Base64 1.9 (Downloads: 303)
Java classes to encode/decode Base64 and Base64u Base64 is a freeware way of encoding 8-bit characters using
only ASCII printable characters similar to UUENCODE.
UUENCODE embeds a filename where BASE64 does not. You will
see BASE64 used in encoding digital certificates, in
encoding user:password string in an Authorization: header
for HTTP. The spec is described in RFC 2045.
Don't confuse Base64 with x-www-form-urlencoded which
is handled by java.net.URLEncoder.encod...

Sound 1.4 (Downloads: 250)
Create/synthesize sounds mathematically in Java. Sound lets you mathematically create sounds in Java.

then convert that to (or from) *.AU mu-law 8-bit encoding
format which you can then play with
AudioPlayer.player.start(bis) in an application or with
Applet.getAudioClip in an Applet.
This is just a sample program. You would insert your own m...

Wavelength 1.3 (Downloads: 273)
Wavelength creates Color objects given the light wavelength or the frequency Wavelength creates Color objects given the wavelength or
the frequency of the light rather than the usual RGB or HSB.
instead of:
Color c = new Color(255, 0, 0);
use the frequency in nanometers, and gamma 0.0. .. 1.0.
(gamma is intensity/brightness.)
Color c = Wavelength.wvColor( 400.0f, 0.80f );
The visible range of the spectrum is 380..780 nanometers.
Smaller is bluer.
or using frequency in Terahe...

RadixSort 1.6 (Downloads: 224)
RadixSort is a fast internal sort written in Java that mimics a card sorter. RadixSort is a fast internal sort written in Java that
mimics a card sorter. Source provided. It is faster than
both HeapSort and QuickSort. It sorts using a comparision
routine you provide to compare two elements to be sorted
plus a method to extract individual bytes from the keys to
be sorted. The time to sort each item unlike most sorts,
does not increase with larger sorts. It depends rather on
the key length.
