interact with them, and running a simple text as a command line Java app works as expected. The issue occurs when I wrap the code in a JavaFX frount end UI try to update the UI elements in a reasonable manner. If I simply use System.out.println() as in the command line version, I see the output from my task. However, simply trying to put that same output into a TextArea using .appendText() doesn't update the TextArea until the background process completes.
I see all sorts of clippings relating to Task, CreateProcess, invokeLater, updateProgress, but none of them seem to solve their original posters' question (nor mine at this point).

I have java program that I am debugging with NetBeans. In it I open a serial com port. It seems that if I exit the program the serial port is not closed so I cannot get the port the next time I start the program.
Is there a way I can detect that either the user clicked the "X" in the upper ight of the GUI or I clicked the "Stop Button" in NetBeans?

I just started learning Java, I was asked to write a simple program that prints a message if it encounters the number 7 or its multiple.
This should be achievable using simple loops and simple operations...
Here is my attempt:
Java Code:
Scanner scan = new Scanner(System.in);
int i, j, temp;
i = scan.nextInt(); // Awaiting user input
j = scan.nextInt(); // Awaiting user input
if (i > j){ // i = 10 j = 0
temp = i; // temp = 10
[Code]...
Now it works fine for numbers that are less than 70...
Example for output with i = 15, and j = 25:
Java Code:
15
16
!!!
18
19
20
!!!
22
23
24
25 mh_sh_highlight_all('java');
I am not sure what to do in case if for example 'i' and 'j' are very big numbers
I mean, I need it to detect the 7s even if it in the thousands place, actually - no matter how big is the number... So far I only made it to work for numbers that are less than 70...

I'm trying to place a try/catch into a Actionlistener that will detect other characters other than alpha.
private class printbuttonHandler implements ActionListener {
public void actionPerformed(ActionEvent e) {
//Object src = namesinput;
//String message = "Insert Message Here";
notesinput.setText("");
JOptionPane.showMessageDialog(null, notesinput, "Receipt",
JOptionPane.PLAIN_MESSAGE);
}
I'm not even sure if I'm trying to place it in the correct area in the code. However I like to perform this prior to the receipt being displayed so if there a issue the user can correct this before the final receipt has been sent .......

My project builds a war. In the war there is a jar A which provides the implementation I1 of interface I. I1 is injected in a JSF controller. There is an optional jar B which provides another implementation I2 of interface I. I2 has an higher priority than I1. Is there a possibilty to achieve when jar B is present in the war I2 is injected. I tried it with @Alternative on I2 with an entry in beans.xml as alternative in jar B without success. I1 is injected. Something like a priority would be necessary. Or probably I am on a wrong way and there's another one that fits for my use case?

I have a JTable with 5 columns, named: "ID", "Name", "UnitPrice", "Qty", and "Total". Only the columns UnitPrice and Qty are editable by the user. When, for example, for a row in the JTable, the user types 5000 in the UnitPrice column, and types 15 in the Qty column, I would want that when he types the first character in the Qty column (i.e. the character 1) in the Qty column, the Total column displays 5000*1, in other terms 5000.
And when the user types the second character in the Qty column, i.e the character 5, after having typed 1, the Total column should display 5000*15, in other terms 75000. So, to say it concisely, I would want that the Total column refreshes accordingly each time the user types a character in the Qty column. I have tried to use the MouseClicked event of the JTable, but noticed that that does not solve my problem. is there an event I should use to refresh my Total column? Or should I proceed in another fashion?
