java - Adding ".foreach" capability to a custom container class -

i wrote own container class game, similar of arraylist different in quite few ways, anyhow want write foreach method iterate on backing array.

i know use arrays.stream i'm curious how write custom lambda implementation of #foreach method iteration on array.

anybody have clue? thanks

example:

class container<t> {     t[] array = new t[200];  }

now instance lets wanted this:

container<fish> fishies = new container(); fishies.foreach(fish->system::out);

you need implement foreach method similar of stream interface in container class :

void foreach(consumer<? super t> action)  {     (int = 0; < array.length; i++)         action.accept(array[i]); }

this foreach implementation serial, it's simpler stream implementations, can parallel.

i'm ignoring fact t[] array = new t[200]; doesn't pass compilation, that's different issue.
