Java Class Hierarchy
SyncJEdit (Java IDE)

  1. Sync JEdit 1.20 - the advanced Java IDE - released on April/18/2006 (refer to).
  2. Understanding Java Class Hierarchy is very easy now because of the online software.

Version 3.201, jump to download directly

Java Launcher is a powerful Java tool and an easy-to-use software, which contains nine features totally:

  • Six launching features accessed in windows explorer (see picture 1)
    1. Run java applications and applets by double-clicking class files in explorer
      as if they are normal windows executable files.
      at same time, the software can check class errors (such as package error) and monitor streams for java exceptions
    2. Display java source code in text format and class hierarchy in graphic format by right-clicking class files in explorer
      class files are not restricted to application and applet classes, they can be any.
    3. Examine contents of jar and zip files in details without extracting them by just one right-clicking in explorer
      source code of class files, java, html, xml and all text formatted files inside those compressed files are displayed by interfaces of the feature.
    4. Compile thousands of java files by just one right-clicking in explorer.
      a perfect option allows java files to be compiled as a whole, directory by directory and file by file.
    5. Execute thousands of applications and applets by just one right-clicking in explorer.
      it detects applications and applets from class files automatically and provides all options required.
    6. Debug thousands of applications and applets by just one right-clicking in explorer.
      it automatically provides signatures of fields, methods, classes and more for stop-in, watching and tracking with debugging process.
  • Two creating features (see picture 2)
    1. Create windows exe files
      the software compresses all class and other files (such as image files) into a single exe file.
      the exe file can be launched by double-click in windows explorer as if it is a normal windows executable file.
      user icon, arguments of java method main(), system and user classpaths can be added to the exe file.
      you can distribute the single exe file to your customers without other files.
    2. Create executable jar files
      the jar files are compressed from all class and related files and compatible with multiple platforms.
      you can launch java application by double-click the jar files if using windows.
  • And Java Help System (refer to Picture 3 and 4)
    1. The software automatically generates an advanced Help System for JDK (or) J2SE documentations without spending your any energy and time.
      JDK documentations can be downloaded from java sun, normally you should have them unzipped in your computer already.
      Java Help System contains 4 pages (Contents, Index, Search and Favorite) on left-side window, it can displays not only html files as other help system does, but also all text formatted files, class files, jar and zip files.
      Once you have the Java Help System installed, your programming speed and qualities will be accelerated because you will get all info you need faster and easier.

If your download is slow, you can read followings, which describe popular java technologies and software.

  • JRE and J2SE (JDK)
    • Versions
      Following main versions have been released so far
      1.1x, 1.20, 1.2.1, 1.2.2, 1.3.0, 1.3.1, 1.3.2, 1.3.3, 1.4.0, 1.4.1, 1.4.2, 1.4.3, 1.4.4, 1.5.0 (5.0)
    • Differences between JRE (runtime environment) and JDK/SDK (development kits)
      from version 1.2,J2SE can be installed in two directories: JRE and JDK, which are slightly different.
      1. exe files
        unique in JRE: javacpl.exe, jucheck.exe, jusched.exe (in top bin directory)
        unique in JDK: javac.exe, jdb.exe, jar.exe, appletviewer.exe, javadoc.exe, javah.exe, javap.exe, jarsigner.exe, htmlconverter.exe, serialver.exe, packager.exe, rmic.exe, jconsole.exe, jstart.exe and more.
        public in both: java.exe, javaw.exe, javaws.exe, keytool.exe, klist.exe, servertool.exe, policytool.exe, and tools.jar.
      2. jar files
        unique in JRE: charsets.jar, deploy.jar, javaws.jar, jce.jar, jsse.jar, plugin.jar, rt.jar (in top bin directory)
        unique in JDK: dt.jar, tools.jar, htmlconverter.jar, jconsole.jar.
    JDK contains a sub-directory (named JRE also) which has same contents as JRE.
    the most differences are unique jars in JDK, such as tools.jar, if we use them as classpaths, we have to ask users to install them also.this also affects to j2ee, j2me. be careful with the difference even it is very slight.
    Curently, most of operating systems support java, such as Windows (95, 98, 2000, XP, NT, Me), Macintosh, console, DOS, UNIX, linux, solaris, redhat, Mac, palm, Pocket PC, Microsystems, Workstations, and Workgroups 3.11.
  • Java IDEs (IDEAs, editors)
    which are very helpful for java programming, followings is main list of them we found on the internet:
    Eclipse, Netbeans, Borland JBuilder, Microsoft J++, IntelliJ, Sun one studio (Forte), JCreator, BlueJ, JEdit, Judo.
    we also provide a new java IDE: syncjedit, hope you enjoy it.
    Those IDEs involve a huge of techniques, such as JavaBean, Ant, Swing, jdt, pde, toolkits, xhtml, php, apache ware, servlet, mobile phone, tomcat, remote network, telnet, ejb, webapp, hprof, webservice, alert, ftp, webservice, midi, harddisk, hackman, jad, spec, webcam, webcast, desktop, struts, calendar, wireless, archived shortcut, docking toolbar, website, droplet, autoconf, jakarta, LAN, WAN, over-riding, (enabled, disabled) controls.
  • Plain java and/or related editors
    Their main purposes may not for java (such as text, XML, HTML, XHTML).
    NotePad, Dreamweaver XM, Hex Workshop, Abyss Web Server, Macromedia Contribute, TextPad, PageBreeze, AceHTML, Hackman Hex, HomeSite (5.5), Arachnophilia (5.2), Crimson (3.7), Antechinus JavaScript (4.0), Sferyx JSyndrome (1.0), Code Visual to Flowchart (3.0), JawaBeginner (1.6.2), Source Edit (4.0), Adobe GoLive CS, HotHTML 2001 (1.0.10), EditPlus (2.12), Namo WebEditor 6.0 Suite, Metamill (4.0), Mobiledit (1.95), PixMatrix (2.1),
  • Installation tools
    most of installation tools can help to handle setup of java programs for distributions, main tools are:
    Install4J, Launchanywhere, installanywhere, installshield, inno, Astrum InstallWizard.
  • Decompilers (disassemblers, parsers)
    Java classes can be decoded by many software, it means that classes are not safe for encryption and encoding of security issues (i.e. credit-card, checkOut, shopping cart).
    Normally decompilers are developed using c++ and do not require JVM.
    We comment: DJ Java, Cavaj java, KineticFusion, Jascii.
