I am trying to user Swing in Eclipse but I keep getting this error. See below

Question

private void initialize() {
        frame = new JFrame();
        frame.setBounds(100, 100, 450, 300);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        JLabel lblSomeText = new JLabel("Hello, World!");
        frame.getContentPane().add(lblSomeText, BorderLayout.CENTER); //error here

    }

It says: "The Type container is not visible around the frame.getContentPane()"

The following complete code works for me. Please check your imports and show us your entire code so we can help you!

package stackoverflow;

import javax.swing.JFrame;
import javax.swing.JLabel;

public class SwingTest {

   public static void main( String[] args ) {
      JFrame frame = new JFrame();

      JLabel lblSomeText = new JLabel( "Hello, World!" );
      frame.getContentPane().add( lblSomeText );

      frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
      frame.setSize( 640, 480 );  // use setSize() instead of setBounds
//      frame.pack();             // or call pack() instead
      frame.setLocationRelativeTo( null );
      frame.setVisible( true );
   }

}
