Core Java Internship Program

Core Java refers to the basic and fundamental components of the Java programming language. It encompasses the essential concepts, syntax, and libraries that form the foundation for Java development. Here are some key aspects of  Core Java Internship Program.

Object-Oriented Programming: Java is an object-oriented programming language, and Core Java emphasizes the principles of encapsulation, inheritance, and polymorphism. It provides classes, objects, interfaces, and other OOP features to structure and organize code.

Syntax and Basic Constructs: Core Java covers the syntax and basic constructs of the language, such as data types, variables, operators, control flow statements (if-else, loops), exception handling, and input/output operations.

Java Standard Library: Core Java utilizes the Java Standard Library, which includes a vast collection of classes and packages that provide ready-to-use functionality. It covers areas like collections, input/output, networking, multithreading, date/time handling, and more.

Classes and Objects: Core Java teaches the concept of classes and objects, which are used to model real-world entities. It covers topics like constructors, instance and static variables, methods, access modifiers, and inheritance.

Packages and Modules: Java organizes code into packages to manage class and resource files effectively. Core Java introduces the concept of packages and teaches how to create, import, and use packages to organize code. It also covers the module system introduced in Java 9.

Exception Handling: Core Java includes exception-handling mechanisms to deal with runtime errors. It covers try-catch blocks, handling multiple exceptions, creating custom exceptions, and best practices for exception handling.

Multithreading: Core Java covers the basics of multithreading, which allows concurrent execution of multiple threads. It teaches thread creation, synchronization, coordination, and common thread-related concepts like race conditions, deadlock, and thread safety.

Input/Output (I/O): Core Java covers file handling and input/output operations, including reading from and writing to files, standard input/output streams, serialization, and deserialization.

Generics: Core Java introduces generics, which enable the creation of type-safe collections and classes. It covers using generics with classes, methods, and interfaces to provide compile-time type checking.

Java Collections Framework: Core Java teaches the Java Collections Framework, which provides a set of classes and interfaces for storing, manipulating, and processing collections of objects. It includes concepts like lists, sets, maps, iterators, and algorithms for searching, sorting, and manipulating collections.
