What is Java Programming?
What is Java?
Java Programming Language is one of the most important, widely used computer Programming Languages in the world. In contrast to some other computer programming languages whose size of impact has decreased with years gone by, Java has become stronger.
Today, Java Programming Language is the first and the best choice in developing web-based applications and Android development.
Why Java?
One of the main reasons for Java's success is its agility. Since its original 1.0 release, Java has continually optimized for changes in the programming environment and changes in the programmer program's way. Most importantly, it has not followed trends, it has helped in making them. Java's ability to adjust the fast rate of change in the computing world is an important part of why it has been successful and continues.
History of Java
In order to fully understand java programming language one must understand the reason behind its creation, inheriting its legacy powers and shapes to inherit it. As the first successful computer languages, Java is a mix of the best elements of deep heritage combined with the new concepts needed by its unique mission.
- Although Java is incredibly connected to the internet online environment.
- Computer language and development happen to two fundamental reasons:
- To customize the environment and change the usage
- To improve the art of programming and to implement abstraction.
Java applets
An applet is a special form of Java program that is designed to be sent to the Internet and is executed automatically by browsing the Java-compatible web.
Java in Security
As you probably know, every time you download the "normal" program, you are taking the risk (danger) because (as) the code you are about to download may contain a virus. Trojan Horse, or other harmful code. The root cause of the problem is that the malicious code can cause its harm because it has unauthorized access to system resources.
Java on the Server Side
Can be useful as an applet, they are only one half of the client/server equation. Shortly after the initial release of Java, it became clear that Java would also be useful in favor of the server. The result was the servlet. A servlet is a small program that is executed on the server. Just one apple spreads the functionality of a web browser dynamically; Servlets dynamically expand the functionality of a web server. Therefore, with the arrival of the servlet, the Java client/server spread on both sides of the connection.
