Features of java

Introduction

The main reason for creating Java was to bring the functionality of portability and security to a computer language. In addition to these two main features, many other resources have played an important role in shaping the final form of this excellent language. These resources are:

1) Simple

Java is easy to learn and its syntax is simple, clear and easy to understand. The confusing and ambiguous concepts of C ++ are omitted in Java or have been more clearly implemented.

For example: operator pointers and overloading are not present in Java, but they were an important part of C ++.

2) Object-oriented

In Java, everything is an object that contains data and behavior. Java can be easily extended because it is based on the object model.

3) Robust

Java strives to eliminate error prone code by focusing primarily on validating compile errors and checking execution. But the key areas in which Java has improved include memory management and incorrect exception handling, automatic garbage collection, and exception handling.

4) Independent platform

Unlike other programming languages ​​such as C, C ++, etc., which are compiled in platform-specific machines. It guarantees that Java is a unique registration language that works everywhere.

During compilation, the Java program is compiled into the bytecode. This bytecode is platform independent and can run on any machine in addition to this bytecode format, which also provides security. Any Java Runtime Environment machine can run Java programs.

5) Secure

For security reasons, Java is always the first choice. With the secure resources of Java, we can develop a system without viruses and temperament. The Java program always runs in the Java runtime environment, with virtually no interaction with the operating system and therefore more secure.

6) Multi-threading

With the Java multithreading feature, you can write a program that can perform multiple tasks simultaneously. The benefit of multithreading is that it uses the same memory and other resources to execute multiple subprocesses at the same time, as grammatical errors are checked during writing.

7) Architecturally neutral

The compiler generates bytecodes that have nothing to do with a particular computer architecture; Therefore, it is easy to interpret a Java program on any machine.

8) Portable

Java byte code can be transported on any platform. No resources depending on the implementation. Everything about memory is predetermined, for example: size of primitive data types

9) High performance

Java is an interpreted language, so it will never be faster than a C or C ++ compiled language. But Java allows high performance with the use of the compiler just in time.

New features of JAVA 8Here are some of the key enhancements made in the Java 8 release: quickly search them and explore them in more detail later.

• Improved productivity, provision of optional class function, lambda expressions, flows, etc.

• Easy to handle

• Improved polyglot programming. A polyglot is a program or script that is written in several programming languages ​​in a valid format and performs the same operations in multiple programming languages. Therefore, Java now supports this type of programming technique.

• Improved safety and performance.
