Wabsteid For Java Developers

Java is a computer programmin leid that is concurrent, class-based, object-orientit, an specifically designed tae hae as few implementation dependencies as possible. It is intendit tae let application developers "write ace, run onywhaur" (WORA), meanin that code that runs on ane platform daes nae need tae be recompiled tae run on anither. Java applications are typically compiled tae bytecode (class file) that can run on ony Java virtual machine (JVM) regardless o computer airchitectur. Java is, as o 2012, ane o the maist popular programmin leids in uise, particularly for client-server wab applications, wi a reportit 9 million developers.[10][11] Java wis originally developed bi James Gosling at Sun Microsystems (which haes syne merged intae Oracle Corporation) an released in 1995 as a core component o Sun Microseestems' Java platform. The leid derives much o its syntax frae C an C++, but it haes fewer low-level facilities nor either o them.

"Niklaus Wirth's lecture at the Polytechnic Museum in Moscow". ), that the Sun Java design team licenced the Oberon compiler sources a number of years prior to the release of Java and examined it: a (relative) compactness, type safety, garbage collection, no multiple inheritance for classes -- all these key overall design features are shared by Java and Oberon.
