About The Course
Core Java is the fundamental part of Java used to build general-purpose applications. It covers core concepts like OOP (Object-Oriented Programming), Exception Handling, Collections, Multithreading, and JDBC — forming the base for advanced technologies such as Spring and Hibernate. Core Java is mainly a part of Java Standard Edition (Java SE) and is used to develop standalone and desktop-based applications.
Core Java includes fundamental concepts like syntax, OOP principles, collections, and exception handling, while Advanced Java encompasses frameworks, web development, database connectivity, and enterprise application development patterns — making Core Java the essential prerequisite that every developer must master first.
Core Java Training covers a combination of basic and advanced concepts, complex coding scenarios, hands-on labs and exercises, and real-world use cases — making learners expert in object-oriented programming, packages, exception handling, file handling, threading, collections, JDBC, Java 8 lambda expressions, and streams — to build enterprise applications
Core Java covers OOP, Collections, Exception Handling, and Multithreading — concepts used directly in every Advanced Java framework including Spring Boot and Hibernate. Advanced Java without Core Java leads to a shallow understanding, poor interview performance, and slow debugging on the job.

Java is a high-level, object-oriented programming language developed by Sun Microsystems (now Oracle). It is platform-independent because Java programs are compiled into bytecode, which can run on any system that has a Java Virtual Machine (JVM).
Java is called platform-independent because the source code is compiled into bytecode, which runs on the Java Virtual Machine (JVM). This allows the same Java program to run on different operating systems without modification.
JDK (Java Development Kit) is used to develop Java applications and includes the JRE and development tools such as the compiler. JRE (Java Runtime Environment) provides the libraries and environment needed to run Java programs. JVM (Java Virtual Machine) executes Java bytecode and makes Java platform-independent.
The four pillars of OOP are:
- Encapsulation: Wrapping data and methods into a single class.
- Inheritance: Creating a new class using an existing class.
- Polymorphism: Allowing one interface to have multiple implementations.
- Abstraction: Hiding implementation details and showing only essential functionality.
Method overloading occurs when multiple methods in the same class have the same name but different parameters. Method overriding occurs when a subclass provides its own implementation of a method that already exists in the parent class.
Multithreading allows multiple tasks to execute concurrently within a single program. It improves CPU utilization, increases application responsiveness, and is useful for tasks such as file processing, networking, and background operations.
An Array has a fixed size and can store primitive data types and objects. An ArrayList has a dynamic size, can grow or shrink automatically, stores objects only, and provides built-in methods for adding, removing, and searching elements.
The == operator compares whether two references point to the same object in memory. The equals() method compares the actual contents or values of two objects. For objects like String, equals() is commonly used to compare values.
