Amanuensis to show you how to write Java I/O code.

signed Java Applet (that can also be run as an application).

----

Notes:

You must install the Java JRE to use this program.
See http://mindprod.com/jgloss/jgloss/jre.html

This hybrid program is mainly designed to be used as an Applet in a
browser but is can also be used from the command prompt, e.g. under
Windows command.exe or JPSoft tcc.exe, formerly called the DOS box. Just
clicking the programs in a directory listing will not do anything useful.
Just typing the program names at the command prompt will not either.

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 an application or Applet
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 <span class="click">use folder names</span> option.
To run as an application, type:
java.exe %JAVA_OPTIONS -ea -jar J:\com\mindprod\fileio\fileio.jar {put any parms here}

adjusting as necessary to account for where the jar file is.

----

Installing on a MacIntosh:

Use Safari to download source and compiled jar files to run on your own machine as an application or Applet.
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.
To run as an application, without parameters, just double click the jar file.

To run as an application with parameters, in bash shell type:
open Terminal.app
cd ~/Desktop
java.exe -ea -jar com/mindprod/fileio/fileio.jar {put any parms here}

adjusting as necessary to account for where the jar file is.

----

Rebuilding:

The zip already contains the necessary jar files, so unless you modify
the program, there is no need to recompile the source or rebuild the jar.
Configure.java basedir="E:/" in rebuild.xml to the drive where your files are.
Configure.java your certificate name with environment SET cert=mindprodcert2017rsa
Configure.java your certificate password with environment SET jarsignerpassword=sesame
Use ANT and rebuild.xml, not build.xml, to recompile and recreate the jar.

Use:

File I/O is a teaching tool that generates sample Java source code to read
or write the console, a sequential file, a random access file, a String,
an array of characters, an array of bytes, URL, HTTP CGI GET/POST, Socket
or Pipe.
It shows you how to read or write ASCII-8 bit characters (plain or
locale-encoded), Unicode 16-bit characters, raw bytes, big endian binary,
little endian binary, or serialised objects, buffered, unbuffered or gzip
compressed.
FileIO runs either as an application or as an applet that needs to run in
JDK 1.7+ capable browser. Source code and sample HTML included. May be
freely distributed and used for any purpose except military.
It works by asking you 4 multiple choice questions about what you want to
do. You fill in your choices in a dialog box at it instantly generates
the corresponding code that you can copy/paste and modify.
1) What is the type of the source/target?
- sequential file
- random access file
- String (in RAM i/o)
- char[] (in RAM i/o)
- byte[] (in RAM i/o)
- URL (remote i/o)
- HTTP CGI
- socket
- pipe
2) Do you want to read or write?
3) Which do you want: unbuffered, buffered or
compressed?
4) What is the format of the data being read or
written?
- raw, untranslated, bulk, 8-bit bytes
- default-encoded chars (usually 8-bit)
- locale-encoded chars (usually 8-bit),
e.g. IBM-OEM Cp437
- Unicode 16-bit chars
- big-endian binary (Java standard)
- little-endian binary (Intel standard)
- serialised objects
It generates 617 possible different example programs. This Applet does
not yet give you any help with the Java 1.4 javax.imageio.ImageIO class or
the java.nio classes: Buffer, ByteBuffer, ByteOrder, CharBuffer,
DoubleBuffer, FloatBuffer, IntBuffer, LongBuffer, MappedByteBuffer or
ShortBuffer.
You can run it online at mindprod.com/applet/fileio.html without
installing it.
