Question

How do I set the text of a JLabel in Java?

Answer 1

You can set the text of a JLabel in Java using the setText() method. 

Here's an example code snippet that demonstrates how to set the text of a JLabel:

import javax.swing.*;

public class MyFrame extends JFrame {
    public MyFrame() {
        // create a new JLabel
        JLabel label = new JLabel();

        // set the text of the JLabel
        label.setText("Hello, world!");

        // add the JLabel to the JFrame
        add(label);

        // set the size and visibility of the JFrame
        setSize(300, 300);
        setVisible(true);
    }

    public static void main(String[] args) {
        new MyFrame();
    }
}
 

In this example, we create a new JLabel and set its text using the setText() method. We then add the JLabel to the JFrame using the add() method. Finally, we set the size and visibility of the JFrame.

Note that you can also set the text of a JLabel when you create it by passing a String parameter to the JLabel constructor. 

For example:

JLabel label = new JLabel("Hello, world!");
 

This will create a new JLabel with the text "Hello, world!" already set.
