Java is almost universally recognized as a good object-oriented language for writing portable programs. However, it still lags behind Fortran and C in performance, particularly for computationally intensive numerical programs. In this paper we present a true multidimensional Array package, and related compiler support, that can bring Fortran-like performance to Java numerical codes. We discuss the main design principles for our Array package, and illustrate the benefits from its use through several examples.
