![]() ![]() The concatenation is achieved by sequentially subscribing to the first source then waiting for it to complete before subscribing to the next, and so on until the last source completes. This happens because the split () function of the String class accepts a regular expression as an argument: (Arrays.toString('.split'.split('. The concat method executes a concatenation of the inputs, forwarding elements emitted by the sources downstream.
