Java Programming: Course Details, Fees, Syllabus, Core Concepts, Career Path
Esha GuptaAssociate Senior Executive
Java was first released by Sun Microsystems in 1995 and has evolved to become one of the most widely used programming languages and computing platforms in the world. It is a class-based, object-oriented language designed to have as few implementation dependencies as possible, making it a versatile choice for developers across various domains. Java is a high-level programming language known for its portability across platforms, from mainframe data centres to smartphones.
Its philosophy, "Write Once, Run Anywhere" (WORA), highlights its cross-platform capabilities, enabling Java applications to run easily on any device that has the Java Virtual Machine (JVM) installed. This unique feature has made Java very important for many web and mobile applications, enterprise-level solutions, and even in the world of big data and IoT (Internet of Things).

Java Programming Basics
At its core, Java is about creating fast, secure, and reliable applications. It is structured so that it is easy for beginners to learn while being robust enough for advanced programming tasks. Java's syntax is similar to C++ but boasts simpler object-oriented programming capabilities, garbage collection, and an extensive standard library (Java API).
Java's use extends from server-side applications to games and mobile apps. Its ability to scale from small tasks to complex systems makes it a preferred language for various projects and organizations.
Java's growth and evolution over the years have been driven by an active community of developers who continue to expand its capabilities and libraries. As a result, Java has adapted to the changing landscape of technology and remained a front-runner in the programming world.
Core Concepts of Java Programming
Concept |
Description |
Object-Oriented Programming |
Java is fundamentally object-oriented, emphasizing concepts like classes, objects, inheritance, encapsulation, abstraction, and polymorphism. |
Classes and Objects |
In Java, a class is a blueprint for creating objects (a particular data structure), including their states (attributes) and behaviours (methods). |
Inheritance |
Java allows classes to inherit attributes and methods from other classes, promoting code reusability and a hierarchical classification of classes. |
Encapsulation |
This principle restricts direct access to some of a component's components, which can prevent the accidental modification of data and can also be used to change the data later. |
Abstraction |
Abstraction in Java means dealing with ideas rather than events, focusing on what an object does instead of how it does it. |
Polymorphism |
Java supports polymorphism, allowing methods to perform different functions based on the object that invokes them. |
Interfaces and Abstract Classes |
Interfaces define methods that a class must implement without providing the method's body, while abstract classes can have both abstract and concrete methods. |
Exception Handling |
Java provides robust error handling with try, catch, finally, and throws keywords, promoting the handling of runtime errors and maintaining normal application flow. |
Multithreading |
Java supports multithreading, which allows concurrent execution of two or more parts of a program for maximum utilization of the CPU. |
Garbage Collection |
Java automatically manages memory allocation and de-allocation, freeing the programmer from manual memory management chores. |
Java API |
Java's extensive set of libraries (API) provides functionalities that can be readily used in applications, ranging from data structures to networking utilities. |
Advanced Java Concepts
Category |
Details |
Deployment and Server Knowledge |
Understanding deployment processes and servers like Weblogic, WebSphere, JBOSS, and Tomcat is crucial for Java Developers. |
APIs and Utility Libraries |
Familiarity with Java APIs and utility libraries such as Google Guava and Apache Commons is important to complement JDK libraries and aid in development. |
ORM Tools |
Knowledge of Object Relational Mapping tools like EclipseLink, OpenJPA, MyBatis, and TopLink is beneficial for data management and integration in Java applications. |
General Development Skills |
Skills in GIT (for version control), HTTP(S) protocol, Docker (for containerization), and Jenkins (for continuous integration and continuous deployment) are important for overall project management and efficient workflow. |
Cloud Deployment |
Mastery in cloud deployment using platforms like AWS, Azure, Google Cloud, and Heroku is increasingly relevant, highlighting the importance of cloud computing in modern Java development. |
How to Become a Java Developer?
Here are a few steps to consider when you want to learn and excel in Java Programming Language.
