I was looking into this and just wondering does Java provide any construct to find out the size of an object?

I was looking into this and just wondering does Java provide any construct to find out the size of an object?
No. It goes against the concept of the language. In a real Object Oriented Programming language (not a hacked-together OOP support like C++), Objects are abstract concepts, not bits on the computer. Until and unless you serialize the object, it’s treated like an actual object and not a sequence of bits.
