About of Java Programming

Java is a programming language originally developed by James Gosling, Mike Sheridan, and Patrick Naughtoninitiated the Java language project in June 1991.originally designed for small, embedded systems in electronic appliances like set-top boxes.initially called Oak and was developed as a part of the Green project In 1995, Oak was renamed as "Java". Java is just a name not an acronym.originally developed by James Gosling at Sun Microsystems (which is now a subsidiary of Oracle Corporation) and released in 1995.  The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to byte code that can run on any Java virtual machine (JVM) regardless of computer architecture.

The original and reference implementation Java compilers, virtual machines, and class libraries were originally released by Sun under proprietary licences. As of May 2007, in compliance with the specifications of the Java Community Process, Sun relicensed most of its Java technologies under the GNU General Public License. Others have also developed alternative implementations of these Sun technologies, such as the GNU Compiler for Java (byte code compiler), GNU Classpath (standard libraries), and Iced Tea-Web (browser plugin for applets).

  1. There were five primary goals in the creation of the Java language.
  2. It must be "simple, object-oriented and familiar".
  3. It must be "robust and secure".
  4. It must be "architecture-neutral and portable".
  5. It must execute with "high performance".
  6. It must be "interpreted, threaded, and dynamic".
