Java / J2EE

Prerequiste: One must have programming knowledge in c c++ to become an expert in Java,ZeedUp will provide basic training on C,C++ before going into Java/J2EE Syllabus

Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented,[14] and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers “write once, run anywhere” (WORA),[15] meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.[16] Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture. As of 2016, Java is one of the most popular programming languages in use,[17][18][19][20] particularly for client-server web applications, with a reported 9 million developers.[21] Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems’ Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.


There were five primary goals in the creation of the Java language:

1.It must be “simple, object-oriented, and familiar”.

2.It must be “robust and secure”.

3.It must be “architecture-neutral and portable”.

4.It must execute with “high performance”.

5.It must be “interpreted, threaded, and dynamic”


J2EE (Java 2 Platform, Enterprise Edition) is a Java platform designed for the mainframe-scale computing typical of large enterprises. Sun Microsystems (together with industry partners such as IBM) designed J2EE to simplify application development in a thin client tiered environment. J2EE simplifies application development and decreases the need for programming and programmer training by creating standardized, reusable modular components and by enabling the tier to handle many aspects of programming automatically.

J2EE includes many components of the Java 2 Platform, Standard Edition (J2SE):

•The Java Development Kit (JDK) is included as the core language package.

•Write Once Run Anywhere technology is included to ensure portability.

•Support is provided for Common Object Request Broker Architecture (CORBA), a predecessor of Enterprise JavaBeans (EJB), so that Java objects can communicate with CORBA objects both locally and over a network through its interface broker.

•Java Database Connectivity 2.0 (JDBC), the Java equivalent to Open Database Connectivity (ODBC), is included as the standard interface for Java databases.

•A security model is included to protect data both locally and in Web-based applications.
