    Question Hi, Can Someone please confirm if what am trying to do with Graphics is possible...if it is, then how? Thanks

    Hello,
    Am trying to draw a square, but i want it to have more than one color (maybe the top half is blue and the bottom half is red)
    Currently i can only manage to do this by drawing two different squares very close to each other, so they look like one square.
    Can Someone please tell me how to draw one square, and it will have more than one color.
    If this cannot be achieved using Graphics, then please tell me how so i can go and learn.
    Thanks in Advance

    What graphics API are you using?

    If you are talking about the way you draw things with Swing then I think it is impossible. Just draw 2 rectangles next to each other.

    I am advanced beginner or begining itermediate...so i only understand APIs from android development.
    I am using the graphics class, here is my code

    import java.awt.Color;
    import java.awt.Graphics;
    import javax.swing.JFrame;
    import javax.swing.JLabel;
    import javax.swing.JPanel;
     
     
    public class Grab extends JPanel{
     
    public void paintComponent(Graphics g){
     
    	Graphics b = null;
     
    	super.paintComponent(g);
     
    	this.setBackground(Color.GREEN);
     
     
     
    	g.setColor(Color.BLUE);
    	g.fillRect(25, 25, 25, 25);
     
    	g.setColor(Color.RED);
    	g.fillRect(25,50, 25, 25);
     
    }
    }

    if it is not possible then i will continue using two square as you suggested, thanks

    Essential if you really think about it. one square is a bunch of many squares called pixels. but if you wanted you could have a loop that creates all the lines and half way through it changes color
    It is not enough to know programming, but to think like the program

    You can draw a shape pixel by pixel if you want, changing the color of each pixel as you go. Your goal as a programmer should be to do what needs to be done to achieve the desired result as simply as possible.

    Combining two differently colored rectangles to make a two-colored square is the simplest way to do what you've described, at least with the graphics packages provided with Java SE. There may be 3rd-party packages that give you more options, but I haven't seen one that does what you've described.

    Not sure why you need an alternative to drawing two rectangles, if that's the result you wish to achieve. This being said, have a look at the GradientPaint class
    GradientPaint (Java Platform SE 7 )
    If you set the x/y parameters to the appropriate value, you can achieve a multi-colored Shape with a hard or soft interface.
