JLabel in Java Swing

The JLabel class is a Swing component for placing text in a container. It is used to display a single line of read-only text. The text can be changed by an application and can’t be edited by the user directly. It is a child class of JComponent class.

A display area for a short text string or an image, or both. A label does not react to input events. A JLabel object can display either text, an image, or both. You can specify where in the label’s display area the label’s contents are aligned by setting the vertical and horizontal alignment. By default, labels are vertically centered in their display area. Text-only labels are leading edge aligned, by default; image-only labels are horizontally centered, by default.

You can also specify the position of the text relative to the image. By default, the text is on the trailing edge of the image, with the text and image vertically aligned.

public class JLabelDemo {
	public static void main(String[] args) {
		JFrame frame = new JFrame("JLabel Demo");
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setSize(300, 300);
		frame.setVisible(true);
		frame.setLayout(null);
		// Adding Name label to frame
		JLabel name = new JLabel("Name:");
		name.setBounds(50, 100, 100, 20);
		frame.add(name);
		// Adding Value label to frame
		JLabel value = new JLabel("Coder Sathi");
		value.setBounds(100, 100, 100, 20);
		frame.add(value);
	}
