How to draw a rectangle in Java using drawRectintintintint f

How to draw a rectangle in Java using drawRect(int,int,int,int) from its CENTER POINT, so that I can use drawRect() by saying drawRect(centerX,centerY,width,height)

Solution

For this, we\'ll create a Swing program,

public class RectanglesDrawingExample extends JFrame {
     public RectanglesDrawingExample() {

        super(\"Rectangles Drawing Demo\");

        getContentPane().setBackground(Color.WHITE);

        setSize(480, 200);

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        setLocationRelativeTo(null);

    }

void drawRectangles(Graphics g) {

        Graphics2D g2d = (Graphics2D) g;

public class RectanglesDrawingExample extends JFrame {
     public RectanglesDrawingExample() {

        super(\"Rectangles Drawing Demo\");

getContentPane().setBackground(Color.WHITE);

        setSize(480, 200);

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        setLocationRelativeTo(null);

    }

void drawRectangles(Graphics g) {

        Graphics2D g2d = (Graphics2D) g;
g2d.drawRect(30, 50, 420, 120);

}

public static void main(String[] args) throws Exception {

SwingUtilities.invokeLater(new Runnable() {

            @Override

            public void run() {

                new RectanglesDrawingExample().setVisible(true);

            }

        });

    }

}
