1.)javax.swing.Timer projectortimer;

timer = new javax.swingTimer(5, new MoveListener());

timer.start();

the timer ticks for a certain amount of time then fires an event.

2.) the factors that affect our perception of movement of a graphical object are rate of acceleration friction bounciness

3.) flickering is caused by the speed of the display medium when painting complex images that must appear to be moving rapidly.

4.)if the object is moving in a certain direction at a certain speed it will continue in that direction at the same speed unless something causes it to change directions.

1.)you can use the getIconWidth() and getIconHeight() to get the size of the picture and then have the program set the window to that size.

2.) Circle(int x, int y, double r, Color c)

double rt = awsome.nextDouble * r

void setRadius (rt)

3.) you can use the two classes MouseAdapter and Mouse MotionAdapter.

1. JOptionPane.showInputDialog(“Enter your name”,” “);

2.JOptionPane.showMessageDialog(“/n robert o’coin” +”/n 2 my adress lane”

3.the dialog box returns the number as a string and Integer.parseInt and double.parseDouble convert it into an int or a double.

4.if it set its prefferd size the information would not be get cut off.

g.setColor(Color.blue)

g.drawRect(45, 20, 100, 5)

g.drawLine(20, 20, 100, 100)

g.drawOval(100, 100, 50 , 50)

g.drawLine(0,0,100,100)

g.drawLine(100,100, 200, 200)

g.drawLine(200,200,0,0)

g.SetColor(Color.blue)

g.drawRect(45, 20, 100, 5)

g.setColor(Color.red)

use the getheight and getwidth methods

4.color style size

1)The stopping state keeps the recursive from being circular.

2)two parts of any recursive method are some function in terma of f(n-1) and f(1) defined more specifically.

3) Recursion is more expensive than iteration because a method call ties up memory until it is complete.

4) provides a clear short solution

5) base * Raise which is base rased to expo -1

6) The method checks the value of int n then if n is 0 it returns the number 1, but if n is not zero it returns n

	exercise 8.9 robertocoin — Wed, 23 Jan 2008 18:32:08 +0000 1. 2. replace the JFrame with Japplet and replace the classes constructor with method init 3. applets can not read files off of the users computer. Exercise 7.2 robertocoin — Wed, 16 Jan 2008 14:09:52 +0000 1. A query controlled loop uses two classes. One class handles the ui and anther that deals with the function of the program. It defines the variable of the condition initally as true. Then after going through the program it resets the value of the variable to what the user inputs and will either continue running or not based on whether it makes the conditional true or false. 2.
