Question

I am trying to find a better interface, or better method to draw stuff on Java, basic stuff like lines, strings and shapes, they all turn out very pixeled and old looking, id like to improve that.

the more it is related to an existing java package, the better.

Answer 1

Take a look at Java 2D. You can set the drawing to render at higher quality via the setRenderingHints function. (If you turn on anti-aliasing you won’t see such jagged lines on your draw items.)

From the linked article:

public void paint(Graphics g) {
    Graphics2D g2d = (Graphics2D) g;
    g2d.setRenderingHints(RenderingHints.KEY_ANTIALIASING,
                          RenderingHints.ANTIALIAS_ON);
    // draw shapes...
}
