What Is Java?
Java is an object-oriented programming language and software platform that operates on billions of devices, including laptop computers, mobile devices, game consoles, medical equipment, and more. Java is based on the C and C++ programming languages in terms of rules and grammar. Java is utilized as a computing platform.

Features Of Java
a. Simple: Java is straightforward to learn, with a syntax that is basic, clear, and easy to comprehend. C++’s baffling and unclear ideas have either been removed or re-implemented in a clearer manner in Java. Pointers and Operator Overloading, for example, are not present in Java but are very crucial in C++.
b. Object-Oriented Design: Everything in Java is an object with some data and behavior. Because it is built on the Object Model, Java can be readily expanded. The following are some fundamental OOP concepts:
c. Platform-unaffected: Unlike other programming languages such as C, C++, and others, which are compiled into machine-specific platforms. Java is a language that is guaranteed to be write-once, run-anywhere. A Java program is compiled into bytecode during compilation.
This bytecode format is platform-agnostic, meaning it may be executed on any system, and it also provides security. Java programs may be executed on any system that has the Java Runtime Environment installed.
d. Robust: Java tries to decrease error-prone code by focusing on compile-time error checking and runtime error checking. However, by integrating automated Garbage Collector and Exception Handling, Java significantly improved Memory Management and mishandled Exceptions.
e. Secure: Java is always the top option when it comes to security. We can construct a virus-free, tamper-free system using Java’s security capabilities. Java programs operate in the Java runtime environment with little contact with the operating system, making them more secure.
f. Threading in multiples: The multithreading capability of Java allows programmers to create programs that can do many tasks at once. Multithreading has the advantage of allowing numerous threads to run at the same time using the same memory and other resources. Grammar and spelling mistakes are checked as you type.

The type of each variable that a programmer creates does not need to be identified. Both systems have pros and downsides, but the primary benefit of static type checking is that it identifies type errors early in the development process, and code frequently executes faster or consumes less memory since the compiler knows precisely what data types are being used. The primary advantage of dynamic type checking is that it boosts programmer productivity by allowing you to assign types anytime you choose.
3. Prototype-based/Class-based: Class-based inheritance is a top-down, hierarchical, class-based relationship in which properties are declared in a class and inherited by a class instance (one of its members).
As with any language, the decision comes down to what you’re attempting to do and the resources you have available.
You should consider Java if your project involves any of the following:
a. Android Apps
b. Software for Businesses
c. Computing in Science
d. Analytics of Big Data
e. Hardware Programming for All Purposes
f. Apache, JBoss, Geronimo, and other server-side technologies
a. Single-page dynamic apps (SPAs)
b. jQuery, AngularJS, Backbone.js, Ember.js, ReactJS, and other front-end technologies
c. Node.js, MongoDB, Express.js, and other server-side technologies
d. PhoneGap, React Native, and other frameworks are used to create mobile apps.
