Java Development Kit is the official growth equipment for the Java programming
language. Java Development Kit accommodates the software program and instruments that
you might want to compile, debug, and run applets and purposes written utilizing the Java programming language.
JDK has a group of programming instruments, together with javac, jar, and the
archiver, which packages associated class libraries right into a single JAR file. This
software additionally helps handle JAR information, javadoc – the documentation generator,
which routinely generates documentation from supply code feedback, jdb –
the debugger, jps – the method standing software, which shows course of
data for present Java processes, javap – the category file disassembler,
and different elements are additionally included.
Key Contents embrace:
- Development Tools
(In the bin/ subdirectory) Tools and utilities that may assist you to develop,
execute, debug, and doc applications written within the JavaTM programming
- Runtime Environment
(In the jre/ subdirectory) An implementation of the Java Runtime Environment
(JRE) to be used by the JDK. The JRE features a Java Virtual Machine (JVM),
class libraries, and different information that assist the execution of applications
written within the Java programming language.
- Additional Libraries
(In the lib/ subdirectory) Additional class libraries and assist information
required by the event instruments.
- Demo Applets and Applications
(In the demo/ subdirectory) Examples, with supply code, of programming for
the Javaplatform. These embrace examples that use Swing and different Java
Foundation Classes, and the Java Platform Debugger Architecture.
- Sample Code
(In the pattern subdirectory) Samples, with supply code, of programming for
sure Java API’s.
- C header Files (In the embrace/ subdirectory) Header information that assist native-code
programming utilizing the Java Native Interface, the JVM Tool Interface, and
different performance of the Java platform.
- Source Code
(In src.zip) Java programming language supply information for all courses that make
up the Java core API (that’s, sources information for the java.*, javax.* and a few
org.* packages, however not for com.solar.* packages). This supply code is offered
for informational functions solely, to assist builders be taught and use the Java
programming language. These information don’t embrace platform-specific
implementation code and can’t be used to rebuild the category libraries. To
extract these file, use any widespread zip utility. Or, you could use the Jar
utility within the JDK’s bin/ listing: jar xvf src.zip.
The JDK additionally comes with a whole Java Runtime Environment. This consists of a Java Virtual Machine and the entire class
libraries current within the manufacturing setting, in addition to further libraries, internationalization
libraries and the IDL libraries.
