Julia: OOP or not

Question

I\'m working on Juno with Julia.

I don\'t know if Julia supports OOP or not.

For example, is there something like class or struct of c+

Answer 1

When in doubt, read the documentation...

https://docs.julialang.org/en/v1/manual/types/#Composite-Types-1

Long story short:

struct MyType
    a::Int64
    b::Float64
end

x = MyType(3, 4)

x.a

EDIT: Methods are defined outside the type definition, e.g.

function double(x::MyType)
    x.a *= 2
end

Methods do not live inside the type, as they would do in C++ or Python, for example. This allows one of the key features of Julia, multiple dispatch, to work also with user-defined types, which are on exactly the same level as system-defined types.
