Swing JRadioButton

To use this component, it's needed to use ButtonGroup:

import java.awt.*:

import javax.swing.*;

public Main{

   public static void main(String[] args){

        JFrame frame = new JFrame("Radio Button");

        JRadioButton rbApel = new JRadioButton("Apel");

        JRadioButton rbNanas = new JRadioButton("Nanas");

        JRadioButton rbJambu = new JRadioButton("Jambu"):

        ButtonGroup group = new ButtonGroup();

        group.add(rbApel);

        group.add(rbNanas);

        group.add(rbJambu);

        frame.add(rbApel);

        frame.add(rbNanas);

        frame.add(rbJambu);

        frame.setSize(400, 300);

        frame.setLocation(200, 100);

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        frame.setVisible(true);

   }

}
