Presenting Java: Beta Source

This page explains how I converted the example source code used in the book to the Java (tm)

pre-beta release.

I downloaded the beta release:

      $ ftp www.dnx.com
      220 kind FTP server (UNIX(r) System V Release 4.0) ready.
      Name (www.dnx.com:decemj): anonymous
      331 Guest login ok, send ident as password.
      Password: my-email-address
      230 Guest login ok, access restrictions apply.
      ftp> cd pub
      250 CWD command successful.
      ftp> bin
      200 Type set to I.
      ftp> mget JDK*
      mget JDK-prebeta1-solaris2-sparc.tar.Z? yes
      200 PORT command successful.
      150 Binary data connection for JDK-prebeta1-solaris2-sparc.tar.Z (128.213.2.56,34827) (4284889 bytes).
      ftp> quit
      $

I uncompressed and unpacked the file:

      $ uncompress *.Z
      $ tar -xvf *.tar
      $ rm *.tar

The upgrade program is in java/bin/upgrade.

I made a script called update-java:

      for i in $* 
      do
              upgrade < $i > beta/$i
      done

I ran this upgrade script in the directory with my alpha source code:
```
      $ mkdir beta
      $ upgrade-java *.java
      
```
There were no errors in the conversion. :)
Then I made a script called show-diff:
```
      for i in $* 
      do
              diff $i beta/$i > $i.diff
      done
      
```
And I ran this and looked at the results to see the changes in the files:
```
      $ show-diff *.java
      $ more *.diff
      
```
I updated the @version date lines so that they reflect when I made this beta update.
I'm still working on the recompilation of all the code.
