如何在 Java 中将 RGB 值添加到 setColor() 中？

Question

How can I add (red, green, blue) values to my Java? For example:

 setColor(255, 0, 0);

The context looks like this:

public void render() {
    BufferStrategy bs = getBufferStrategy();
    if (bs == null) {
        createBufferStrategy(3);
        return;
    }
    Graphics g = bs.getDrawGraphics();

    g.setColor(); // <-- This line
    g.fillRect(0, 0, getWidth(), getHeight());

    g.dispose();
    bs.show();
}

I want to give my rectangle a color using RGB values like (200, 200, 200) for example; that'll be like a gray.

Answer 1

You can get a Color instance with the simple code:

Color myWhite = new Color(255, 255, 255); // Color white

Then, you can set RGB color to your object with something like that:

g.setColor(myWhite);

Hope it helps you!

Answer 2

Or you can do:

setColor(new Color(r, g, b));

For example:

setColor(new Color(0, 0, 0)); //sets the color to Black

Answer 3

You can do it with Graphics.setColor

For example:

g.setColor(Color.getHSBColor(255, 79, 18));

Answer 4

public static final Color VERY_LIGHT_GRAY = new Color(238,238,238);

and in your paintcomponent you add g.setColor(VERY_LIGHT_GRAY);

OR simply, gc.setColor(new Color(238,238,238));

Answer 5

You can try this:

bj1.setBackground(new Color(0, 62, 83));
bj2.setForeground(new Color(0, 00, 83));
bj3.setColor(new Color(0, 34, 83));

Alternatively, you can also pass Color object as parameter:

Color c = new Color(Color.yellow);
obj4.setBackground(c);
