It has gained traction and market share in essentially every programming environment, especially enterprise software, server-side Web development, and mobile phone programming.

James Gosling
It has been a long journey with many surprises along the way. That journey started in the early days with James Gosling and his team, who were sure that developers wanted advanced productivity features (such as object orientation and garbage collection), but felt that many engineers were scared off by the complexity of the languages that implemented them.
The High-Level Design of Java
In language design terms, Java has always been based on a number of deliberate, opinionated design decisions with specific goals in mind. The Java platform’s initial primary goals can be summed up as:
-
To provide a container for simple execution of object-oriented application code
-
