Java Programming Concepts

Study Notes

Java Basics

Java is a platform-independent programming language developed by Sun Microsystems. It was released in 1995 and has since become one of the most popular programming languages. Java is known for its simplicity, reliability, and high performance, making it suitable for both standalone applications and web applications.

Object-Oriented Programming in Java

Java follows the principles of Object-Oriented Programming (OOP), organizing the code around objects, each representing an instance of a class. The key concepts of OOP in Java include abstraction, encapsulation, inheritance, and polymorphism.

Java Collections

The Java Collections Framework offers interfaces and classes for implementing various data structures and algorithms. Some commonly used collections in Java include Lists, Sets, and Maps, providing efficient storage and manipulation of data.

Multithreading in Java

Multithreading in Java enables simultaneous execution of two or more parts of a program for optimal CPU utilization. Java offers a robust multithreading model where each thread runs independently and shares none of the state of the other threads.

Exception Handling in Java

Exception handling in Java allows you to catch and deal with runtime errors. Java has a hierarchical structure for exceptions, with the Throwable class serving as the base. There are two main types of exceptions: checked exceptions (like IOException) and unchecked exceptions (such as NullPointerException).

Description

Explore fundamental concepts of Java programming including basics, object-oriented programming, collections, multithreading, and exception handling. Learn about Java's platform independence, code organization around objects, data structure implementations, simultaneous program execution, and handling runtime errors.
