How to find If Linked List Contains Loop or Cycle in Java? Example Solution

Write a Java program to check if a linked list is circular or cyclic,  and how do you find if a linked list contains loop or cycles in Java are some common linked list related data structure interview questions asked in various Java Interviews. This is sometimes asked as a follow-up question of basic linked list questions like inserting an element at the beginning, middle and end of a linked list or finding the length of linked list. In order to solve linked list related algorithmic questions in Java, you need to be familiar with the concept of singly linked list, doubly linked list, and circular linked list. Until stated specifically, most questions are based on a singly linked list. For those who are not familiar with the linked list data structure, its a collection of nodes.

How to enclose a list of values into single quotes for SQL query? Microsoft Excel Example

Many times you get a list of values that you want to check in the database to confirm if they exist in your tables or to get more information bout them. For example, you got a list of 100 stocks and you want to check their last day closing prices in the database. The problem arises when values to be searched are Strings like VARCHAR or CHAR because VARCHAR values need to be enclosed in the single quotes in most of the database like SQL Server, Oracle, or MySQL. If a number of values are less than 5 then it makes sense to add single quotes around them and separate them by comma manually so that you can use them on IN clause of your SQL query, but if it's more than 5 like 50 or 100 then manually enclosing them into single quotes will take a lot of time and most importantly programmers are not supposed to do such silly stuff manually.

How to create Tabs UI using HTML, CSS, jQuery, JSP and JavaScript? Example

JSP is still a popular technology for developing view part of Struts and Spring-based Java applications, but unfortunately, it doesn't have rich UI support available in GWT, or any other library. On another day, we had a requirement to display HTML tables inside tabs, basically, we had two tables of different data set and we need to display them in their own tabs. Users can navigate from one tab to another, and CSS should take care of which tab is currently selected, by highlighting the active tab. Like many Java developers, our hands-on HTML, CSS, and JavaScript are a little bit tight than a web guy, and since our application is not using any UI framework, we had to rely on JSP to do this job.

Top 5 books to Learn Object Oriented Programming and Design - Must Read, Best of Lot

The OOP or Object Oriented Programming is one of the most popular programming paradigms which helps you to organize code in the real-world system. It's a tool that allows you to write sophisticated software by thinking in terms of objects and relationships. Unlike its predecessor procedural Programming paradigm, which is implemented most notably by C, which solves the problem and complete task by writing code for computers, the OOP style of programming allows you to think in terms of real-world objects which have both state and behavior. You can view anything as objects and then find their state and behaviors, this will help you to simulate that object in code.

Top 10 Websites and Online Platforms to Learn Git for FREE in 2022 - Best of Lot

Hello guys, like many programmers, I have also worked with a lot of source control systems like SVN, CVS, TFS, VSS, Mercury, and I had always wondered why so many source control systems? Why not just one. It's one of the necessary software tools for development, and everyone needs a version control and code repository, there should be a standard solution. It seems Git and Github have solved that problem now. Now, Git is everywhere from open source to closed source, from small startups to big Investment banks, but there were still legacy projects which were lying on SVN and CVS, but they are now also started moving towards it.

How to use Adapter Design Pattern in Java with Example

The adapter design pattern in Java, also known as the Wrapper pattern is another very useful GOF pattern, which helps to bridge the gap between two classes in Java. As per the list of Gang of Four patterns, the Adapter is a structural pattern, much like Proxy, Flyweight, Facade, and Decorator patterns in Java. As the name suggests, the Adapter allows two classes of a different interface to work together, without changing any code on either side. You can view the Adapter pattern as a central piece of the puzzle, which joins two pieces, which can not be directly joined because of different interfaces.

How to fix tibrvnative.dll : Can't load IA 32-bit .dll on a AMD 64-bit platform? Solution

Can't load IA 32-bit .dll on an AMD 64-bit platform is a generic error, which comes when a 64-bit process tries to load a 32-bit dll, but when it comes it's not that easy to resolve. One of my readers was getting this error tibrvnative.dll : Can't load IA 32-bit .dll on an AMD 64-bit when he was trying to install Tibco Rendezvous 8.2 on his Windows 8 HP Laptop. He was working on a Java application that was dependent upon Tibco Rendezvous for inter-process communication. After installing Tibco on his machine he was having a hard time running his Java application, first, he was getting errors like java.lang.UnsatisfiedLinkError: no tibrvnative in java.library.path and after resolving that he was getting a new error tibrvnative.dll: Can't find dependent libraries.

What is the Use of Interface in Java and Object Oriented Programming? [Answer]

Many times, I have seen questions like why should we use an interface in Java? If we can not define any concrete methods inside the interface the what is the user of the interface? Or even more common, What is the real use of the interface in Java? I can understand beginners asking this question when they just see the name of the method inside the interface and nothing else. It takes time to realize real goodness or actual use of interface or abstraction in Java or any object-oriented programming. One reason for this is a lack of experience in really modeling something real in the program using object-oriented analysis and design. In this article, I will try to answer this question and give you a couple of reasons to use the interface in your code. If you have a good understanding of Object-oriented basics like Polymorphism, then you know that it allows you to write flexible code.

Difference between Inheritance and Composition in Java and Object Oriented Programming

Though both Inheritance and Composition provide code reusability, the main difference between Composition and Inheritance in Java is that Composition allows reuse of code without extending it but for Inheritance, you must extend the class for any reuse of code or functionality. Another difference that comes from this fact is that by using Composition you can reuse code for even the final class which is not extensible but Inheritance cannot reuse code in such cases. Also by using Composition, you can reuse code from many classes as they are declared as just a member variable, but with Inheritance, you can reuse code from just one class because in Java you can only extend one class because multiple Inheritance is not supported in Java.
