When creating big applications(even medium apps) there are so many different kinds of exceptions that can come?

How to go about handling them?

class A can implements I1 or I2 depending on how it is constructed

interface I1 {
 void A();
 void B();
}
 
interface I2 : I1 {
 void C();
 void D();

class A : I1 {
 // Implementations of the I1 functionality, and the I1 type constructor
 public virtual void A() {}
 public virtual void B() {}
}
 
class A2 : A, I2 {
 // Implementations of the I2 functionality, and the I2 type constructor

 public void D() {}
 
 // You can also override implementations from A
 public override void A() {
  base.A();
  // other stuff

Also we can make class A as abstract to make sure no one is able to create it directly as its only purpose is to facilitate default implementation for optional functions.
