Stream anyMatch() in Java with examples
Stream anyMatch(Predicate predicate) returns whether any 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 anyMatch(Predicate<? super T> predicate) Where, T is the type of the input to the predicate and the function returns true if any elements of the stream match the provided predicate, otherwise false.
Note : If the stream is empty then false is returned and the predicate is not evaluated.
Below given are some examples to understand the implementation of the function in a better way.
Example 1 : anyMatch() function to check whether any element in list satisfy given condition.
Example 2 : anyMatch() function to check whether any element in list having UpperCase at 1st index.
