Along with the String, the array is the most used data structure in Java. In fact, String is also backed by a character array in Java and other programming languages. It's very important for a Java programmer to have good knowledge of array and how to do common things with array e.g. initialization, searching, sorting, printing array in a meaningful way, comparing array, converting an array to String or ArrayList and doing some advanced slicing and dicing operation with an array in Java. Like my previous tutorials 10 examples of HashMap in Java, I'll show you some practical examples of an array in Java. If you think, any important operation is not included, you can suggest their examples and I'll add them to this list.
Top 50 Java Coding and Programming Problems for Beginner Programmers
Hello guys, if you are learning to code and programming or preparing for a programming job interview and looking for some practice material then you have come to the right place. In this article, I am going to share some of the most common Java coding and programming problems for beginners. These are the problems, I have solved myself to learn to program and develop a coding sense. These programs are very simple but will teach you a lot about computer science, problem-solving, data structure, algorithms, programming languages, control structure and in general how to think of a solution and then translate into code. I call that coding sense and that's probably the most important thing for a programmer. It doesn't come overnight and it slowly develops when you utilize that part of your brain by solving coding problems.

Array-based questions are quite popular in Java interviews. There are two types of questions you will find, first which are based upon array implementation in Java and second which are based upon how to use an array data structure to solve some coding problems. The first type of question is quite popular in the telephonic round of Java interview and second is usually asked on written tests and face-to-face interviews.
Top 5 Free HTML and CSS Courses to Learn Frontend Web Development in 2020- Best of Lot
HTML and CSS are two pillars of web development, they are used to create web pages you see every day. HTML provides the structure to your web page, and CSS gives them the style to look better.

Top 5 Free Courses to learn Node.js in 2020 - Best of lot
Node JS has completely changed the way JavaScript is used for development. Earlier JavaScript was considered as a client-side language because it runs on a browser and mostly used for client-side validations, animations, and interaction. Node.js takes that to the next level by allowing JavaScript to run on a server-side, which means you can now write JavaScript applications that can execute without a browser. Node JS uses Google Chrome's execution engine and asynchronous processing to do this. All you need to is include node.js script in your application, and you are ready to create server-side applications in JavaScript, which wasn't possible until a few years back.
