Have your canvas implement the java.awt.event.MouseMotionListener interface and add itself as its own MouseMotionListener. Make your program draw small filled circles as the mouse is dragged. Congratulations: youve recreated the basics of MacPaint!

Extend your program to work as follows: When the mouse is first pressed, draw a small circle as above. As the mouse is dragged, draw a line connecting the original point to the current position of the mouse. Erase the previous line first so that your canvas doesnt get covered in black. When the mouse is released, leave the last line on the canvas. Think about what you need to keep track of between events to make this work. This needs to be part of the state of your canvas. . .

I need to do this in java. thank you!
