Web Reference: Jan 2, 2010 · 7 It is the Bitwise xor operator in java which results 1 for different value of bit (ie 1 ^ 0 = 1) and 0 for same value of bit (ie 0 ^ 0 = 0) when a number is written in binary form. ex :- To use your example: The binary representation of 5 is 0101. The binary representation of 4 is 0100. How do the post increment (i++) and pre increment (++i) operators work in Java?

YouTube Excerpt: Java 8 Full Guide for Developers and Interviews Java 8 is one of the most important releases in the history of Java. The introduction of Java 8 features like Lambda Expressions, Streams API, Functional Interfaces, Optional Class, Default Methods, Static Methods in Interfaces, and the new Java 8 Date and Time API completely transformed how modern Java applications are written. In this Java 8 tutorial, you will learn the most important Java 8 features in one video with clear explanations and practical IntelliJ hands-on coding examples. If you are preparing for Java 8 interview questions or want to strengthen your core Java concepts, this video will give you a strong conceptual understanding of the most widely used Java 8 features. In this video, we cover the following Java 8 features step-by-step: • Default Method in Interface • Static Method in Interface • Functional Interface • Lambda Expressions • Method Reference • Streams API • Optional Class • Java 8 Date and Time API • Metaspace You will also understand why Java 8 introduced default methods in interfaces, why static methods in interfaces were added, how lambda expressions simplify Java code, the advantages of method reference, how the Java Streams API works, how Optional in Java helps prevent NullPointerException, the benefits of the Java 8 Date-Time API, and how Metaspace replaced PermGen in Java memory management. This video works as a complete Java 8 overview where you get both theory and practical coding demonstrations. In upcoming videos, each Java 8 feature will be explained in much deeper detail with advanced examples and interview-focused discussions.
