Java vs Python
Python is an object-oriented programming language that has large enormous library support making the implementation of various programs and algorithms easy. Java is a high-level, object-oriented programming language which was originally developed by James Gosling at Sun Microsystems in 1995. Java has a syntax similar to C and C++ but with low-level difficulties.
Java vs JavaScript
Java is an object-oriented programming language and has a virtual machine platform that allows you to create compiled programs that run on nearly every platform. JavaScript is a lightweight programming language(scripting language) and is used to make web pages interactive. It can insert dynamic text into HTML.
Spring vs Spring Boot
Spring is an open-source lightweight framework that allows Java EE 7 developers to build simple, reliable, and scalable enterprise applications. This framework mainly focuses on providing various ways to help you manage your business objects. Spring Boot is built on top of the conventional spring framework. So, it provides all the features of spring and is yet easier to use than spring. Spring Boot is a microservice-based framework and making a production-ready application in very less time.
Overloading vs Overriding
When two or more methods in the same class have the same name but different parameters, it's called Overloading. When the method signature (name and parameters) are the same in the superclass and the child class, it's called Overriding.
Object vs Class
Everything in Java is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake. A Class is like an object constructor, or a blueprint for creating objects.
