The java doesn't mean anything to me That make me very happy.

@array.dup is the way to copy any object in ruby

Thank you daniel, but my functionality is not return as a array.
I need to copy a source array to a destination array.

Thank you in advance

def java_inspired_method_sans_idiomatic_ruby(destinati on_array)
destination_array.replace @my_array
end

I don't understand what your asking then. This is a fairly standard way to
copy an object.
@array = [1,2,3,4,5]

@new_array = @array.dup

Maybe before we go off guessing you can show a bit more of your code.
While there are methods to copy and insert into another array, maybe
there is a more efficient solution.

Cheers

I meant to include this

irb(main):007:0> a=(1..10).to_a
=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
irb(main):008:0> a[2,4]=%w{a b c}
=> ["a", "b", "c"]
irb(main):009:0> a
=> [1, 2, "a", "b", "c", 7, 8, 9, 10]
irb(main):010:0> a.concat %w{foo bar}
=> [1, 2, "a", "b", "c", 7, 8, 9, 10, "foo", "bar"]
irb(main):011:0> a
=> [1, 2, "a", "b", "c", 7, 8, 9, 10, "foo", "bar"]
irb(main):012:0>
