IntStream noneMatch() in Java with examples
IntStream noneMatch(IntPredicate predicate) returns whether no elements of this stream match the provided predicate. It may not evaluate the predicate on all elements if not necessary for determining the result. This is a short-circuiting terminal operation. A terminal operation is short-circuiting if, when presented with infinite input, it may terminate in finite time.
boolean noneMatch(IntPredicate predicate) Where, IntPredicate represents a predicate (boolean-valued function) of one int-valued argument and the function returns true if either all elements of the stream match the provided predicate or the stream is empty, otherwise false.
Note : If the stream is empty then true is returned and the predicate is not evaluated.
Example 1 : noneMatch() function to check whether no element of IntStream is divisible by 5.
Example 2 : noneMatch() function to check whether no element in the IntStream obtained after concatenating two IntStreams is less than 2.
Example 3 : noneMatch() function to show if the stream is empty then true is returned.
