Question

The following program draws squares recursively. Fill in the missing code. import javax.swing\.\*; import java.awt\.\*; public class Test extends JApplet { public Test() { add(new SquarePanel()); } static class SquarePanel extends JPanel { public void paintComponent(Graphics g) { super.paintComponent(g); int width = (int)(Math.min(getWidth(), getHeight()) * 0.4); int centerx = getWidth() / 2; int centery = getHeight() / 2; displaySquares(g, width, centerx, centery); } private static void displaySquares(Graphics g, int width, int centerx, int centery) { if (width >= 20) { g.drawRect(centerx - width, centery - width, 2* width, 2 * width); displaySquares(________, width - 20, centerx, centery); } } } }

Answer 1

Answer:

The missing code to this question is g.

Explanation:

In this question firstly import packages. Then declaration of the class Test that inherits the JApplet. In this class, we declare the default constructor. In this constructor, we call the add function. Then we declare another class that is SquarePanel. This class inherits JPanel. In this class, we define a method that is paintComponent(). In this method, we define an integer variable. In this method, we perform calculations and pass it to another function that is displaySquares(). In this function, we pass the value as the arguments. So in question the missing code or argument is g.
