One of the nice addition in Java 8 is the java.time package that will streamline the process of working with time in java.This just happened to me yesterday. There was no standard approach or API in java for date and time in Java. It has always been hard to work with Date, Time, and Time Zones in java. Notice that parallel processing values are not in order, so parallel processing will be very helpful while working with huge collections.Ĭovering everything about Stream API is not possible in this post, you can read everything about Stream API at Java 8 Stream API Example Tutorial. If you will run above example code, you will get output like this: High Nums parallel = 91 High Nums parallel = 96 High Nums parallel = 93 High Nums parallel = 98 High Nums parallel = 94 High Nums parallel = 95 High Nums parallel = 97 High Nums parallel = 92 High Nums parallel = 99 High Nums sequential = 91 High Nums sequential = 92 High Nums sequential = 93 High Nums sequential = 94 High Nums sequential = 95 High Nums sequential = 96 High Nums sequential = 97 High Nums sequential = 98 High Nums sequential = 99 Integer public class Java8ForEachExample Let’s see forEach usage with a simple example. The forEach method takes object as an argument, so it helps in having our business logic at a separate location that we can reuse. Java 8 has introduced forEach method in interface so that while writing code we focus on business logic. We might get ConcurrentModificationException if the iterator is not used properly. Whenever we need to traverse through a Collection, we need to create an Iterator whose whole purpose is to iterate over, and then we have business logic in a loop for each of the elements in the Collection.

I will provide some code snippets for better understanding the features in a simple way. Let’s have a brief look on these Java 8 features. Java Stream API for Bulk Data Operations on Collections.Functional Interfaces and Lambda Expressions.default and static methods in Interfaces.Some of the important Java 8 features are Let’s look at all the exciting and major features of Java 8 with example code. It’s because it was a major release with a lot of new features. That’s a long time ago but still many projects are running on Java 8.
