Java is a programming language that was originally launched by Sun Microsystems in 1995. The language is fast, dependable and secure. As of 2014, Java is present in almost all gadgets because there are numerous programs and websites that do not function unless Java is installed.
There are many characteristics that make Java a simple language. The reason for this is that Java is created by using the best features from languages like C and C++. Java is extremely simple to understand for any individual who possesses expertise in object-oriented programming ideas.
Java is distributed and the commonly used protocols such as HTTP and FTP are created in Java. Programmers are able to call functions on these protocols which enable them to connect to the files from virtually any remote machine on the Web, instead of writing codes on their local system.
Java is secure and never uses memory pointers. All applications in Java are run under the sand box. Security administrator establishes the accessibility alternatives of a class such as reading and writing a file to the local disk. Java utilizes the public key encryption process to enable the Java programs to transfer over the web in a protected and encrypted form. The bytecode Verifier examines the classes after they are loaded.
Java is an object-oriented language and things are treated as objects to which methods are employed. There are no standalone techniques, constants and variables in Java. Bytecodes are compiled from Java code which is interpreted by Java virtual appliances. This offers mobility to any machine for which a virtual machine has been created. The interpreter application reads the source code and also converts it into computations. The two methods of compilation and interpretation permit considerable security and enhanced code checking.
