Question

In case of Java when we write something like

Integer i = new Integer(20);

In the above case the obj is allocated on the heap

and in case of C#

Int32 i = new Int32();
i=10;

In this case the object is allocated on the stack

Are these just the difference in implementation wise or there are more differences too?

Correction: changed Integer to Int32 for C#

Answer 1

There is no Integer in C#, its either int or int32 and both are same. With respect to C# saying “Value types go to stack” is some what not correct. You need to see this article from Eric Lippert:
The Truth About Value Types

Edit: based on comment:

Int32 and int are same, the two are synonymous.
