Hi All,

I'm trying to add a JLable 'jLable2 to another JLabel 'jLabel1'. But
jLabel2 isn't getting displayed.

My code

<software> Instructions for a computer in some programming
	language, often {machine language}.  The word "code" is often
	used to distinguish instructions from {data} (e.g. "The code
	is marked 'read-only'") whereas "{software}" is used in
	contrast with "{hardware}" and may consist of more than just
	code.

is

import JAVAx.swing.*;

public class

1. <programming> The prototype for an {object} in an
	{object-oriented language}; analogous to a {derived type} in a
	{procedural language}.  A class may also be considered to be a
	set of objects which share a common structure and behaviour.
	The structure of a class is determined by the {class
	variables} which represent the {state} of an object of that
	class and the behaviour is given by a set of {methods}
	associated with the class.

	Classes are related in a {class hierarchy}.  One class may be
	a specialisation (a "{subclass}") of another (one of its
	"{superclasses}") or it may be composed of other classes or it
	may use other classes in a {client-server} relationship.  A
	class may be an {abstract class} or a {concrete class}.

	See also {signature}.

	2. <programming> See {type class}.

	3. <networking> One of three types of {Internet addresses}
	distinguished by their most significant bits.

	3. <language> A language developed by the {Andrew Project}.
	It was one of the first attempts to add {object-oriented}
	features to {C}.

LabelTest extends JFrame {

public LabelTest(){

setDefaultCloseOperation(JAVAx.swing.WindowConstants.EXIT_ON_CLOSE);
JLabel jLabel1 = new JAVAx.swing.JLabel();
jLabel1.setText("jLabel1");
JLabel jLabel2 = new JLabel();
jLabel2.setText(" TEXT ");
jLabel1.add(jLabel2);
getContentPane().add(jLabel1, JAVA.awt.BorderLayout.CENTER);
pack();
} public static void main(String args[]) {
LabelTest lTest = new LabelTest ();
lTest.setSize(400,300);
lTest.setVisible(true);
}

}

Please advice on how I can make jLabel2 visible.
Thanks in advance

Why?

..But

Try this variant that adds both JLabels directly to the JFrame.
If that isn't the effect you are after, there are many alternatives,
including adding them both to a JPanel that is itself added to
one particular area of the BorderLayout of the JFrame.

<sscce>
import JAVA.awt.BorderLayout;
import JAVAx.swing.*;

public class LabelTest extends JFrame {

public LabelTest(){

setDefaultCloseOperation(
WindowConstants.EXIT_ON_CLOSE);
JLabel jLabel1 = new JLabel();
jLabel1.setText("jLabel1");
JLabel jLabel2 = new JLabel();
jLabel2.setText(" TEXT ");
//jLabel1.add(jLabel2);
getContentPane().add(
jLabel1, BorderLayout.CENTER);
getContentPane().add(
jLabel2, BorderLayout.EAST);
pack();
}

public static void main(String args[]) {
LabelTest lTest = new LabelTest ();
lTest.setSize(400,300);
lTest.setVisible(true);
}
}
</sscce>
