使用二维数组的矩形对象

Question

If i have a two-dimensional array, is it possible to print out the result as a rectangle?

Here is what i have come up with;

int[][] anArrayRectangle = {{0,0},{-2,0},{1,-2},
                            {0,1},{2,1},{2,0}};

Each point represents one out of six points which together create a rectangle in the unit circle. The question is if it is possible to display the rectangle in lines, not exclusively using the print method. Perhaps in an applet?

All tips are welcome.

Maybe you could use drawPolygon

---

import java.awt.Graphics;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class Rectangle extends JPanel {

private int xPos[] = {100, 150, 200, 200, 150, 100};
private int yPos[] = {100, 100, 100, 150, 150, 150};

public void paint(Graphics g) {

    super.paint(g);

    int length = xPos.length;

    g.drawPolygon(xPos, yPos, length);

}

private static JFrame frame = null;

public static void main(String[] args) {

    frame = new JFrame("Graphics");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(400, 400);
    frame.setVisible(true);

    Rectangle obj = new Rectangle();

    frame.add(obj);

}

}
