Below are the possible reason for error.
1. Check have you opened the compilation unit without having any GUI, like empty class or data bean
2. Have you included all the required libraries
3. verify the class path of the Project, if there is any typo, then also you'll get this issue.
4. Check whether the toolkit that you've installed was compatible with your windows version
5. Try click the "Show UI toolkits" to get the new toolkit, make sure it was correct.
When I got the same issue, I've used the following code to fix it. It was web reference. After confirming all the above steps, try use the following code.
public class X{ // Use your own class name
public static void main(String[] args) { // It is for main
JFrame f = new JFrame("A JFrame"); // regarding the frame
f.setSize(250, 250); // setting the size
f.setLocation(300,200); // Location
f.getContentPane().add(BorderLayout.CENTER, new JTextArea(10, 40)); // content pane detail
f.setVisible(true); // setting the visiblity
}
}
