So I have a SEND button, a CHAT TextArea for user to input the message and a TEXT TextArea to display the message
but when I typed a messsage and clicked on the SEND button,the TEXT didn't append that new message,but it cleared the message in CHAT. That means the code walks through the line :
text.append(temp + newline);
in the
sendButtonActionPerformed
but nothing is displayed. So what's wrong here ?

Move statement JScrollPane scrollPane = new JScrollPane(text); before pack() and it will be ok. Like this:
jScrollPane1 = new javax.swing.JScrollPane();
text = new javax.swing.JTextArea();
JScrollPane scrollPane = new JScrollPane(text);

How to read file text to JList

I have a question, how can I import existed array string to jlist for each element in array, I know a lot of you guy asked it before, but mostly, I saw that how to do it with a jButton, I also heard about
DefaultListModel but it did't work
private void JListAction(java.awt.event.ActionEvent evt) {
DefaultListModel listModel = new DefaultListModel();
for (int i = 0; i < dm.getSize(); i++) {
listModel.addElement(dic.newWord.get(i).getWordExplain());
}
jList2.setModel(listModel);
}
Here is my code from GUI only

Is your Array of Strings already available, when the GUI is generated? If so, you can insert it directly into your JList by using it as a parameter.
Instead of using JList jList2 = new javax.swing.JList<>(); (as it is done in line 5 of your initComponent() method) you'd put your String[] into the brackets:
String[] data = {"a","b","c"};
JList jList2 = new javax.swing.JList<>(data);
JScrollPane pane=new JScrollPane(jList2);
In this case your ScrollPane would look something like this

Rdf and java gui

I have a job to do and I want to display results from this program in my GUI but I just can not do it, then I want a method for allowing me to see the results of this program in my graph inetreface, so I created an interface and I reserved a button displays and an area for display (JTextArea), it means when I click on button shows me it shows the results (the contents of my Rdf file). I want your help if possible and thank you in advance

If I understand you want to display entire RDF file in a text area. So if it's that what you want, you just need to read it in using a reader something like...
try{
FileReader f = new FileReader("c:\\opus_august2007.rdf");
BufferedReader b = new BufferedReader(f);
boolean eof = false;
while(! eof)
{
String lineIn = b.readLine();
if(lineIn == null)
{
eof = true;
}
else
{
mytxtarea.append(lineIn + System.getProperty("line.separator"));
}
}
}catch(Exception e){
e.printStackTrace();
}

jLabel won't print from String

I'm trying to populate a jLabel with text from a global String in NetBeans, but every time I try to print anything other than a String literal, it prints nothing. I've tried directly printing the String, and my most recent attempt used a get() method.

I believe the constructor is your issue.
public ChatWindow(int id) {
initComponents(); //otherPerson = "";
userID = id;
otherPerson = userID.toString(); //otherPerson = id;
this.setVisible(true);
}
You initialize the component before otherPerson is set. Move initComponents after setting otherPerson and it should work again.

You are calling "initcomponent" first and then initializing "otherPerson" class member. Do it like this:
public ChatWindow(int id)
{
userID = id;
otherPerson = userID.toString();
initComponents();
this.setVisible(true);
}

Netbeans: string not displaying

I would seriously advise you to take a time out, and refactor all of your code. Igonoring that in the class new8, in method decode replace this code:
new vpsfame().ac.setText(t[1].substring(1,2));
System.out.println("Lattitude: "+t[3]);
System.out.println("Direction of Lattitude: "+t[4]);
new vpsfame().ab.setText(t[3].concat(t[4]));
System.out.println("Longitude: "+t[5]);
System.out.println("Direction of Longitude: "+t[6]);
new vpsfame().bc.setText(t[5].concat(t[6]));
System.out.println("Speed over Ground: "+t[7]);
new vpsfame().cd.setText(t[7]);
With this:
//use one object, dont just create new frames
vpsfame myFrame = new vpsfame();
myFrame.ac.setText(t[1].substring(1,2));
System.out.println("Lattitude: "+t[3]);
System.out.println("Direction of Lattitude: "+t[4]);
myFrame.ab.setText(t[3].concat(t[4]));
System.out.println("Longitude: "+t[5]);
System.out.println("Direction of Longitude: "+t[6]);
myFrame.bc.setText(t[5].concat(t[6]));
System.out.println("Speed over Ground: "+t[7]);
myFrame.cd.setText(t[7]);
//Also set the frame to visible, so it can be displayed once you've done all this work.
myFrame.setVisible(true);
The problem is that:
Firstly, you are creating multiple vpsframe objects where you should only have one. It makes no sense to create 5 frames where each will have 4 empty fields. Create one object and initialise all it's fields rather than using 5 diffrent objects.
You are not tracking the objects you are creating, the garbage collector will just get rid of the, so create one object, assign it to a variable and use that.
Set the vpsfame object to visible, otherwise you will never see it.
Your code also needs refactoring, you should be using the camelCase naming convention, and classes should always begin with Capital letters.
