RadixSort 1.6 build: 9639 released: 2008-01-01 compiled with: Java 1.8.0_131 RadixSort, mimics a card sorter. Copyright: (c) 1996-2017 Canadian Mind Products. Java class library. Download from: http://mindprod.com/products2.html#RADIXSORT ---- Notes: You must install the Java JDK to use this program. See http://mindprod.com/jgloss/jgloss/jdk.html You are pretty much on your own how to use this material. This program requires a manual install! See below. I put out an avalanche of free software into the world, and submit PAD files to hundreds of distribution sites, but I rarely hear back from anyone. What's happening? Does it all just work fine? It is so complicated nobody can figure out how to use it and they give up on it? It is it useful? Since everyone has the source, do people just fix the programs to their liking themselves? Did you have trouble installing? Do I presume you know too much? I would be happy to hear from you about your experiences, positive or negative and your requests for improvements. A one-line email to roedy@mindprod.com would be great. ===> Free <=== Full source included. You may even include the source code, modified or unmodified in free/commercial open source/proprietary programs that you write and distribute. May be used freely for any purpose but military. For more details on this restriction, see http://mindprod.com/contact/nonmil.html If you include any Canadian Mind Products code in your own applications, your app too must be labelled non-military use only. http://mindprod.com/contact/nonmil.html All Java jars and source code are included. If you need the class files or Javadoc, you will have to build them yourself. To streamline the zip downloads, class files and Javadoc have been removed. ---- Prerequisites: This program runs under any OS that supports Java, (e.g.W2K/XP/W2003/Vista/W2008/W7-32/W7-64/W8-32/W8-64/Linux/LinuxARM/LinuxX86 /LinuxX64/Ubuntu/Solaris/SolarisSPARC/SolarisSPARC64/SolarisX86/SolarisX64/OSX/AIX...) so long as you have <><> Java version 1.8 <><> or later installed (32-bit or 64-bit Java). See http://mindprod.com/jgloss/installingjava.html for details. ---- Installing on a PC: Download source and compiled jar files to run on your own machine as a part of your own program. First install a recent Java JDK or JVM. See http://mindprod.com/jgloss/installingjava.html. To install, extract the zip download with WinZip (or similar unzip utility) into any directory you please, often J:\ -- ticking off the use folder names option. ---- Installing on a MacIntosh: Use Safari to download source and compiled jar files to run on your own machine as a part of your own program. Safari will automatically unpack the zip into ~/Downloads (version 10.5) [or on the Desktop (version 10.4 and earlier)]. First install a recent Java JDK or JVM. See http://mindprod.com/jgloss/installingjava.html. You may optionally move the download tree to a permanent home. I don't have a MacIntosh, just a PC, so I can't test my Java programs for Mac compatibility. In theory they should work without problems, but in practice that does not always happen. If you have problems please, let me know, preferably with screenshots and complete verbatim error messages. ---- Rebuilding: You are pretty much on your own how to use this material. ---- Use: RadixSort 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. May be freely distributed and and used for any purpose except military. You can test it with: java.exe -jar radixsort.jar The icon is a punch card. The radixsort algorithm works the same way a card sorter does, working right to left, column my column, dividing the "cards" into different pockets for each possible value. ---- Version History: 1.0 1996-01-01 initial version 1.1 1998-11-10 add name and address. 1.2 1998-12-28 use JDK 1.2 style Comparator interface. 1.3 2000-09-29 fix bug.
