suppose we have two object;obj1 and obj2 can we assign obj2 to one1; and if yes; then after assign..

Answer / mahesh kotekar

Very tricky question, perhaps i would like to answer this
one with small coding.
Employee e1 = new Employee('mahesh','Software');
Employee e2 = e1;
e1 = null;

console.writeline(e2.FirstName);
Answer: We can assign the reference of the object to other
object. since both e1 and e2 refers to the same memory
location for the empllyee object. If we change the e1 then
refernce to memory of e1 will get deleted but e2 stil refers
to the same memory location Certainly it will work. and
retain the value.

Thanks And Regards
