Question
2D Graphics
You have learned 2D graphics from DrawPanel.java (see code below)
// DrawPanel.java
// Using drawLine to connect the corners of a panel.
import java.awt.Graphics;
import javax.swing.JPanel;
public class DrawPanel extends JPanel
{
// draws an X from the corners of the panel
public void paintComponent( Graphics g)
{
// call paintComponent to ensure the panel displays correctly
super.paintComponent( g );
int width = getWidth(); // total width
int height = getHeight(); // total height
// draw a line from the upper-left to the lower-right
g.drawLine(0, 0, width, height);
// draw a line from the lower-left to the upper-right
g.drawLine(0, height, width, 0);
} // end method paintComponent
} // end class DrawPanel
3. Write a Java program that does all of the following 3 actions.
a. draws a line from (20, 50) to (50, x) of length 50. Compute the value x first.
b. draws a rectangle with (20, 50) as the lower left corner, height 10 and width 100.
c. fills a rectangle with (20, 50) as the upper left corner and height 20 and width 50.
Use 3 different colors for the three parts. Show screen captures and code.
Note. Please put the answers of parts a, b, and c in one screen (instead of 3 screens) since
you are supposed to have just one Java program that does these three all.
