Cannot Find Symbol Error

[NajwaMy]

I keep on getting this error

error: cannot find symbol
if(e.getSource==btn1);
symbol: variable getSource
location : variable e of type ActionEvent

here's the code

import java.awt.event.*;
import javax.swing.*;
import java.awt.*;

public class Name extends JFrame
implements ActionListener
{
JButton btn1=new JButton("OK");
JLabel lbl=new JLabel("Enter your name");
JTextField txtfield=new JTextField(20);
JCheckBox chkbox=new JCheckBox("Bold");
JRadioButton radiobtn=new JRadioButton("Red");
JList list=new JList();
JTextArea txtarea=new JTextArea();


public Name()
{

setLayout(new FlowLayout(FlowLayout.LEFT,0,0));

add(btn1);
add(lbl);
add(txtfield);
add(chkbox);
add(radiobtn);
add(list);
add(txtarea);

btn1.addActionListener(this);
//txtfield.addActionListener(this);



}

public void actionPerformed(ActionEvent e)
{
if(e.getSource == btn1)
{
String nameinput=txtfield.getText();
txtarea.setText(nameinput);
}



}

public static void main(String[] args)
{
Name obj=new Name();
obj.setTitle("LAB 3 Q2");
obj.setVisible(true);
obj.pack();
}
}

When posting code please wrap it in [code] tags [/code] so it retains its formatting.

getSource is a method, not an attribute of ActionEvent, so you need ().

[NajwaMy]

I'm so sorry I don't understand..

[jim829]

You're treating getSource as a field/attribute/variable, not a method. So you need closing ().

Is it like this?

[if(e.getSource() == btn1)]

[jim829]

Yep, but skip the square brackets.

I had done that but i got this error

Name1.java:35: error: method addActionListener in class AbstractButton cannot be
applied to given types;
btn1.addActionListener(this);
^
required: ActionListener
found: Name1
reason: actual argument Name1 cannot be converted to ActionListener by method
invocation conversion
1 error

[Tolls]

It's told you the problem.
addActionListener() requires an ActionListener as the parameter.
You haven't given it an ActionListener (ie Name1 does not implement ActionListener).

And if you do not understand what that means then you need to at least go through the Java Basics part of the tutorial linked in jim's signature above.
