Come JDK 1.5 – we have the Java Generics, supposed to make type-safe container based programming a reality to the programmers. This paper tries to analyze the implementation of the Java Generics and its comparison with the templates of C++. In C++, templates provide one of the vehicles of ...

The recent Java 5 (a.k.a. Java 1.5) generics implementation opens both new problems and new opportunities in the implementation of the "Gang of Four" (GoF) Factory patterns [Gamma, et al 1995]. On the one hand, we want a class factory to determine the type it will instantiate at run...
Recently there has been a shift away from the traditional com- pile, link and run model of programming towards a more dynamic approach in which the division between compile-time and run-time becomes blurred. The two most significant examples of this trend are the Java Virtual Machine [11] ...
Type holes [10] have been identified also in Generic Java [9, 12]. Consequently, the following question arises: Is type safety preserved after adding generics as specified in the ECMA Standard [4]? So far, this question has only been addressed by Yu, Kennedy and Syme in [13]. They ...
The usage of the Generic types V2 and V3 equate to the names used in the Java definitions. The current type of the input into the Mapper is a string (this normally being V1). This is needed as the mapper, in Streaming jobs, performs the projection from the textual input. For...
