Why can't I set my layout to GridBagLayout anymore?

Question

I'm getting an error when I set my layout to GridBagLayout but it worked just fine before.

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

public class GridBagLayoutTest {
public static void main (String [] args)
{
    JFrame frame = new JFrame();
    frame.setLayout(new GridBagLayout()); 
}

}

I'm getting an error saying:

Exception in thread "main" java.lang.Error: Unresolved compilation problem: The method setLayout(LayoutManager) in the type JFrame is not applicable for the arguments (GridBagLayout)

Answer 1

You have to import java.awt package since GridBagLayout class belongs to that package.
