, AnyMatch () returns a Boolean value. If a matching element is found, the next element traversal is stopped; boolean matched = list.stream().anyMatch((s) -> s.startsWith("A")); System.out.println(matched); // Output: true FindFirst (): returns the element. Similarly, only the first element is returned and not all elements are traversed; String firstMatchedName = list.stream().filter((s) -> s.startsWith("L")).findFirst().get(); System.out.println(firstMatched

Research on Android multithreading (8) -- Understanding Atomicity in Java and multithreading in android1. What is atomicity? Atomicity is the smallest unit in the world and is severable. For example, if the = 0; (a is not of the long and double types) type, this operation is an atomic operation. For example, a ++ is actually a = a + 1; it is split, so it is not an atomic operation.II. The role of atomic ope
