Learn About Java

Java is one of the premier server-side languages of the Internet. Invented by Sun Microsystems in 1995, it has acquired an unparalleled reputation for scalability and utility. The large number of useful frameworks and libraries created for Java and a thriving developer community make it a favorite language for enterprise programmers.

Concentric Sky uses Java in our largest projects - those that must be able to handle millions of concurrent users across an array of servers and databases in an enterprise environment.
