Description

Java syntax Basics

Basic syntax, array, class, inheritance, polymorphism, abstract class, interface, object, common class (Math \ Arrarys \ String \ StringBuffer, time class, System) final class, static class, Anonymous class, internal class, exception, encoding specification, Environment Configuration

 

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 programming

I/O watershed files (File \ FileFliter, File stream, text stream, data stream, buffer stream, object stream, byte \ character array stream, string stream, print stream, etc), multithreading, entity class, Collection class, enumeration \ iterator class, Graphic programming AWT (Java2D/mongoound/JMF) Swing, SWT, JFace, network Programming Applet, Socket/TCP/UDP, NIO, RMI, CORBA, selector, datagram/Socket/ServerSocket channel, regular expression, XML, and attribute File

 

Advanced features

Reflection, generics, annotators, automatic packing and unpacking, enumeration classes, variable parameters, variable return types, enhanced loops, static Import

Java Development Environment

JDK, JVM, Eclipse, and Linux

Stage 2: JavaEE junior software engineer

Web Development Technology

HTML, XML, CSS, JavaScript, AJAX

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.

 

Database Design Technology

JDBC, SQL, MySql, Oracle, SQLServer,

 

Java Web core development technology

Development Environment (Eclipse, Linux)
Three major components (JSP, JavaBean, Servlet)
Extension Technology (EL, JSTL, Taglib

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)

 

Web Server

Tomcat/Jetty/Resin/JBossWeb

Stage 3: JavaEE intermediate Software Engineer

Struts2 presentation layer framework

Entry configuration, core components, tag library, internationalization, data verification, Sitemesh integrated converter, interceptor, integrated Hibernate/iBATIS

 

Spring service layer framework

Hibernate Persistence Layer framework

Hibernate3.2 configure Configuration/SessinFactory/Session, O/R ing, Data Association, data retrieval, HQL, data cache, transaction management, MySQL, Oracle, SQLServer iBATIS persistent layer framework

 

EJB

Jboss installation and running, session Baen --> Publish the JNDI service, message-driven Bean
