Dear Sir, please upload missing videos as well. Ratan sir your videos are amazing and i cleared all my doubts. It is not good to stop important videos without uploading for Business purpose. Everybody know Durgasoft is no1 inst in Java. and 1000s of student in one class, there is no problem for money. But stop uploading imp videos makes bad impact on Durgasoft. Kindly upload as it is useful for many students worldwide whose not able to pay money.

it is not true that abstract class must have atleast one abstract method.

[himzsworld]

please explain ratan:-
abstract class Parent
{


abstract void m1();

abstract void m2();
abstract void m3();
void m4()
{
System.out.println("methpd m4 parent");

}


}
abstract class middle extends Parent
{
void m2()
{
System.out.println("methpd m2 in middle");

}
}

class Child extends middle

{
void m1()
{
System.out.println("methpd m1");

}
void m2()
{

System.out.println("methpd m2");

}

void m3()
{
System.out.println("methpd m3");

}

void m4()
{
System.out.println("methpd m4 child");

}



public static void main(String[] args)
{
Parent t1= new Child();
middle c=(middle)t1;
c.m2();
t1.m1();
t1.m2();
t1.m3();
t1.m4();
}
