Threads are the fundamental model of program execution in a Java program, and the Java language and its API provide a rich set of features for the creation and management of threads. All Java programs comprise at least a single thread of control—even a simple Java program consisting of only...
OOP is a programming paradigmthat assumes centrality in Java because it allows for codes that are modular, reusable, maintainable, or easy to develop. The most characteristic features that it uses include classes and objects, encapsulation, inheritance, polymorphism, and abstraction. Introduction to Cl...
