Java core Programming Technology

Java, a well-designed language. To learn Java, you must start from the Java development environment, to the Java syntax, and then to the Java core API.

1. Java Development: installation and use of the Java development environment, including JDK commands, eclipseide, and development and deployment of Java programs in Linux.

2. java syntax basics: develop Java core functions based on the JDK and eclipse environment, master the Java object-oriented syntax structure, including class, abstract class, interface, final class, static class, Anonymous class, internal class, and exception writing.

3. Java core API: based on the class library provided by JDK, master three core functions:

A. Java core programming: includes two core functions of Java programming-Java input/output stream and multithreading, and common auxiliary class libraries-entity classes, collection classes, regular expressions, XML and attribute files.

B. Java graphical programming: Includes Sun's GUI library AWT (Java2D, mongoound, JMF) and Swing, IBM and GUI library SWT and Jface;

C. Java Network Programming: Applet component programming, Socket programming, NIO non-blocking Socket programming, RMI and CORBA distributed development.

4. java advanced features: master the Java advanced features in JDK1.4, JDK5.0, and JDK6.0, including reflection, generics, and annotations, and advanced java features-automatic packing and unpacking, enumeration classes, variable parameters, variable return types, enhanced loops, static imports, and so on.

Core Java Web technologies:

The entire process of Java Web project development can be divided:

Webpage development + Database Design --> javaweb project development. javaweb consists of six basic technologies: JSP + JavaBean + servlet + EL + jstl + taglib, while JSF is a technical framework that organically combines these six technologies:
