Primary Goals of Java Technology

It is an easy programmable language. It eliminates many pitfulls of other languages such as pointer arithmetic and memory management that affects the robustness of the code.
It is object oriented to help you visualise the program in real- life terms.
It Enables you to streamline the code.
An Interpreted enviroment results in following benefits:

• Speed of development
• Code portability

Its a way for program to run more than one thread of activity.

Its a means to change program dynamically during thier runtime life enabling them to download code modules.

Its a means of ensuring security by checking loaded code modules.

Java tecnology architechture uses the following features to fulfill above goals:

• JVM(Java Virtual Machine).
• Garbage collection.
• The JRE(Java Runtime Environment).
• JVM tool Interface.
