About Core Java course

What is Core Java?

The main idea of anything is referred to as “core,” whereas the fundamental idea of the Java programming language is referred to as “Core Java.” As is common knowledge, one of the most popular and widely used programming languages is Java, and a beginner should start with Core Java and work their way up to Advance Java. The object-oriented programming (OOPs) paradigm is the foundation of the general-purpose Java programming language. The ocean of Java is too deep to explore; that is, the more you understand, the deeper it gets. Programming with Java is a strong, cross-platform language. Java adheres to the Write Once, Run Anywhere (WORA) paradigm. The programming language is clear-cut and easy to understand.

Concepts Covered in Core Java

Some of the most crucial Java fundamentals for a beginner to understand are as follows:
