<pre><code> rbtnmale.setSelected(true);
 rbtnmale.setSelected(false);
</code></pre>

Based on your current code you want:

<pre><code> //rbtnmale.setSelected(false);
 rbtnfemale.setSelected(false);
</code></pre>

However you don't even need the above code in the ActionListener for either of the radio buttons. 

Instead you should be using a <code>ButtonGroup</code> and the <code>ButtonGroup</code> will manage the selected state of each radio button for you:

<pre><code>ButtonGroup group = new ButtonGroup();
group.add(btnMale);
group.add(btnFemale);
</code></pre>

You should be using <a href="https://docs.oracle.com/javase/7/docs/api/javax/swing/ButtonGroup.html" rel="nofollow noreferrer"><code>ButtonGroup</code></a>, put all of your <code>JRadioButton</code>s in it and then loop through <code>buttonGroup.getElements()</code> to find which <code>JRadioButton</code> is selected. Here is a complete example:

import javax.swing.AbstractButton;

import javax.swing.ButtonGroup;

 }

 private void initComponents() {
 //Radio buttons
 JRadioButton female = new JRadioButton("Female");
 JRadioButton male = new JRadioButton("Male");
 JRadioButton other = new JRadioButton("Other");

 female.setSelected(true);//by default, select female.

 //Add all radio buttons to a group. 
 //It will allow to only have one selected at a time.
 group.add(male);
 group.add(female);
 group.add(other);

 //Add your components to a panel, it's a good practice.
 JPanel panel = new JPanel(new FlowLayout(FlowLayout.CENTER));
 panel.add(female);
 panel.add(male);
 panel.add(other);

 JFrame frame = new JFrame("Example");
 frame.setLayout(new BorderLayout());
 frame.setLocationRelativeTo(null);

 frame.add(panel, BorderLayout.CENTER);
 frame.pack();
 frame.setVisible(true);
 }

 /**

 if (selected == null) {
 System.out.println("There is something wrong! Nothing is selected");
 return;
 }
 switch (selected.toLowerCase()) {
 case "male":

This code not work properly. When I select male, every time it select female automatically?

How to validate radio button for gender?

 rbtnmale.addActionListener(new ActionListener() {

 @Override

rbtnmale.setBounds(116, 127, 58, 23);
