|
<div><p>The Java™ Development Kit (JDK) is software that is distributed
|
||
|
|
by Sun Microsystems, Inc. for Java developers. It includes the Java interpreter, Java classes,
|
||
|
|
and Java development
|
||
|
|
tools: compiler, debugger, disassembler, appletviewer, stub file generator,
|
||
|
|
and documentation generator.</p>
|
||
|
|
<p>The JDK enables you to write applications that are developed once and run
|
||
|
|
anywhere on any Java virtual machine. Java applications that are developed with
|
||
|
|
the JDK on one system can be used on another system without changing or recompiling
|
||
|
|
the code. The Java class files are portable to any standard Java virtual
|
||
|
|
machine.</p>
|
||
|
|
<p>To find more information about the current JDK, check the version of the IBM<sup>®</sup> Developer
|
||
|
|
Kit for Java on your iSeries™ server.</p>
|
||
|
|
<p>You can check the version of the default IBM Developer Kit for Java Java virtual
|
||
|
|
machine on your iSeries server
|
||
|
|
by entering either of the following commands:</p>
|
||
|
|
<ul><li><samp class="codeph">java -version</samp> on the Qshell command prompt.</li>
|
||
|
|
<li><samp class="codeph">RUNJVA CLASS(*VERSION)</samp> on the CL command line.</li>
|
||
|
|
</ul>
|
||
|
|
<p>Then, look for the same version of Sun Microsystems, Inc. JDK at <a href="http://www.java.sun.com/" target="_blank">The Source
|
||
|
|
for Java Technology
|
||
|
|
java.sun.com</a> for specific documentation. The IBM Developer Kit for Java is
|
||
|
|
a compatible implementation of the Sun Microsystems, Inc. Java Technology,
|
||
|
|
so you should be familiar with their JDK documentation.</p>

<div class="section"><h4 class="sectiontitle">Java packages</h4><p>A Java package is a way of grouping related
|

|
|
classes and interfaces in Java. Java packages are similar to class libraries
|

|
|
that are available in other languages.</p>
|
||
|
|
<p>The Java packages, which provide the Java APIs,
|

are available as part of Sun Microsystems, Inc. Java Development Kit (JDK). For a complete

<div><a href="jarfile.htm" title="A Java ARchive (JAR) file is a file format that combines many files into one. The Java environment differs from other programming environments in that the Java compiler does not generate machine code for a hardware-specific instruction set. Instead, the Java compiler converts Java source code into Java virtual machine instructions, which Java class files store. You can use JAR files to store class files. The class file does not target a specific hardware platform, but instead targets the Java virtual machine architecture.">Java JAR and class files</a></div>

Java is a multithreaded programming language, so more than one thread may be running within the Java virtual machine at one time. Java threads provide a way for a Java program to perform multiple tasks at the same time. A thread is essentially a flow of control in a program.">Java threads</a></div>
