Keep getting only 1 error

Question

Hello everyone,
I am new to Java. I have a program that should change the background color when a button is clicked.
I keep getting the same error no matter what I do.
The error is "cannot resolve symbol
symbol: variable e
String arg = e.getActionCommand();
The error is on the second string statement.
Here is the code:
import java.awt.*;
import java.awt.event.*;
public class Buttons extends Frame implements ActionListener,ItemListener
     public Buttons()
     //set the layout
     setLayout(new BorderLayout(20,5));
           //Add buttons and Choice
           Button north = new Button("Red");
           Button south = new Button("Yellow");
           Button east = new Button("Cyan");
           Button west = new Button("Magenta");
           Choice colors = new Choice();
     //Add buttons and Choice to the frame
     add(north, BorderLayout.NORTH);
     add(south, BorderLayout.SOUTH);
     add(east, BorderLayout.EAST);
     add(west, BorderLayout.WEST);
     add(colors, BorderLayout.CENTER);
     //populating the Choice component
     colors.add("Red");
     colors.add("Yellow");
     colors.add("Cyan");
     colors.add("Magenta");
     colors.add("White");
     //Add ActionListener to buttons and ItemListener to Choice component
     north.addActionListener(this);
     south.addActionListener(this);
     east.addActionListener(this);
     west.addActionListener(this);
     colors.addItemListener(this);
     //override the windowClosing event
     addWindowListener(
              new WindowAdapter()
              public void windowClosing(WindowEvent e)
              System.exit(0);
     }// End of Constructor method
        public static void main(String[] args)
      // set frame properties
     Buttons f = new Buttons();
           f.setTitle("Button Application");
           f.setBounds(200,200,300,300);
     f.setVisible(true);
     f.setBackground(Color.RED);
                     public void actionPerformed(ActionEvent e)
             String arg = e.getActionCommand();
             if (arg == "Red")
             setBackground(Color.RED);
             if (arg == "Yellow")
             setBackground(Color.YELLOW);
             if (arg == "Cyan")
             setBackground(Color.CYAN);
             if (arg == "Magenta")
             setBackground(Color.MAGENTA);
             if (arg == "White")
             setBackground(Color.WHITE);
     public void itemStateChanged(ItemEvent ie)
          String arg = e.getActionCommand();
          if (arg == "Red")
          setBackground(Color.RED);
          if (arg == "Yellow")
          setBackground(Color.YELLOW);
          if (arg == "Cyan")
          setBackground(Color.CYAN);
          if (arg == "Magenta")
          setBackground(Color.MAGENTA);
          if (arg == "White")
          setBackground(Color.WHITE);
}

Hello everyone,
I have updated my code. It compiles now. The buttons work properly, but when a color from the Choice arrow is selected it changes the background color to white and it never changes unless I click a button.
What am I doing wrong?

import java.awt.event.*;
public class Buttons extends Frame implements ActionListener,ItemListener
     public Buttons()
          //set the layout
          setLayout(new BorderLayout(20,5));

           Button south = new Button("Yellow");
           Button east = new Button("Cyan");

            String arg = e.getActionCommand();

           if (arg == "Magenta")
           setBackground(Color.MAGENTA);
           if (arg == "White")
           setBackground(Color.WHITE);
     public void itemStateChanged(ItemEvent ie)
          if (ie.getStateChange() == ItemEvent.SELECTED)
          setBackground(Color.RED);
          if (ie.getStateChange() == ItemEvent.SELECTED)
          setBackground(Color.YELLOW);
          if (ie.getStateChange() == ItemEvent.SELECTED)
          setBackground(Color.CYAN);
          if (ie.getStateChange() == ItemEvent.SELECTED)
          setBackground(Color.MAGENTA);
          if (ie.getStateChange() == ItemEvent.SELECTED)
          setBackground(Color.WHITE);
}Thanks for your assistance
