What is Encapsulation in Java? Encapsulationis like putting things in a box and only allowing certain ways to interact with them. In programming, it means bundling data (variables) and methods (functions) that work with the data together in a single unit, often called a class. This helps in...
putIfAbsent()andcomputeIfAbsent()are two of them. We frequently used these two methods for adding entries. While they might seem similar at first glance, they have distinct behaviors and use cases. In this tutorial, we’ll discuss the difference between these two methods. 2. Introduction Before...
a TLS handshake occurs, so that the packets exchanged between the client and server are encrypted. In this scenario, akeystorecould be used. The keystore on the server would contain the public certificate
This is one of the tricky Java interview questions, which some of you might have encountered. There is a very subtle difference betweengetClass()and instanceof operator, which can cause potential issues with respect to theequals()method. Coming to the point, the key difference between them is...
I understand the concrete concepts of OOP (you make a class that has data (members) and functions (methods) and then instantiate that class at run time to actually do stuff, that kind of thing). I think I have a handle on what a class is (sort of a design blueprint for an ...

methods. The subclasses will have the option to chose between the base interface or the child interface to implement according to its requirements. If the number of methods grows a lot, it’s not a bad idea to provide a skeletal abstract class implementing the child interface and providing ...
What is the main difference between gumtree-spoon-ast-diff and gumtreediff?The tree of gumtree-spoon-ast-diff is carefully designed to provide better AST diffs for Java as opposed to vanilla gumtreediff. Simply compare the AST diffs on your own data. The nodes involved in the diff can ...
