JAVA PROGRAMMING
Step by Step need to know the Concept's.
OOP concepts- Data abstraction- encapsulation inheritance- benefits of inheritance- polymorphism-classes and objects- procedural and object oriented programming paradigm.
• Java programming – History of java- comments data types variables-constants-scope and life time of variables operators-operator hierarchy-expressions-type conversion and casting- enumerated types- control flow – block scope conditional statements-loops-break and continue statements- simple java stand alone programs-arrays console input and output- formatting output-constructors methods-parameter passing- static fields and methods access control- this reference- overloading methods and constructors-recursion-garbage collection- building strings exploring string class .
Need for OOP Paradigm
OOP is an approach to program organization and development, which attempts to eliminate some of the drawbacks of conventional programming methods by incorporating the best of structured programming features with several new concepts.
⮚ OOP allows us to decompose a problem into number of entities called objects and then build data and methods (functions) around these entities.
⮚ The data of an object can be accessed only by the methods associated with the object.
