How to implement Command Design Pattern in Java with Example
Hello guys, it's been a long since I have shared a Java design pattern tutorial. I did share some courses to learn design patterns but haven't really talked about a particular design pattern in depth. So, today, we'll learn one of the important design pattern, which is often overlooked by Java developers. Yes, I am talking about the Command Pattern which can help you write flexible, loosely coupled code for implementing actions and events in your application. In simple words, the command design pattern is used to separate a request for action from the object which actually performs the action. This decoupling between Invoker and Receiver objects provides a uniform way to perform different types of actions. This decoupling is achieved using a Command object, which is usually an interface with methods like execute().
How to sort an Array in Java? Ascending and Descending Order Example
As a Java programmer, quite often you would need to sort array in Java luckily java.util.Arrays class provides several utility methods to sort an array in Java. You can sort different types of array in Java like array of primitive data types, object or int, String, etc. Arrays are in java.util package and exposed all sorting related methods as static utility functions. you can access sort() as Arrays.sort() and just pass your array and it will sort that array object by comparing them in the order implemented in the compareTo() method if the class implements Comparable interface. You can also sort arrays in ascending order, descending order, or any custom order defined by the custom comparator in Java.
How to loop through an Array in Java? Example Tutorial
Hello there, If you want to loop over an array in Java but not sure how to do that then you have come to the right place. Earlier, I have shared many Java array tutorials and the best Java courses for beginners, and today, I am going to teach you how to iterate over an array in Java. There are multiple ways to loop over an array in Java, like you can use a for loop, an enhanced for loop, a while loop, or a do-while loop. Since while and do-while needs a condition to terminate they often depend upon the content of the array like stop when the current element is null or even or odd etc. If you just want to iterate over an array to access each element like loop over an array and print each entry then you should use either for loop or the enhanced for loop.
How to declare and initialize a List with values in Java (ArrayList/LinkedList) - Arrays.asList() Example
Hello guys, today, I am going to share with you a useful tip to initialize a List like ArrayList or LinkedList with values, which will help you a lot while writing unit tests and prototypes. Initializing a list while declaring is very convenient for quick use, but unfortunately, Java doesn't provide any programming constructs like the collection literals of Scala, but there is a trick which you can use to declare and initialize a List at the same time. This trick is also known as initializing a List with values. I have used this trick a lot while declaring list for unit testing and writing demo programs to understand an API etc and today I'll you'll also learn that.

How to find Middle Element of Linked List in Java in Single Pass
ow do you find the middle element of LinkedList in one pass is a programming question often asked Java and non-Java programmers in telephonic Interview. This question is similar to checking palindrome or calculating the factorial, where the Interviewer sometimes also asks to write code. In order to answer this question candidate must be familiar with the LinkedList data structure i.e. In the case of the singly LinkedList, each node of Linked List contains data and pointer, which is the address of the next Linked List and the last element of Singly Linked List points towards the null. Since in order to find the middle element of the Linked List you need to find the length of the linked list, which is counting elements till the end i.e. until you find the last element of the Linked List.
How to implement Skip List in Java? Example Tutorial
Hello friends, we meet again today. hope you all are excited and ready for today's journey. Today, we are gonna learn something that is not very common. It is used not very common, but, if used, it is a great strength to our time complexity reduction. So, what's the wait? Let's start! So, suppose we have a linked list with us which has 10 million records. Now, for searching a particular node, the time taken would be O(N). Where N is the size of the list. Similarly, the time taken for deletion of a Node, Insertion at a particular Node will also take O(N) time. Can we reduce it?
[Solved] How to find the 3rd (kth) Node from end or tail in linked list in Java? Fast and Slow Pointer Example
Hello guys, the problem to find the 3rd element from the end in a singly linked list or Kth node from the tail is one of the tricky but frequently asked linked list problems in Programming job interviews. I know you can easily solve this problem by moving from tail to head or in the reverse direction but the main challenge here is to solve the problem in just one pass. That means, you can not traverse the linked list again and you cannot traverse backward because it's a singly linked list. So what do you think? Isn't this problem challenging? Well, I did struggle when I saw this problem very first time but once you understand the logic and some tricks to solve a linked list based problem like Recursion then it would be easy for you, and that's what you will learn in this article.

Can a Non Static Method Access a Static Variable/Method in Java?
"Can a non-static method access a static variable or call a static method" is one of the frequently asked questions on the static modifier in Java, the answer is, Yes, a non-static method can access a static variable or call a static method in Java. There is no problem with that because of static members i.e. both static variable and static methods belong to a class and can be called from anywhere, depending upon their access modifier. For example, if a static variable is private then it can only be accessed from the class itself, but you can access a public static variable from anywhere.
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 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 2023 - 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.
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.
