I am having trouble with getting a user input once they enter it in to a JTextArea and then storing it in to a string value. See, I wanted the user to enter an answer in to the JTextArea, and then once I store it in to a string value, I would be able to use it later. I wanted to after storing the variable to print it on to a JLabel, but nothing is showing up... Heres my code.
static String usera[]= new String [10];
for (int i=0; i< usera.length; i++) {
//These are the JTextArea names
usera[0]= Question1.getText();
usera[1]= Question2.getText();
[Code].....
I already initialized the JLabels earlier in my code, and I did not feel the need to post all my code here. This is where I am trying to get the string variable and then printing it out.

I am setting text to textarea from textfield. It works perfectly. My challenge, however, is setting texts with spaces in-Between them. For example, what I observe is:Amount23 instead of: Amount 23. Is it possible to automatically create word space while setting texts?

I am making use of NetBeans IDE 8.0 to build a GUI. The idea is that I set multiple values received from textfields to textarea. This will enable me print the work. But ONLY ONE value from textfields is set(appear on textarea); the others do not appear at all. Below is example of what I mean:
String s = jTextField1.getText();
JTextArea1.setText(s);
String x =
jTextField2.getText();
JTextArea1.setText(x);
Only one is being set. The rest are not.

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.

int bytesRead;
while ((bytesRead = din.read(buffer)) > 0 ) {
byte[] nData = new byte[data.length + bytesRead];
System.arraycopy(data, 0, nData, 0, data.length);
System.arraycopy(buffer, 0, nData, data.length, bytesRead);

I have a java swing application.
1. The human user of my application asks it to fire up a scanner which scans a paper document. The document is a filled in form.
2. The application then displays the scanned image to the human user.The image is displayed in a JScrollPane since it may be larger than the scroll pane.
3. The human user needs to locate a certain item in the form, for example a social security number, and enter it into a field in a data entry screen.Note that the image and the field appear on the same screen.
Of-course the social security number always appears in the same location in the image. Also the image needs to be the appropriate magnification and resolution to allow the human user to easily read and understand the item he is searching for in the image.
What is the best way to present the scanned image to the user such that he immediately sees the item he requires and can enter it into the data entry field.

I have added the image in the src and bin directories and cross-checked that the name of the image file is correct..Here is the main class
import javax.swing.*;
public class apples
{
public static void main(String args[])
{
JFrame frame = new JFrame();
MyDrawPanel wid = new MyDrawPanel();
frame.add(wid);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
frame.setSize(300,300);
}
}
and here is the class that does the image adding part
import java.awt.*;
import javax.swing.*;
public class MyDrawPanel extends JPanel
{
public void paintComponent(Graphics g)
{
Image image = new ImageIcon("b.png").getImage();
g.drawImage(image,20, 20, this);
}
}

Trying to get an image to display in a GUI.
try {
ByteArrayInputStream in = new ByteArrayInputStream(
transferWorker.bOutput
.toByteArray());
BufferedImage bufferedImage = ImageIO
.read(in);
[Code] ....
But nothing is happening in the GUI. I have stepped through and bufferedimage contains the data, but its not being displayed. Whats happening is, an image is being transmitted to serial port of laptop, so i'm taking it in and storing it in a BufferOutputStream and then trying to open it in my GUI class.

I have a GUI with several buttons and I'm using NetBeans GUI Builder to do. At the click of one of these I would like for it to open another frame containing a picture. So I associate a listener (actionPerformed) the button and when clicked it opens actually post the new frame.
In the new frame I waxed a JLabel and then I associate the image of the label. I saw that to do that NetBeans generates this code:
label.setIcon(new javax.swing.ImageIcon(getClass().getResource("/img/tree.png")));
My problem is that the picture is overwritten several times during the execution of the program is not changed yet in the frame. That is, in the new frame is always displayed an old version of the image.
I have an image that is created every time I click on the button (it always has the same name and same path). Basically I have a generic tree on which I perform the operations (add, remove, etc..). When I click on the button I call a method that generates the image of the tree (using Graphviz). So I have one image that changes over the time...
How can I do so that the image is always up to date?
The Code:
package View;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JLabel;
public class AlberoIpotesi extends javax.swing.JFrame {
[Code] ....

I can't find any resource on the net about a simple Java code just to move a gif image left or right. I've already accomplished the up, down, and center and they're working fine, thus, I'm still struggling with moving the image left or right. Here's the code.
public class MoveIt extends Applet implements ActionListener
{
private Image cup;
private Panel keypad;
public int top = 10;
public int left = 10;
[Code] ....
I remember in Visual BASIC it's easily achieved by NameOfImage.left = NameOfImage.left - 10 to move left and NameOfImage.left = NameOfImage.left + 10.

I simply want to paint an image on my frame, just once each time the paint() method is called, but how to call the paint method in any good way. This is how it looks:
import java.awt.AWTException;
import java.awt.Dimension;
import java.awt.Graphics2D;
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
[Code] ....
I have a frame in another class, and from my assumption I need to somehow tell my paint method to paint on that specific frame right?

I'm currently following this Java tutorial:[URL]
I'm at the Image part of this chapter and I wrote/copied these 2 classes:
[URL]
The error:
Exception in thread "main" java.lang.NullPointerException
at javax.swing.ImageIcon.<init>(Unknown Source)
at image.Board.<init>(Board.java:17)
at image.Image.<init>(Image.java:10)
at image.Image.main(Image.java:20)
I'm fairly certain the problem is the path in this piece of code:
ImageIcon ii = new ImageIcon(this.getClass().getResource("C:GebruikersKristofferworkspaceImagessrcimageNature.jpeg"));
I've done some research and found that I should place the image in the same folder as my .java files, which I did [URL] but the problem still persists.

I am fairly new to Java. I am trying to learn some image manipulation basics. I have searched the web endlessly and made numerous attempts but I cannot seem to get a darn image to display. This code is my latest attempt in Eclipse. The file I am using is chairangle.jpg which is is the src folder of the package I am working in in Eclipse. I am on Windows 8.
import java.awt.*;
import javax.swing.*;
import javax.swing.ImageIcon;
public class otherimg extends JFrame
{
public static void main(String args[]){
JFrame f = new JFrame();
ImageIcon image = new ImageIcon("image/chairangle.jpg");
JLabel label = new JLabel("", image, JLabel.CENTER);
JPanel panel = new JPanel(new BorderLayout());
panel.add( label, BorderLayout.CENTER );
f.pack();
f.setVisible(true);
}
}
