Java is a programming language, which has been influenced by C language. It derives much of its C and C ++ syntax, however it has fewer low-level installations than any. J2EE is a computing platform based on the Java programming language. A computer platform allows you to run the software developed.
Java is a programming language, which has been influenced by C language. It derives much of its C and C ++ syntax, however it has fewer low-level installations than any. Java is a general purpose programming language that is designed to have fewer implementation dependencies compared to previous languages. It is concurrent, class-based and object-oriented language.
Java was developed by James Gosling at Sun Microsystems and was released in 1995. It was originally released as a core component of the Sun Microsystems Java platform. Sun has re-licensed most of its Java technologies under the GNU General Public License. This means that all the technology licensed under the GNU General Public License is open source and generally available at no cost. Sun Microsystems finally merged with Oracle Corporation.
Java is designed to allow the same code to run on multiple platforms. That is, developers are allowed to "write once, run anywhere" (WORA). Therefore, Java applications are typically compiled into bytecode. A class file containing a Java bytecode can be run on any Java virtual machine (JVM). This would be independent of the architecture of the computer.
As of 2012, Java has become one of the most popular programming languages to use. This is especially true for client-server web applications. Many other systems have developed alternative implementations of Sun technologies, such as GNU Compiler for Java and Classpath GNU.
C ++ and Java originate from the same point, that is, the C language. However, they have different design goals. C ++ was originally designed for programming systems and applications, while Java was initially created as an interpreter for printing systems. Java finally grew to support network computing.
The main difference between Java and J2EE is that while Java is a programming language, J2EE is a computing platform based on the Java programming language. A computer platform allows you to run the software developed. It contains the architecture of the computer, the operating system and the Runtime libraries. It also contains a hardware architecture and software framework, as well as an application framework.
Based on Java 2 Platform, Standard Edition (J2SE) as a base, Java 2 Platform, Enterprise Edition (J2EE) relies on this to provide the types of services that are required to build large-scale, Level. Essentially, J2EE is a collection of APIs that can be used to build these systems, although this is only half the image. J2EE is also a standard for creating and deploying enterprise applications, coupled by the specifications of the APIs you define and the services that J2EE provides. In other words, this means that the "write once, run anywhere" promises of Java also apply to enterprise applications:
• Enterprise applications can run on different platforms that support the Java 2 platform.
• Enterprise applications are portable among application servers that support the J2EE specification.
