Characteristics Of Java

Simple

• Java is Easy to write and more readable. 

• Java has a concise, cohesive set of features that makes it easy to learn and use. 

• Most of the concepts are drawn from C++, thus making Java learning simpler

Secure

• Java program cannot harm other system thus making it secure.

• Java provides a secure means of creating Internet applications.

• Java provides secure way to access web applications.

Portable

• Java programs can execute in any environment for which there is a Java run-time

• system.

• Java programs can run on any platform (Linux, Window, Mac)

• Java programs can be transferred over world wide web (e.g applets)

Object-oriented

• Java programming is object-oriented programming language.

• Like C++, java provides most of the object oriented features.

• Java is pure OOP Language. (while C++ is semi object oriented)

Robust

• Java encourages error-free programming by being strictly typed and performing runtime checks.

Multithreaded

• Java provides integrated support for multithreaded programming.

• Architecture-neutral :

• Java is not tied to a specific machine or operating system architecture.

• Java is machine independent.

Interpreted

• Java supports cross-platform code through the use of Java bytecode.

• Bytecode can be interpreted on any platform by JVM (Java Virtual Machine).

High performance

• Bytecodes are highly optimized.

• JVM can execute bytecodes much faster .

Distributed

• Java is designed with the distributed environment.

• Java can be transmitted over internet

Dynamic

•  Java programs carry substantial amounts of run-time type information with them that is used to verify and resolve accesses to objects at run time.
