well here's the thing im quite new here and i need ur help as im a noob at java yet a master at turing Smile

there is this program that requires me to output 4 filled colour squares at the absolute bottom of the java output page and each square must take a 1/4 of the page in order to fill the entire width of the page...

how would i go on attempting to do this..
oh also i have to use something like this void block ( int* xc, int* yc, howbig, Color.*clr)

* = not sure about
here's what i have yet


// The "Block" class.
import java.awt.*;
import hsa.Console;

public class Block
{
static Console c; // The output console

public static void main (String[] args)
{
c = new Console ();
int xc = c.getWidth () / 4; // Find the x corner
int yc = c.getWidth () / 4;
}


void block (xc, yc, howbig, Color clr);

drawRect (int x, int y, int howbig, Color.blue);
// Place your program here. 'c' is the output console
// main method
} // Block class


thx for ur help in advance

You might want to read the Java tutorial, because it seems like you do not know how to use methods.

"void block ( int* xc, int* yc, howbig, Color.*clr)"

I have no idea why the *s are there, they will just give you syntax errors AFAIK, just exclude them.

My friend just did something like this today. I suggested him the book "Head First Java". I used that book to start out java and it was a great help. Consider going to the library sometime...

You are not far enough along for anyone to help you without actually doing the work for you. It looks like you are struggling with the whole concept of a class and the role of constructors and methods. Try reading this: http://www.javacoffeebreak.com/java102/java102.html

Also, I'll second the recommendation for Head First Java. Great first Java book.

If it's not required for a class, I HIGHLY recommend avoiding use of the "Console" class, which is unique to a specific IDE (and not in Java itself). Use Swing and/or AWT for graphical output. You could make what you're suggesting pretty easily that way, and there are plenty of tutorials on Sun's website.

You mean Oracle's website, right? Laughing
