Why are there so many data types in a programming language?
Especially byte or short, because they are completely replaced by int. What are they needed for? What is their profit?

Good afternoon!

Why are there so many data types in a programming language?
Especially byte or short, because they are completely replaced by int. What are they needed for? What is their profit?

The data type int takes 4 bytes, while byte takes 1 byte and short takes 2 bytes.
Accordingly, in conditions of limited memory, only the appropriate types of primitives should be used.

Mainly size in memory. Well, on the network, data is transmitted precisely by bytes, so that they would not be repackaged and not given once again and they are used.
