Question

How to compare?

class A
{

       B b;

       ArrayList aobj;
}

class B
{

      ArrayList bobj;
}

Now,

A Object1=new A();

A Object2=new A();

Object1 == Object2 ?

Answer 1

You would need to overload the == operator for Class A. The exact implementation depends on how you would want to define ==, but typically this would be a attribute by attribute comparison. So for you case check if the b members are equal and then check if the ArrayList are equal in length and have same elements.
