For instance, Java has the first-class support for concurrency through an abstraction called the Thread class. This provides a system-independent definition for a thread in Java. However, under-the-hood, Java maps every thread to the kernel level thread through system calls. As we’ve already...

By definition, multitasking is when multiple processes share common processing resources such as a CPU. Multi-threading extends the idea of multitasking into applications where you can subdivide specific operations within a single application into individual threads. Each of the threads can run in ...

Java Concurrency Method 2: Executors and CompletionServices Another option is to use the API for managing groups of threads behind the curtain. Luckily, our wonderful JVM offers us exactly that with the Executor interface. The executor interface definition is quite simple: public interface Executor ...

Definition 1. (Method pending refactoring): In a program (P), given a set (M), collect all the methods to be refactored, 𝑀={𝑚1,𝑚2,...,𝑚𝑛}M={m1,m2,...,mn}. For ∀𝑚𝑖∈𝑀(1≤𝑖≤𝑛)∀mi∈M(1≤i≤n), it holds that ∃𝑠𝑠∈𝑚𝑖∃ss∈...
Programmers are often reluctant to employ immutable objects, because they worry about the cost of creating a new object as opposed to updating an object in place. The impact of object creation is often overestimated, and can be offset by some of the efficiencies associated with immutable objects...
