it runs on a multiple platforms such as UNIX, Windows, Mac OS. The Java language’s programming is based on the concept of OOP. We will see this in detail in later part of this Java Tutorial.
Choose collections over arrays for greater flexibilityCopy heading link While arrays in Java are efficient and easy to use, they are also fixed in size and offer limited operations, making them less adaptable for various data manipulations. Collections in Java provide far more flexibility and utiliti...
The Services Framework introduces a higher-level API for implementing services with NATS. NATS has always been a strong technology on which to build services, as they are easy to write, are location and DNS independent and can be scaled up or down by simply adding or removing instances of th...
This book also consists of a plethora of practice problems. Plus, after each chapter, the author sums up the topic and adds many supplementary exercises and solutions. That can help readers focus more on the book and learn Java more efficiently. 14. Mastering Java Machine Learning Mastering Jav...
One of the common programming exercises on various Java courses is the addition and multiplication of two arrays.How do you add two integer arrays in Java?Can you add two String arrays? how about other data types etc? These are some of the interesting questions becauseJava doesn't support op...
Avoiding excessive use of null is a good practice. For example, it’s preferable to return empty arrays or collections from methods instead of nulls, since it can help prevent NullPointerException. Consider the following method that traverses a collection obtained from another method, as shown be...

Parallel Array Sorting The Parallel Array Sorting feature adds the same set of sorting operations currently provided by theArraysclass, but with a parallel implementation that utilizes the Fork/Join framework. Additional utility methods were added tojava.util.Arraysthat use the JSR 166 Fork/Join para...
Again Statement is dependent on Connection. Without having a Connection object we cannot create a Statement object. Considering these facts it will take a lot of time to learn. ⬆ Back to Top What is Boilerplate code? What are the problems if we write the boilerplate code? The ...
String templates.The practice of embedding variables or simple expressions into strings isn’t popular. One reason is that it’s a bit cumbersome and the code is not perfectly readable. But more importantly, if the embedded content comes from the user, there’s the risk of injection attacks....
