Java Tutorial Our core Java programming tutorial is designed for students and working professionals. Java is an  object-oriented , class-based, concurrent, secured and general-purpose computer-programming language. It is a widely used robust technology. What is Java Java is a  programming language  and a  platform . Java is a high level, robust, object-oriented and secure programming language. Platform : Any hardware or software environment in which a program runs, is known as a platform. Since Java has a runtime environment (JRE) and API, it is called a platform. Java Example Let's have a quick look at Java programming example. A detailed description of hello Java example is available in next page. class  Simple{        public   static   void  main(String args[]){        System.out.println( "Hello Java" );       }   }   Test it Now Application According to Sun, 3 billion devices run Java. There are many devices where Java is current

UML is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems. UML was created by the Object Management Group (OMG) and UML 1.0 specification draft was proposed to the OMG in January 1997. OMG is continuously making efforts to create a truly industry standard. UML stands for  Unified Modeling Language . UML is different from the other common programming languages such as C++, Java, COBOL, etc. UML is a pictorial language used to make software blueprints. UML can be described as a general purpose visual modeling language to visualize, specify, construct, and document software system. Although UML is generally used to model software systems, it is not limited within this boundary. It is also used to model non-software systems as well. For example, the process flow in a manufacturing unit, etc. UML is not a programming language but tools can be used to generate code in various languages using UML diagrams.

Python  is a general-purpose interpreted, interactive, object-oriented, and high-level programming language. It was created by Guido van Rossum during 1985- 1990. Like Perl, Python source code is also available under the GNU General Public License (GPL). This  tutorial  gives enough understanding on  Python programming  language. Why to Learn Python? Python  is a high-level, interpreted, interactive and object-oriented scripting language. Python is designed to be highly readable. It uses English keywords frequently where as other languages use punctuation, and it has fewer syntactical constructions than other languages. Python  is a MUST for students and working professionals to become a great Software Engineer specially when they are working in Web Development Domain. I will list down some of the key advantages of learning Python: Python is Interpreted  − Python is processed at runtime by the interpreter. You do not need to compile your program before executing it. This is
