Core Java
Overview:
Core Java serves as the fundamental building block for Java programming language. It encompasses essential concepts such as object-oriented programming (OOP), platform independence, and robustness. Core Java is used to develop standalone applications, desktop GUI applications, and backend server applications. It forms the basis for advanced Java development, including web application development using frameworks like Servlets and JSP.
Course Objectives:
- Master Java Fundamentals: Understand Java syntax, data types, variables, operators, control structures (loops, conditionals), and methods.
- Object-Oriented Programming (OOP): Learn key OOP principles such as classes, objects, inheritance, polymorphism, and encapsulation in Java.
- Exception Handling: Implement exception handling to manage runtime errors effectively in Java applications.
- File Handling: Read from and write to files using Java I/O classes, including streams and readers/writers.
- Collections Framework: Utilize Java’s built-in collections (lists, sets, maps, etc.) for data manipulation and organization.
Multithreading: Develop concurrent Java applications using threads to achieve parallel execution and improve application performance. - Networking: Understand networking concepts in Java for developing client-server applications using sockets and APIs like HTTP.
- GUI Development: Build graphical user interfaces (GUIs) using JavaFX or Swing for desktop applications.
- Database Connectivity: Connect Java applications to relational databases (MySQL, PostgreSQL, etc.) using JDBC for data manipulation and retrieval.
- Unit Testing: Implement unit tests using JUnit framework to ensure code reliability and maintainability.
Prerequisite / Target Audience:
This course is designed for beginners and intermediate programmers aiming to become proficient in Java programming. No prior knowledge of Java is required, but familiarity with basic programming concepts such as variables, loops, functions, and conditional statements is recommended. It is suitable for students, professionals, and anyone interested in software development with Java.
