custom Graphics2D class
I've made the following code but i'm having some problems with the parameters, can anyone help please!
This is what i have made of the class and main program so far:
Class:
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class Game
{
JFrame jf;
public void window(int x,int y)
{
jf = new JFrame();
jf.setSize (500, 235);
jf.setLocation(300,200);
jf.setForeground(Color.green);
jf.setTitle ("Roquefort's attempt - <(''<)");
jf.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
Container con = jf.getContentPane();
Color col = new Color (204,230,227);
con.setBackground(col);
jf.setVisible(true);
}
public void painter(Graphics g,int x,int y)
{
g.setColor(Color.red);
g.fillRect(x,y,50,50);
}
}
and the main program
public class UseGame
{
public static void main (String[]args)
{
Game g = new Game();
g.window(800, 600);
g.paint(50,100);
}
}
I would be deeply grateful!

okay thats kind of what i wanted, but i want to be able to make lots of shapes without making lots of code (i.e. a method) , and i want these shapes to be able to move, hence the parameters for the paint method.
# 3
and the keeping the original background would be good as well.

okay dude i'm going to be honest, that code is insane, but sadly it is out of my league, i'm only a Gr11 learner.
I have made a program that had an oval bouncing around a screen, but that was using a method in a supplied class (hsa) which doesn't work with JGrasp.
you had to instantiate a console and then you could use the methods it supplied:
Console c = new Console (something like this)
then you could do this:
c.fillOval(x,y,width,height);
this is more like what i am looking for.
sorry bud but thanks for trying, i should have been more specific
# 6
do you know how to make a painting method like c.fillRect(x,y,width,height) ?i mean the program that you made is kinda what i want to have as a final result but i just want to make it simpler.
# 7
do you know how to make a painting method like c.fillRect(x,y,width,height) ?Probably. What is c. Where do you want the method (which class) and where do you want to call it from?
# 8
I'm so sorry that I didn't reply sooner, I haven't been able to get onto the net until now. You raised the following questions:
Q.)What is c
A.)'c' is the constructor, like if i make a class called Window i can do this in the main method 'Window w = new Window();' and to call the methods in the class all i would have to do is 'w.methodName();'.
Q.)Where do you want the method (which class)
A.)Not sure. Maybe something like 'Shapes'. But that can always be changed.
Q.)where do you want to call it from?
A.)Not quite sure what you mean, umm whatever is best.
If you are willing to do this for me, and I know beggars can't be choosers, could you maybe add a method that allows me to change the colours of a shape?, and if it is drawn or filled?
# 9
>where do you want to call it from?i want to be able to call the methods in the class from a main program, separate to that of the class file. If that is what you mean. otherwise not quite sure what you on about.
