Java 8 is a giant step forward for the Java language. Writing this book has forced me to learn a lot more about it. In Project Lambda, Java gets a new closure syntax, method-references, and default methods on interfaces. It manages to add many of the features of functional languages wit...
A Constructor in C++ is a special member function having the same name as that of its class, which is used to initialize some valid values to an object’s data members. It is executed automatically whenever an object of a class is created. The only restriction that applies to the construc...
This section describes what is a constructor - a special method to be invoked automatically when a new object is created from a class. The main purpose of the constructor is to provide initial values to object properties.
Processes and Threads are the essential elements of Java Concurrency. Mainly, they support creating an advanced execution environment in Java. In a way, it is a self-contained environment. Let’s look at them in detail below: Processes: A process is nothing but a complete and private set of...
