graphic in java

Hi all :
we need to do some graphic projects using java , without using its classes .. the main topic about how to store color in memory by taking RGB values
so we should writes a java code to store color values and then draw it in screen ..
can any one help me ?

Welcome to CodeRanch!

What do you mean by "without using its classes"? Are there certain libraries you aren't allowed to use?

In such case you wanna write your own classes for those graphics as you wish and call the RGB values as per your requirement might this link will help you How to’s – Creating RGB color generator using Java

That link doesn’t help, I am afraid, because there is no public access to the code.

without using color class to set RGB values . we should build class to take these value and store it in computer memory . the basic about how colors are creation , then to show it and put color pixel in screen ..

That seems like an arbitrary restriction. It's also unworkable, as that class (and the Paint interface) is how RGB values are passed to most of AWT's and Swing's drawing routines. There's also little point in trying to avoid using it, as it would be used under the hood (within the AWT/Swing code) anyway. Can you tell us why it should be avoided? This seems like an implementation decision that should be up to the developer.

You mean write directly to graphics memory? Not possible in Java.

This my first task in my graphic course .. i don 't know .. i am also see it impossible .. but that it > thanks all

I think you need to go back and ask what it means about not using pre‑existing classes. You may have misunderstood that bit.
