29) How to perform Serialization and Deserialization? Use ObjectOutputStream for serialization and ObjectInputStream for deserialization. 30) What happens if you don't use serialization? Objects cannot be stored or transmitted as a byte stream, so when encounters error a java.lang. RuntimeException...
We can convert a Java object to a Stream that is called Serialization. Once an object is converted to Stream, it can be saved to file or send over the network or used in socket connections. The object should implement a Serializable interface and we can use java.io.ObjectOutputStream to ...
import java.util.stream.IntStream; void main() { IntStream.range(1, 10).reduce((x, y) -> x + y) .ifPresent(System.out::println); IntStream.range(1, 10).reduce(Integer::sum) .ifPresent(System.out::println); IntStream.range(1, 10).reduce(MyUtil::add2Ints) .ifPresent(System.ou...
Stream<Integer> intStream = IntStream.rangeClosed(0, 9).boxed(); Stream<String> arrayStream = Arrays.stream(newString[]{"a", "b", "c"}); Stream.generate(Math::random).limit(10).forEach(System.out::println);//无限流Stream.iterate(0, t -> t + 2).limit(10).forEach(System.out...
