Java is simple such as it does not have any pointers‚ it has automatic memory allocation and garbage collector‚ and it has multiple inheritance with interfaces. Java is a platform-independent. Every Java source code is compiled to Java bytecode‚ which can be executed on any platform that has its own JVM without compilation. Modifiers – certain reserved words that specify the properties of the data‚ methods‚ and classes and how they can be used. Statements – a statement represents an action or a

The construction of Object-Oriented Database Management Systems started in the middle 80 ’s‚ at a prototype building level‚ and at the beginning of the 90 ’s the first commercial systems appeared. The interest for the development of such systems stems from the need to cover the modeling deficiencies of their predecessors‚ that is the relational database management systems. They were intended to be used by applications that have to handle big and complex data such as Computer Aided Engineering‚ Computer

The Difference Between Art and Design. The subject of what separates art and design is convoluted and has been debated for a long time. Artists and designers both create visual compositions using a shared knowledge base‚ but their reasons for doing so are entirely different. Some designers consider themselves artists‚ but few artists consider themselves designers. So what exactly is the difference between art and design? In this post‚ we’ll examine and compare some of the core principles of each

Compiler: A Definition Compiler‚ in computer science‚ computer program that translates source code‚ instructions in a program written by a software engineer‚ into object code‚ those same instructions written in a language the computer ’s central processing unit (CPU) can read and interpret. Software engineers write source code using high level programming languages that people can understand. Computers cannot directly execute source code‚ but need a compiler to translate these instructions into

Object-Oriented Design In the object-oriented design for the CD and DVD medial collection system we need to identify the information about the media we are making a system. In the CD and DVD media system we need the name or normally called title of the CD/DVD‚ its track length‚ genre information and the ratings of the CD/DVD. Other than this some general information also needed to make system working efficiently. Item CD DVD In this media collection we needs an Item class which keeps
