Answer 1

just google...

java: pie chart



I like this one code I pasted the link for you. It is a simple class you can use for starting your project. If you know java at all, you can subclass this code.



I don't know at what level you want. Swing will do this. Manning Publications "Swing" (first edition) has examples and the book is available online as a MS Word doc (free).



If you assignment is covering the Java2D graphics, the Sun Java2D has tutorials drawing charts.

Answer 2

It is apparent that your object will take in at least two attributes:

1) Should it be a pie or bar chart?

2) What are the values to be shown (most likely passed as an array)?



From there, you can draw a set of rectangles based on the values or you can draw a series of filled arcs based on the values. It is very straight-forward. Nothing tricky.

Answer 3

That is going to be quite difficult. If you are still stuck with your project assignment may be you can contact a java expert live at website like http://askexpert.info/ .
