Criticism Main article: Criticism of Java Criticisms directed at Java include the implementation of generics, speed, the handling of unsigned numbers, the implementation of floating-point arithmetic, and a history of security Recent updates to Java make it faster and easier to create powerful gaming applications-particularly Java 3D-is fueling an explosive growth in Java games. IE, no one will want to touch it with a 20ft pole.
The lack of metaprogramming imply a penality at run time with each abstraction, thus performance come to the cost of design in many cases.

Standard libraries provide a generic way to access host-specific features such as graphics, threading, and networking. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them. In Internet Explorer 8, for example, select Tools and then Manage Add-ons, and in Google Chrome, type chrome://plugins in the address bar.

Java is being attacked, and restricting it to one browser minimises the "attack surface". I've used nearly all main stream IDEs, those from MS and GNU, Borland..., eclipse is the absolute king, of IDEs, largely because of it's fast.
