Java is an open source language that is, by design, intended to be highly portable. Portability means that the language is compiled in a method that is different from most programming, and not built for specific machines, but designed to work equally well on different hardware configurations.

Typically, a Java program creates mini-applications referred to as Applets, separately downloaded to your system while a website page loads. They can add infinite functionality to a website designed to work within the Applets’ architecture.

Java is based on sophisticated programming language and is used most effectively by specially trained programmers.

Java is not to be confused with JavaScript a very popular object-based programming language developed to incorporate into HTML documents to make them more interactive. JavaScript is an easy to use language that can be incorporated into website design by anyone familiar with HTML scripting.

The java language derives much of its syntax from C and C++but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to byte code that can run on any Java Virtual Machine (JVM) regardless of computer architecture.

Java is a general-purpose, concurrent, class-based, object-oriented language that is specifically designed to have as few implementation dependencies as possible.

It is intended to let application developers write once, run anywhere. Java is currently one of the most popular programming languages in use, and is widely used from application software to web applications.

Using Java Reflection

Reflection is a attribute in the Java programming language. It allows an executing Java program to inspect or “introspect” ahead itself, and control internal properties of the program. Like that, it’s possible for a Java class to obtain the names of all its members and display them.

The ability to examine and manipulate a Java class from within itself may not sound like very much, but in C,C++,Pascal programming languages this feature simply doesn’t exist.

The original and suggestion implementation Java compilers, virtual machines, and class libraries were developed by Sun from 1995. As of May 2007, in compliance with the specifications of the Java Community Process, Sun relicensed most of its Java technologies under the GNU General Public License.
