Answer 1

You need to place your code in a code block such as a method or constructor rather than the class block of an inner class

/**
 * TODO: Refactor later NOT to extend from JFrame
 */
class MyFrame extends JFrame {

    void initComponents() {
        GridLayout setLayout = new GridLayout(10, 10);

        for (int i = 0; i < 10; i++) {
          ...
        }
    }
    ...
}
