Core Java Training at Udeck Services Siliguri

Java continues to be one of the most widely used programming languages for building enterprise applications, backend systems, web applications and large-scale software solutions.

If you want to start your programming career or strengthen your Java fundamentals, Core Java Training at Udeck Services Siliguri is designed to help you understand Java programming from basic concepts to practical application development.

Our training focuses on learning through coding and practical implementation instead of relying only on theoretical concepts.

Whether you are a student, fresher or someone planning to move into software development, Core Java can provide a strong foundation for your development career.

What is Core Java?

Core Java refers to the fundamental concepts and features of the Java programming language.

It provides the foundation required before moving to technologies such as Spring Boot, Hibernate, REST APIs, Microservices and Java Full Stack Development.

During Core Java training, students learn how Java programs work and how object-oriented programming concepts can be used to build structured applications.

What Will You Learn in Core Java Training?

The Core Java course covers important concepts required to develop a strong programming foundation.

1. Introduction to Java

Students start by understanding Java fundamentals, including:

  • Introduction to Java
  • Features of Java
  • JDK, JRE and JVM
  • Installing and configuring Java
  • Writing your first Java program
  • Compilation and execution process

2. Java Programming Fundamentals

Build your programming foundation with:

  • Variables and Data Types
  • Operators
  • Type Casting
  • Conditional Statements
  • If-Else
  • Switch Statements
  • Loops
  • Arrays
  • Methods

These concepts help students understand programming logic and problem solving.

3. Object-Oriented Programming (OOP)

OOP is one of the most important areas of Java development.

Students learn:

  • Classes and Objects
  • Constructors
  • Inheritance
  • Polymorphism
  • Encapsulation
  • Abstraction
