break or continue java 8 stream lambda foreach(loop)

If you need this, you shouldn’t use forEach, but one of the other methods available on streams; which one, depends on what your goal is.

For example, if the goal of this loop is to find the first element which matches some predicate:

Optional<SomeObject> result =    someObjects.stream().filter(obj -> some_condition_met).findFirst();

(Note: This will not iterate the whole collection, because streams are lazily evaluated - it will stop at the first object that matches the condition).

If you just want to know if there’s an element in the collection for which the condition is true, you could use anyMatch:

boolean result = someObjects.stream().anyMatch(obj -> some_condition_met);
