13 best Java complete course using Visual Studio Code

Define Java Programming-

It is the process of developing applications for software using the Java programming language. It was developed by Sun Microsystems (now owned by Oracle Corporation) in the mid-1990s.

It is a high-level, object-oriented programming language that is used for making mobile apps, web apps, desktop apps, games, and many more apps.     

It is widely used for making applications of web coding. Developers can choose popular programming languages like to grow their scope in programming. Developers use millions of web applications.

Java is a multi-platform and also a network-centric language that can be used as a platform in itself.

The step-by-step setup and instruction of Java using Visual Code:-

  • Introduction of Java and Visual Studio code- you get an introduction. you get an overview of Java programming, how to install Java Development Kit(JDK), and all the setup for the Visual Studio code for the development.
  • Getting started with Java- is the first step before starting a new project on Java programming. It is for beginners, who want to do their project first time using Programming. Here, you can learn after completing the project how to run and compile the code using the project.  
  • Basic Java Syntax- syntax is very important while writing code because the code cannot work. learn to write in code and give the command. types of syntax that are used in variables and data types, operators and expressions, and control flow statements.
  • Object-Oriented Programming (OOP) Concepts- it is an object-oriented programming language that learns its concepts such as classes and objects, methods, constructors, inheritance, polymorphism, encapsulation, and abstraction.
  • Advanced OOP Concepts- understand the advanced concepts of OOP by using abstract classes and interfaces, inner classes, and enums.
  • Exception Handling- it explains how to handle the exception while programming by using try, catch, finally, and custom exception.
  • Collections Framework- discuss the main collections of frameworks that are used in Java programming like set, list, and map. It also explains the different ways to iterate over collections and how to use streams.
  • File I/O- it provides the input and output to the compilers and provides reading from and writing to files.
  • Java 8 and Beyond- here, you get the details about lambda expressions, stream API, and optional classes.
  • Multithreading and Concurrency- it explains how to create and run the threads and multi threads. Discuss the techniques of synchronization to handle concurrent access to resources and use the utilities of concurrency.
  • Building GUI Applications- learn how to build applications of GUI and understand the basics of JavaFX and how to set up and also follow the step-by-step guide to create a basic application of JavaFX.
  • Testing and Debugging- after completing the testing, checking errors is a must. learn how to write and run the unit tests and how to use the debugger.
  • Java Development Best Practices- understand the organization of code and modularity. how to name the Java conventions, documentation, comments, and Version Control with Git.

By following this structured outline, aspiring entrepreneurs and students can learn programming comprehensively using Visual Studio Code as their development environment.

Here are some key aspects of Java programming:-

Key Features of Java:-

  1. Object-Oriented: it is built around the concept of objects and classes, which allows for modular, reusable code and easier maintenance.
  2. Platform-Independent: Java’s “write once, run anywhere” philosophy is enabled by the JVM, which allows bytecode to be executed on any platform without modification.
  3. Simple and Familiar: it is designed to be easy to learn and use, with a syntax that is similar to C++ but with simpler and more streamlined features.
  4. Secure: it has built-in security features that help protect against common vulnerabilities, such as buffer overflows and unauthorized access.
  5. Robust: Java emphasizes reliability with strong memory management, exception handling, and type checking.
  6. Multithreaded: it has built-in support for multithreading, allowing for concurrent execution of two or more threads for maximum utilization of CPU.
  7. High Performance: While interpreted languages are generally slower than compiled languages, Java’s Just-In-Time (JIT) compiler improves performance by compiling bytecode into native machine code at runtime.
  8. Distributed: it is designed to support distributed computing, making it easier to build applications that can run on a network or the internet.

6 Basic Components of Java:-

  1. Classes
  2. Objects
  3. Methods
  4. variables
  5. Data types
  6. Control flow statement

Java Development Process:-

  1. Writing Code: Write your code in a text editor or an Integrated Development Environment (IDE) like Eclipse, IntelliJ IDEA, or Visual Studio Code.
  2. Compiling: Use the compiler (javac) to compile the source code into bytecode (.class files).
  3. Running: Execute the compiled bytecode using the Java interpreter, which runs the program on the JVM.

Standard Libraries and APIs:-

Java comes with a rich set of standard libraries and APIs that provide essential functionality, including:

  • java.lang: Fundamental classes and interfaces, such as String, Math, System, etc.
  • java.util: Utility classes, including collections framework, date and time facilities, and more.
  • java.io: Classes for input and output through data streams, serialization, and file handling.
  • java.nio: New I/O classes for non-blocking I/O operations.
  • java.net: Classes for networking applications.
  • javax.swing: Classes for building graphical user interfaces (GUIs).
  • java.sql: Classes for accessing and processing data stored in a relational database.

Conclusion

Java programming is a powerful and versatile skill that allows developers to create a wide range of applications, from web and mobile apps to large-scale enterprise systems. Its object-oriented nature, platform independence, and extensive standard libraries make it a popular choice for developers worldwide.
