Learn & Implement Under One Roof

Core Java

Core Java (8 Weeks/6 Months Max)

1. Java is a computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible.
2. It is intended to let application developers "write once, run anywhere" (WORA), which means that the code which runs on one platform does not need to be recompiled to run on another. Java applications are typically compiled to bytecode (class file) that can run on any Java virtual machine (JVM) regardless of computer architecture.
3. Java is, as of 2012, one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers.
4. Java was originally developed by James Gosling at Sun Microsystems (which has since merged into Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform.
5. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.

    For each individual course, students would be provided with sample projects. After reviewing the performance on the given projects, the best selected candidates will get a chance to work on live projects.
  • class participation
    'Participation' is the most important element to grow and learn more. Students should keep their minds active in each lecture to get the best of knowledge and if they come up with any queries, they can send a mail for the same. Keep clearing your doubts as and when it comes!
