Core Java

Overview

The Core Java training course helps to understand the concepts of object-oriented programming and how it is implemented in the Java language. With our Core Java online training participants can get familiar with concepts such as inheritance, polymorphism, and abstraction as well as their implementation using class, objects, packages, and wrappers.

Objectives

At the end of Core Java training course, participants will be able to

  • Understand Java’s importance, uses, strengths and weaknesses

  • Understand the release cycle and Long Term Support (LTS) releases

  • Understand Java language basics

  • Write, compile, and run Java programs

  • Use the Java shell (JShell – Java 9+) for interactive programming

  • Understand the Object Model and Object-Oriented Programming

  • Understand and use classes, inheritance, polymorphism

  • Create well-designed classes and use them in your Java programs

  • Use composition and delegation to create objects from other objects

  • Understand & use packages to organize code

  • Understand and use Java 9 modules

  • Understand interfaces, their importance, and their uses

  • Use interfaces to implement abstraction

  • Learn good Java coding style

  • Create well-structured Java programs

  • Use the core Java libraries (java.lang, java.util)

  • Understand & use exceptions for error handling

  • Understand the basics of using JDBC and JPA, and use them to access databases from Java

  • Use other new features such as type inference

Prerequisites

This Core Java training course can be tailored for audiences ranging from first-time programmers to experienced OO developers seeking to learn Java. Basic programming knowledge is good to have but not mandatory.
