Zero-based Java self-study tutorial

Java is a widely used programming language with the characteristics of cross-platform, security, portability, multi-threading, etc., so it is widely used in various software development fields. When learning Java programming, there are some key concepts and codes that Java beginners must master.

Zero-based Java self-study tutorial will provide you with basic Java syntax, object-oriented programming, exception handling, input and output streams, multi-threaded programming, collection framework, network programming, graphical interface programming, database programming, etc. A detailed Java learning guide. The following is a 4-week zero-based Java self-study tutorial plan:

Week 1: Java basic syntax and environment construction

1. Install Java development environment: Select Appropriate Java development tools, such as Eclipse, IntelliJIDEA, NetBeans, etc., must be installed and configured.

2. Basic Java syntax: Learn Java basic data types (byte, short, int, long, float, double, boolean, char), variables, constants, operators and expressions.

3. Control statements: Learn conditional statements (if, else, switch), loop statements (for, while, do-while) and jump statements (break, continue, return).

Week 2: Object-oriented programming and arrays

1. Object-oriented programming: Learn the concepts of classes and objects, the definition of classes, and the creation and use of objects.

2. Array: Learn the definition, creation, access and operation of arrays.

3. String processing: Learn the basic operations of strings (such as string splicing, interception, search, replacement, etc.) and the use of the String class.

Week 3: Exception handling, input and output streams and multi-threaded programming

1. Exception handling: Learn the basic concepts of exception handling, the definition of exception classes, try The use of -catch-finally statement.

2. Input and output streams: Learn the use of Java input and output stream classes, such as FileInputStream, FileOutputStream, BufferedReader, PrintWriter, etc.

3. Multi-threaded programming: Learn the creation, synchronization, communication and termination of threads, as well as the use of thread pools.

Week 4: Collection framework, network programming, graphical interface programming and database programming

1. Collection framework: Learn the use of Java collection framework, such as List and Set , Map, Queue, etc.

2. Network programming: Learn Java network programming APIs, such as URL, URLConnection, Socket, ServerSocket, etc., to realize functions such as network chat and file transfer.

3. Graphical interface programming: Learn Java graphical interface programming APIs, such as Swing, JavaFX, etc., and create simple graphical interface applications.

4. Database programming: Learn Java database programming APIs, such as JDBC, to connect and operate databases.

During the learning process, you can refer to some Java programming tutorials, books or online courses, such as "HeadFirstJava", "Java Core Technology", "EffectiveJava", etc. At the same time, practicing more, thinking more, and writing more code are the keys to improving Java programming skills. I hope this zero-based Java self-study tutorial can help you get started with Java programming smoothly.
