Core Java 8 Training in Chennai

Java 8 will improve application performance without any specific work or tuning.Lambda expressions, the Streams API, and new methods on existing classes are some of the key productivity improvements.Java 8’s new Optional type gives developers significant flexibility when dealing with null values, reducing the likelihood of NullPointer Exceptions
