Here is another type with only default constructors:
# see the code in Chapter 6\inner_constructors.jlmutable struct Person firstname::String lastname::String sex::Char age::Float64 children::Array{String, 1}endp1 = Person("Alan", "Bates", 'M', 45.5, ["Jeff", "Stephan"])
This example demonstrates that an object can contain collections, such as arrays or dictionaries. Custom types can also be stored in a collection, just like built-in types, for example:
people = Person[]
This returns 0-element Array{Person,1}:
push!(people, p1)push!(people, Person("Julia", "Smith", 'F', 27, ["Viral"]))
The show(people) function now returns the following output:
Person[Person("Alan", "Bates", 'M', 45.5, ["Jeff", ...
