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;
}
}
