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.

II. Java EE junior software engineer

JSF framework development technology
Configuration file (page navigation, backend bean), JSF Component Library (JSF El language, HTML Tag, event processing,), and JSF core library (format conversion, input verification, and internationalization)

Java Web core development technology
Development Environment (Eclipse, Linux)
Three major components (JSP, JavaBean, Servlet)
Extension Technology (El, jstl, taglib)

Web Development Technology
HTML, XML, CSS, JavaScript, Ajax
Database Design Technology
SQL, MySQL, Oracle, sqlserver, JDBC

Web Server (tomcat/jetty/resin/jbossweb)

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:
