Introduction to Java| High Level, Robust, Object-Oriented, Secure - Episode 2

Java is high level, robust, object-oriented and secure programming language. Let’s understand each term one by one.

High level vs Low level – High level languages are those which are similar to human languages and these can be easily understood. However low-level languages are those which are represented in binary form 0 or 1. These are close to machine language and hard to understand. Since Java is human understandable that’s why it is high level.

Robust – Robust means strong. Any robust product is the one which doesn’t break easily. In computer programming terms robustness is related to the capacity of a system to handle the errors during execution. Since Java provides various in-built ways to handle errors like compile time error checking, memory management, garbage collection etc., so it is a robust language These terms may not be understood at this moment but we will be discussing all these in detail later.

Object Oriented – Object oriented language as the name suggests orientation towards object. Object is the entity which has state and behavior. For example, we can pick any item around us like mobile, computer, table, chair anything. We are surrounded by objects. So, the language which is revolved around the concept of object or you can say everything is based on object, that is object-oriented language. As Java is the programming language in which without classes and objects, we cannot create programs, so it is object-oriented language.

Secure – Java is secure language. How? Let’s understand. The programs written in Java are converted to bytecode first. This bytecode is verified and tested for any unsafe or unsecure operation. This is similar to security check, if any person is suspected then he/she is not allowed to pass through. Similarly, Java has capability to identify and stop any unwanted or unsafe operation before execution.
