Setting a JLabel visible on JRadioButton click

I tried setting JLabel to being visible only after I select a certain JRadioButton. The program is getting an error if I set lblNewLabel_1.setVisible(true) in the action performed of a radio button. It worked with the text field, but with this not. What can I do? Is it different with the label? Is there any advice someone can offer me?

It's because your label is declared in function context, put the declaration next the textbox declaration and it should work fine

How to set alignement in JTextPane?

I'm trying to make a chat application with Java; I chose to use JTextPane to display messages, because I read that it supports alignment. My problem is that I want to know how to align text in it. Like when I'm the sender, the sent message will be aligned in right; and when I'm the receiver it will be aligned in left.
Here is the code I wrote, but it aligns the whole text in right or left:

Does anyone know how to do that??

In "setTextToTextPane" in your code sample you're inserting "txt="\n"". This should be ""txt + "\n". Without this change it won't printing anything.
What you're doing in "setTextToPane" is correct in terms of setting the attributes. If you do a unit test it correctly positions the text left or right depending on the value of "received".

make sure that Inventory extends JPanel
this makes Inventory to behave as a subclass of a JPanel, and thus you can use it in the same way.

InvokeLater not outputting updating value

I'm using invokelater to update a value on button click, but the value is only changing when I run another instance of the GUI. I'm running the invokelater method outside the main method so I'm not sure why the value won't update. Any help is appreciated.
private void threadStart() {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
testLabel.setText(CN);
}
});
}
I'm using the created method here:
searchComputerButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
threadStart();
String line;
BufferedWriter bw = null;
BufferedWriter writer = null;
try {
writer = new BufferedWriter(new FileWriter(tempFile));
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
etc...
