what is the main usage of an abstract keyword?please follow
the program
class A
{
void display()
{
System.out.println("hai");
}
void print()
{
}
}
class B extends A
{
void print()
{
System.out.println("Hello");
}
}
In this program i was gives the implementation of print()
according to my requirements in subclass.And there is no
definition in superclass then why we can use abstract
keyword before a method that i want to gives definition in
other classes,is any mistakes in the above usage of method?
