can we create a instance for intwerface?..

Answer / subhash

No.We cannot create instance for interface.But we can
create reference to an interface.We can implement the
interface by creating sub class(implementation class) and
creat instance to the sub class, then you can create
reference to the interface by assigning instance of sub
class to the interface reference variable.

Answer / uma

no.Interface is similar to class but they lack instance
variable, their methods are declared with out any body.
Interfaces are designed to support dynamic method
resolution at run time. All methods in interface are
implicitly
abstract, even if the abstract modifier is omitted.
Interface methods have no implementation;

Answer / amit kumar gautam

Though it is correct that interfaces are basically used for
obtaining the dynamic resoulution of the Method and they
usually can not be instantiated but it is also possible to
instantiate the same in case of anonymous classes and it
works fine.......

class Amit
{

void addCode()
{
Runnable rr=new Runnable()
{
public void run()
{
System.out.print("This is Amit")
}
};
Thread tt=new Thread(rr);
tt.start();

}
}

class Check
{
static public void main(String[]amit)
{
new Amit().addCode();
}
}
