If the JVM is not able to detect the requested library, it throws an UnsatisfiedLinkError. Finally, the usage of native libraries makes a Java program more platform dependent, as it requires the existence of specific native libraries. 1. What is a java library and why we use it? A java ...
A class library -- or, simply,library-- is analogous to a subroutine library in earlier procedural programming. After importing a class library into an application, a developer can instantiateobjects-- create real instance of them -- based on the classes within the library. The developer can t...
What is Java? In this article, we explore the history of Java, its key features and benefits, and real-world examples of its applications.
Generally, Java compilers are run and pointed to a programmer's code in a text file to produce aclassfile for use by the JVM on differentplatforms. Jikes, for example, is anopen sourcecompiler that works in this way, and so does the primary compiler included in the Java Development Kit ...

MagicURLNetwork is a Java library which includes Mson to support JSON data transfer through networks. To make an URL connection, you only need to know what you want to do and choose an appropriate request method(GET, POST, PUT, HEAD...). You don't need t
A parser is a program that is part of the compiler, and parsing is part of the compiling process. Parsing happens during the analysis stage of compilation. In parsing, code is taken from the preprocessor, broken into smaller pieces and analyzed so other software can understand it. The parser...
TL;DR: What is an Object in Java? An object in Java is an instance of a class that can perform actions and store data, created with the syntax:MyClass myObject = new MyClass(). It’s a fundamental part of Java programming that allows you to encapsulate related data and behavior into...
