  Java is an object oriented programming language which is laid on basic OOP Concepts. Abstraction, Encapsulation, Inheritance, Polymorphism, Object and Class. Abstraction is using basic components to represent something complex. As an example we know how to turn on the TV, but we don’t know the inside mechanism. However it does not affect to enjoy it. Basically in Java, abstraction is the representation of complex code and data using simple components like variables ,  classes, and objects. In simple way abstraction is the representation of the big picture by hiding the inner workings. Abstraction helps to create reusable, useful tools. It means that can create several different types variables, functions, or data structures as well as different  classes  of objects. Suppose if a class of variable is an address, this class will specify each address object shall have a name, street, city, and zip code and the objects are employee addresses, customer addresses, or supplier addres

With the rapid development of the technology, the most trending technology among the people is embedded system technology. An Embedded system is a computer based system with pre-defined function within a huge mechanical or electrical system, mostly with real time computing constraints. It is embedded as a part of a complete device including mechanical and hardware parts. Today many devices in use are controlled by embedded systems. Operations which are done behind the main flow are managed by the micro-controllers. Simply an Embedded system found in a well-developed technological  car and also in a usual oven in the kitchen. It means embedded systems are common in advanced devices as well as in simple devices. So called embedded systems are enriched with a hardware component, application software and a Real Time operating system. Real Time operating system is used to supervise the application software. An embedded system is a single functioned system. It is specialized to perfo
