What Methods Are Used to Get And Set The Text Label Displayed by a Button Object?

by

getLabel() and setLabel().

In Core Java, specifically in the context of GUI programming using Swing, the methods used to get and set the text label displayed by a Button object are:

  1. To get the text label:
    • getText(): This method retrieves the current text displayed on the button.
  2. To set the text label:
    • setText(String text): This method sets the text to be displayed on the button. You pass the desired text as an argument to this method.

Here’s a simple example:

java
import javax.swing.JButton;
import javax.swing.JFrame;public class ButtonExample {
public static void main(String[] args) {
JFrame frame = new JFrame(“Button Example”);
JButton button = new JButton(“Click Me”);

// Get the current text label
String currentText = button.getText();
System.out.println(“Current text label: “ + currentText);

// Set a new text label
button.setText(“Press Me”);

// Display the updated text label
System.out.println(“Updated text label: “ + button.getText());

frame.getContentPane().add(button);
frame.setSize(300, 200);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}

In this example, getText() is used to get the initial text label, and setText("Press Me") is used to set a new text label for the button.
