Language Principles

 

There were five primary goals in the creation of the Java language:

• It should be “simple, object-oriented and familiar”
• It should be “robust and secure”
• It should be “architecture-neutral and portable”
• It should execute with “high performance”
• It should be “interpreted, threaded, and dynamic”

Java Editions

 

There are four editions of Java defined and supported, targeting different application environments. The APIs are segmented so that they belong to one of the platforms. The platforms are:

• Java Card for smart cards.
• Java Platform, Micro Edition (Java ME)  targeting environments with limited resources.
• Java Platform, Standard Edition (Java SE) targeting workstation environments.
• Java Platform, Enterprise Edition (Java EE) targeting large distributed enterprise or Internet environments.
