Thread: Action not working

Hello, i am trying to make a program with a button that outputs Hello World and the error tells me this... Multiple markers at this line
- firstButton cannot be resolved to a variable
- The method getSorce() is undefined for the type

Here is the code

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
 
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
 
public class jframeTest {
public static void main(String args[]) {
 
	JFrame emptyWindow = new JFrame("Hello World");
	emptyWindow.pack();
	emptyWindow.setSize(550, 750);
	emptyWindow.setResizable(false);
	emptyWindow.setLocationRelativeTo(null);
	emptyWindow.setVisible(true);
	emptyWindow.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	JPanel panelOne = new JPanel();
	JButton firstButton = new JButton("Hello World");
	emptyWindow.add(firstButton);
	emptyWindow.add(panelOne);
	panelOne.add(firstButton);
    firstButton.addActionListener(new Action());
 
	}
 
public static class Action implements ActionListener {
 
	public void actionPerformed(ActionEvent e) {
		if(e.getSorce()==firstButton){
			System.out.println("It Works");
		}
 
	}
 
}
 
 
}

Welcome to the forum! Thanks for taking the time to learn how to post code correctly. If you haven't already, please read this topic to learn other useful info for new members.

Please observe Java's naming conventions which call for class names to begin with capital letters.

You also have a typo at line 30:

if(e.getSorce()==firstButton)

Update:

AND, this statement has a purpose:

emptyWindow.pack();

You should read the API to understand its purpose, and you may also then see that its purpose is only realized AFTER components have been added. Order often matters.
