Answer / gyana
In java by using class we cannot use concept of multiple
inheritance.but by using interface we can apply multiple
inheritance.
Class is a userdefined type declaration.Interface is a set
of rules that all d classes and interface who use it should
be obey the rule.
Normal class:-
class abc
{
public void a()
{}
}
interface declaration
Interface Iabc
{
public void ok()
{
}
}
class using interface
class abc:Iabc
{
public void ok()
{
string a="ABC";
return a;
}
}
