AWT method not recognised

Question

Hi, I am trying to compile a simple program on centering a window using the get local graphics environment method but I received the error "getCenterPoint()" symbol not recognised. Can someone help please. The code is below
import javax.swing.JFrame;
import java.awt.Point;
import java.awt.GraphicsEnvironment;
public class TryWindow3
     // The window object
     static JFrame aWindow = new JFrame("This is the Window Title");
     public static void main(String[] args)
          Point center = GraphicsEnvironment.getLocalGraphicsEnvironment().getCenterPoint();
          int windowWidth = 400;
          int windowHeight = 150;
          // Set position and size
          aWindow.setBounds(center.x-windowWidth/2, center.y-windowHeight/2,
                            windowWidth, windowHeight);
          aWindow.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          aWindow.setVisible(true);           // Display the window
}Thanks.

'getCenterPoint()' method is added since j2se1.4. Check the JRE version in your machine.
