To begin developing Java programs, follow these steps:
Step 1: Obtain the Software
Development Kit (SDK) for J2SE (Java 2 Platform, Standard Edition),
which assumes typical desktop resources of memory, CPU speed, and
disk space:
- The SDK is available for free from Sun
MicroSystems for several common platforms. See the resources
page for alternate platforms and also for independent compilers
and JVMs from independent sources.
- The SDK contains the essentials needed to create and run Java
programs.
- The SDK includes
- Java executables -
javac (compiler), java
(interpreter), appletviewer,
etc.
- Class libraries
- Current (as of Oct.2004) release of Java 2 is version 5.0 (previously
1.5).
Step 2: Install the SDK
- The SDK now comes with an automatic installer for most common
platforms. Just run this program and follow its instructions.
- The installer should also place a plug-in into the browsers
that it finds on your system.
Step 3: Install Documentation
- We recommend that you have ready access to the Java
2 API Specification since the descriptions of the core language
classes will be very useful during program development. If you
do not have broadband continual Internet access, you may want
to download the documentation from Sun
and install it on your local drive.
