Why is int used in while it is not a variable that stores characters in object creating

Question

My question is why when you are creating a class or object in java one uses int variable to describe the object while it doesn't store character variables.I have an example;private int wheels;

Answer 1

I don't understand your question, can you explain please?

int is for integer, it is a number
char is for character, it is a "letter"

Answer 2

Complete your example. 'private int wheels;' can be many things.
