How to scale size of interface without losing quality?

Question

Because I cannot see small letters I set windows display to 150%. All things on my monitor are resized without losing quality. But unfortunately, it doesn't happen with Java Swing interface. Indeed, the Swing interface is scaled, but it has a wrong quality.

Can somebody help me to solve it?

Depending on what exactly you mean by "quality", but you can set rendering hints with several options, eg anti-aliasing:

public void paint (graphics g){
    Graphics2D g2 = (Graphics2D)g;
    RenderingHints rh = new RenderingHints(
             RenderingHints.KEY_TEXT_ANTIALIASING,
             RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
    g2.setRenderingHints(rh);
...
}

There are several of these hints, you can find a list here .
