17. What are the OOPS concepts? and What are the use of OOPs concept?

Answer:

1) Encapsulation: It is the mechanism that binds together code and data in manipulates, and keeps both safe from outside interference and misuse. In short it isolates a particular code and data from all other codes and data. A well-defined interface controls the access to that particular code and data.
2) Inheritance: It is the process by which one object acquires the properties of another object. This supports the hierarchical classification. Without the use of hierarchies, each object would need to define all its characteristics explicitly. However, by use of inheritance, an object need only define those qualities that make it unique within its class. It can inherit its general attributes from its parent. A new sub-class inherits all of the attributes of all of its ancestors.
3) Polymorphism: It is a feature that allows one interface to be used for general class of actions. The specific action is determined by the exact nature of the situation. In general polymorphism means "one interface, multiple methods"; this means that it is possible to design a generic interface to a group of related activities. This helps reduce complexity by allowing the same interface to be used to specify a general class of action. It is the compiler's job to select the specific action (that is, method) as it applies to each situation.

hi everyone,
Ya..television has impact on children,but in same television help the children to learn good thing and humanity.
Sometimes we have to think out of the box,nowadays there are many programmes which help the children in gaining academic and creative knowledge too, instead of getting used to of watching television we have limit the children a certain time for watching television...by doing this they wont be distracted from thier studies and also they will be updated and satisfied.
