• Simple –

• Distributed
• Multithreaded
• Interpretive
• High performance

Simple:-

• Java technology has eliminated all the difficult and confusion oriented concepts like pointers, multiple inheritance in the java language.

• Java uses c,cpp syntaxes mainly hence who knows C,CPP for that java is simple language.

Object oriented:-

• Java is object oriented technology because it is representing total data of the class in the form of object.

• The languages which are support object,class,Inheritance,Polymorphism, Encapsulation,Abstraction those languages are called Object oriented.

Plateform independent:-

When we compile the application by using one operating system (windows) that Compiled file can execute only on the same operating system(windows) this behavior is called platform dependency.

Example :- C,CPP …etc

When we compile the application by using one operating system (windows) that Compiled file can execute in all operating systems(Windows,Linux,Mac…etc) this behavior is called platform independency.

Example :- java,Ruby,Scala,PHP …etc

Architectural Neutal:-Java tech applications compiled in one Architecture/hardware (RAM, Hard Disk) and that Compiled program runs on any architecture (hardware) is called Architectural Neutral.

Portable:-In Java the applications are compiled and executed in any OS (operating system) and any Architecture (hardware) hence we can say java is a portable language.

Robust:-

Any technology good at two main areas that technology is robust technology.

• Exception Handling
• Memory Allocation

Java is providing predefined support to handle the exceptions.

Java provides Garbage collector to support memory management.

Secure:-

• To provide implicit security Java provides one component inside JVM called Security Manager.

• To provide explicit security for the Java applications we are having very good predefined library in the form of java.security package.

Dynamic:-Java is dynamic technology it follows dynamic memory allocation (at runtime the memory is allocated).

Distributed:-By using java it is possible to develop distributed applications & to develop distributed applications java uses RMI,EJB…etc

Multithreaded:-

• Thread is a light weight process and a small task in large program.

1. In java it is possible to create user thread & it possible to execute simultaneously is called multithreading.

• The main advantage of multithreading is it shares the same memory & threads are important at multimedia, gaming, web application.

High Performance:-

If any technology having features like Robust, Security, Platform Independent, Dynamic and

so on then that technology is high performance.
