There are Stream objects that may have an encounter order depending on its source and the intermediate operations you have applied before. This encounter order imposes a restriction about the order in which the elements must be processed by certain methods. For example, if you use the limit() or skip() methods in Stream with an encounter order, they will get and ignore the first elements according to that encounter order. There are other operations, such as the forEach() method, that don't take into account the encounter order. If you apply the same operations to a stream with an encounter order, the result will always be the same. If the stream doesn't have an encounter order, the results may vary.
