Code:
public void setAlpha(int alpha, int width, int height) {

        if (alpha < 0)

                alpha = 0;

        else if (alpha > 100)

                alpha = 100;

        alpha *= 2.55;

        int w = width;

        int h = height;

        int[] pixels = new int[w * h];

        pixels = this.image.getRGB(0, 0, w, h, pixels, 0, w);

        for(int i = 0; i < pixels.length; i++)

                pixels[i] = ((pixels[i] == 0) ? 0 << 24 : alpha << 24) | (pixels[i] & 0xffffff);

        this.image.setRGB(0, 0, w, h, pixels, 0, w);

    }

Enjoy, rofl.

I'm kind of new to this, so do I have to insert anything else? Because when I used the w3school's Java Tryit Editor, it didn't show anything transparent, in fact a lot of the code is all that displayed.

All you do is invoke it. Of course, its meant for pictures and such.
