one error in Java code Please help?

Question

Hi Everyone

I need help with this code please. This code is created to import a adjustable graphic in an Applet. 
Code: import java.awt.*;
import java.awt.event.*;
import java.applet.*;

public class MoveIt extends Applet implements ActionListener
{
	// Declare Variables
	private Image cup;
	private Panel keyPad;
	public int top = 15;
	public int left = 15;
	private Button keysArray[];

	public void init()
	{
		cup = getImage(getDocumentBase(), "cup.gif");
		Canvas myCanvas = new Canvas();

		// Construct Panel and Buttons
		keypad = new Panel();

		keys[1] = new Button("Up");
		keys[2] = new Button("Left");
		keys[3] = new Button("Right");
		keys[4] = new Button("Down");
		keys[5] = new Button("Center");

		// Set Background Color
		setBackground(blue);

		// Set Layout Manager for Frame
		this.setLayout(new BorderLayout());

		// Set keypad Layout Manager
		this.setLayout(new BorderLayout());

		//Add Buttons to the keypad Panels
		keypad.add(Up, BorderLayout.NORTH);
		keypad.add(Down, BorderLayout.SOUTH);
		keypad.add(Left, BorderLayout. EAST);
		keypad.add(Right, BorderLayout.WEST);
		keypad.add(Center, BorderLayout.Center);
		add(myCanvas, BorderLayout.NORTH);
		add(keypad, BorderLayout.SOUTH);

		// Add ActionListener Statements for each of the Buttons
		UpButton.addActionListener(this);
		DownButton.addActionListener(this);
		LeftButton.addActionListener(this);
		RightButton.addActionListener(this);
		CenterButton.addActionListener(this);
	}

	public void paint(Graphics g)
	{
		g.drawImage(cup, left, top, this);
	}

	public void actionPerformed(ActionEvent e)
	{
		String arg = e.getActionCommand();

		if(arg == "Up")
			top = top -15;

		if(arg == "Down")
			top = top + 15;

		if(arg == "Left")
			top = top - 15;

		if(arg == "Right")
			top = top + 15;

		if(arg == "Center")
			top = 60;
			Left = 125;
	}

	repaint();
}

Error is: :&#92;Course Technology&#92;59850_Java3e_DF1-4&#92;Chapters 5-8&#92;Chapter06&#92;MoveIt.java:90: invalid method declaration; return type required
	repaint();

Try repaint during action performed.

public void actionPerformed(ActionEvent e)
{
String arg = e.getActionCommand();

if(arg == "Up")
top = top -15;

if(arg == "Down")
top = top + 15;

if(arg == "Left")
top = top - 15;

if(arg == "Right")
top = top + 15;

if(arg == "Center")
top = 60;
Left = 125;
repaint();
}
}
