In this article, I am going to share 21 of the most common String-based Programming and Coding interview questions from Java developer interviews. These questions require you to write code to solve the problem and they are different from traditional Java String questions like how substring method works in Java or when to use the intern() method of String in Java? Since coding and problem solving are an important part of any programming job interview, it's imperative that you know how to solve them in time and on a pressure situation, which comes only after doing practice with the right set of questions. Since these questions are already tried and tested and appeared in many interviews, they will provide you the experience you need to crack your coding interview.
What is Overloading, Overriding, Hiding, Shadowing and Obscuring in Java and Object-Oriented Programming?
Hello guys, today, I am going to explain a couple of fundamental object-oriented programing concepts in Java like Overloading, Overriding, Hiding, Shadowing, and Obscuring. The first two are used in the context of a method in Java while the last three are used in the context of variables in Java. Two methods with the same name and same class but the different signature is known as overloading and the method is known as an overloaded method while a method with same name and same signature but in parent and child class is known as overriding. On the other hand, Hiding is related to overriding since the static and private method cannot be overridden, if you declare such methods with same name and signature in parent and child class then the method in child class will hide the method in the parent class.
Top 5 Courses to learn System Design and Software Architecture in 2019- Best of Lot
Software design or System design is one of the tricky concepts to master. You can quickly learn a programming language like Java or Python, but creating software using that programming language is a totally different thing. That's where software design and coding skills comes to rescue. It's actually an art to structure your program, design your modules, specify boundaries and interactions with other parts of the system so that they are easier to read, maintain, and flexible to change. It's one of the most essential skills for a software developer but often gets ignored. If you look for an online course to learn Software design and architecture, you won't find many, forget about good ones.
