KeyPressed event is called multiple times

I have a jTextField and added a key listener to it. So, if I type something and press Enter key, the keypressed event will be called and then I will save whatever is typed.

But, if I press Enter key, it is called 3 times.

tPatientName.addKeyListener(new java.awt.event.KeyAdapter() {
		@Override
		public void keyPressed(java.awt.event.KeyEvent e) {
			  if(e.getKeyCode() == KeyEvent.VK_ENTER) {
				  System.out.println("Saved Successfully");
			  }
		}
	});	

Console output:

Saved Successfully
Saved Successfully
Saved Successfully

I don't know what is wrong in my code.
Thanks in advance.

I created a MRE based on what you're telling us and it works without any problems whatsoever. Feel free to compare whatever mysterious code that you can't share with us with my little example.

import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;

public class EnterKeyTest
{
    JFrame frame;
    JPanel panel;
    JTextField tPatientName;
    
    public EnterKeyTest()
    {
        initGUI();
    }
    
    public static void main(String[] args)
    {
        EnterKeyTest e = new EnterKeyTest();
    }
    
    private void initGUI()
    {
        frame = new JFrame();
        panel = new JPanel();
        
        tPatientName = new JTextField(15);
        tPatientName.addKeyListener(new KeyAdapter()
        {
            @Override
            public void keyPressed(KeyEvent e)
            {
                if(e.getKeyCode() == KeyEvent.VK_ENTER)
                {
                    System.out.println("Saved Successfully");
                }
            }
        });
        
        panel.add(tPatientName);
        frame.add(panel);
        
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);
    }
}

I found out the reason for it. I have declared the jTextField as static.

I had it like this:

public static JTextField tPatientName= new JTextField();

After removing the static keyword it worked.

But, why static keyword do this?

Does changing keyPressed() to keyReleased() help?
