Interfaces are same as classes but their methods are
declared with out any body..... and definition
corresponding to that allmethods will write on
implementation class(i.e)single class.BUT
Eg:
interface interfacename
{
//Declarations only
//first method
//second method
..
..
//n-th method
//final variables
}
class classname implements interfacename
{
//Definitions of ALL methods present in interfacename
}
Abstract class also has same as interface and definitions of
all those methods may not be present in single extended class.

And we doesn't create an object to class that is abstract.

Can we override main method?

assume the program must insert 4 elements from the key board and then do the following programs.sequential search(search one of the elements),using insertion sort(sort the element) and using selection sort(sort the element).
