Java Programming: From Beginner to Enterprise-Level Development
Course Duration: 25 Hours
Suitable Crowd: Programming newbies, computer science students, developers looking to switch to back-end development, and anyone who wants to master a high-paying, enterprise-grade programming language
Have you ever wanted to break into the back-end development industry but didn’t know which language to choose?
Are you frustrated by not being able to understand enterprise-level project code or participate in team development?
Do you want to master a mature, stable, and high-demand programming language that can unlock high-paying jobs in fintech, e-commerce, and big data industries?
This Java Programming: From Beginner to Enterprise-Level Development video course is your comprehensive roadmap to mastering Java—the "king of back-end languages". In 25 hours of systematic, hands-on teaching, we’ll take you from a complete Java novice to a developer who can independently build simple enterprise-level projects and participate in team development. No prior programming experience is required—just your dedication and willingness to practice.
What You Will Master in This Course
Java Core Basic Syntax (Lay a Solid Foundation for Enterprise Development)
Java’s rigor is its advantage—learn to write standard, clean, and maintainable Java code from the start:
Environment setup: Step-by-step demos to install JDK, configure environment variables, and use IDE (IntelliJ IDEA) on Windows/Mac, solving common installation and configuration problems.
Core basic knowledge: Master variables, data types, operators, conditional statements, loop statements, arrays, and strings— the building blocks of all Java programs.
Exception handling: Learn to use try-catch-finally blocks to handle runtime exceptions, avoid program crashes, and improve the robustness of your code (a key requirement for enterprise development).
IO stream operation: Master basic byte streams and character streams to read and write files, laying the foundation for processing data in enterprise projects.
Practical exercise: Write a simple student score management system to consolidate basic syntax and realize data addition, deletion, modification, and query functions.
Object-Oriented Programming (OOP) (Master the Core of Java Development)
Object-oriented is the soul of Java—learn to think in an object-oriented way and build scalable, reusable code:
OOP core concepts: Deeply understand encapsulation, inheritance, and polymorphism—the three pillars of object-oriented programming, and master their practical application scenarios.
Class and object: Learn to define classes, create objects, and use constructors to initialize objects; master the use of access modifiers to achieve data encapsulation.
Abstract classes and interfaces: Master the differences between abstract classes and interfaces, and learn to use them to define standardization and achieve code decoupling (a key skill for enterprise project architecture).
Collection framework: Master commonly used collection classes (ArrayList, HashMap, HashSet) to store and manage complex data, replacing traditional arrays to improve development efficiency.
Practical exercise: Reconstruct the student score management system with object-oriented thinking, improve code reusability and scalability, and lay the foundation for enterprise-level project development.
Enterprise-Level Project Practice (Integrate Skills and Meet Workplace Requirements)
Consolidate all learned knowledge with a real enterprise-level project and gain practical development experience that can be directly applied to the workplace:
Project overview: Build a simple e-commerce order management system (a classic scenario in enterprise development), including user login, order creation, order query, and order cancellation functions.
Project architecture: Learn to use the layered architecture (presentation layer, business logic layer, data access layer) to build projects, which is the standard architecture for most enterprise Java projects.
Database integration: Master the basic use of JDBC to connect to MySQL databases, realize persistent storage of data, and solve the problem of data loss after program restart.
Project optimization: Learn to optimize code structure, add log records, and handle concurrent requests simply to improve the stability and maintainability of the project.
Team development specifications: Master basic Java development specifications (naming conventions, code formatting) to ensure that your code is consistent with team development requirements and easy for other developers to read and maintain.
After completing the project, you’ll have a tangible enterprise-level project to add to your personal portfolio—perfect for showcasing your skills to potential employers.
