Java spanned both sides of the client/server connection. Just an Appletsĭynamically extend the functionality of a Web browser Servlets dynamically extend the functionality of a Web server. A servlet is a small program that executes on the server. That Java would also be useful on server side. Not long after the initial release of Java, it became evident Servlets: Java on the Server SideĪs useful as the applets can be, they are just one half of client/server equation.

The main key, allows Java to solve, security and portability, both the problems, just described is that the output of Java compiler is notĮxecutable code, instead, it is bytecode, which is highly optimized set of instructions that is designed to be executed on the Java runtime system,Ĭalled as Java Virtual Machine (JVM). If any Java program were to be run on virtually any computer connected to Internet, there needed to be some way to enable that program toĮxecute on different system. Portability is a major aspect of Internet because there are many dissimilar types of computers and operating systems, connected to it. Java achieved this protection by confining (limiting) an applet to the Java execution environment and not allowing it access to the other parts of the computer.

At the core of the problem is fact that the malicious code can cause itsĭamage because it has gained unauthorized access to system resources.

Java AppletsĪn applet is a special form of Java program that is designed to be transmitted over the Internet and automatically executed by aĪs you are probably aware, every time you download a 'normal' program, you are taking a risk (danger), because(as) the code you are going toĭownload might contain a virus. Java also addressed some of the thorniest issues associated with the Internet: portability and security. Simplifying web programming, Java innovated a new type of networked program called the applet that changed the way that the online world The Internet helped launcher Java to the head of programming, and Java, in turn, had a profound effect on the Internet.

To implement improvements and refinements in the art of programming.

To adapt to changing the environments and uses.

Like successful computer languages that came before, Java is a blend of the best elements of its deep heritage combined with innovative concepts,Īlthough Java has become inseparably linked with online environment of the Internet.Ĭomputer language and developments occurs for two fundamental reasons : To fully understand Java, one must understand the reason behind its creation, the forces that shaped it, and the legacy that it inherits. Java is developed in 1991 by sun microsystems. Java's ability to accommodate the fast rate of change in the computing world is a crucial part of why it has been and continues to Most importantly, it has not just followed the trends, it has helpedĬreate them. Since its original 1.0 release, Java has continually adapted to changes in the programming environmentĪnd to changes in the way that programmers program. Why Java?Ī key reason for Java's success is its agility. The bytecode interpreter is not dependent on any specific computer. This program is also called the Java Virtual Machine (JVM). The byte code interpreter program is used to run the Java program. General purpose language, like C and C++, any kind of problem can be solved in this language. Java is very similar to C++ but it is specially used for web page designing.

Java is a powerful object-oriented programming language. Today, Java is still the first and best choice in developing web-based applications. Unlike some other computer programming languages whose influence (shape) has waned (declined) with the passage of time, Java's has grown stronger.

Java is one of the world's most important, widely used computer programming language.
