What are the features of Java?

It is a simple, small and familiar

Java is a simple small language. The syntax of java is just like the C++ language. So it is very easy to learn. But programming in java is easier than in C++ because

1. It does not use header files

2. It eliminates the use of pointers

3. It eliminates operator overloading and virtual base classes.

4. So Java is a simple object-oriented language. Since Java is a small language we can write software that can run on small computers.

 

Java is Object-oriented

Java is a pure object-oriented language. Everything in Java is an object. All programs and data reside inside objects and classes. Object models in Java are simple and easy to extend.

 

Distribution of Java

Java has strong networking facilities. So using Java we can create applications on networks. Using Java we can open and use applications on the Internet. This facility helps users from different places to work together on a single application.

 

Robust if Java

In many other languages, attention is not given to memory management or the exceptional behavior of a program in different situations. So most programs failed. But these issues are clearly dealt with in java using the techniques called garbage collection and exception handling.

 

Secure Java

Since java is used for programming on the internet, security becomes an important issue. Before a java code from the internet is interpreted, a security check is applied to it. This ensures that the java code does not contain any unwanted elements like a virus.

 

Platform independent

Java compiler generates an architecture-neutral or platform-independent code called bytecode. These codes can be run in any type of system.

 

Java as a Portable

Java compiler generates a code called bytecode and this code can be used by any machine. In java, the size of the primitive data types is machine-independent. So java is a portable language.

 

Compiled and interpreted

Generally, computer languages are either compiled or interpreted. But java combines both compiler and interpreter. So java is a two-stage system.

Java compiler generates a machine-independent code called bytecode. These codes are not machine codes. But the java interpreter generates machine code from bytecode that can be directly executed by the machine that is running the java program.

 

High performance of Java

Since the java interpreter uses bytecodes, the performance is high. The speed is also comparable to other languages like C, C++

 

Java as Multithreaded and interactive

Multithreaded means handling more than one job at a time. Java supports multithreading. Java also supports construction of interactive programs.

 

Java Dynamic and extensible

Java is a dynamic language. So it is capable of linking dynamically new classes, methods, and objects. Java also supports functions written in other languages such as C and C++. These functions are called native methods. During run time native methods can be linked dynamically.
