Foil 148 Java Features -- It's Portable

From MetaComputing -- MRA Meeting Part I:Concepts and Issues Tutorial for CRPC MRA Meeting at Cornell -- May 7 1996. by Mark Baker, Geoffrey Fox
Java language offers a uniform abstract (virtual) machine model which is identical for all platforms. SUN owns the Java Virtual Machine (see online report) -- it is universal while classes can be added by any user.
Unlike in C/C++ where various integers match the architecture of a physical machine at hand, Java byte, char short, int and long are always of the same size, equal to 8, 16, 16 (unicode), 32 and 64 bits, respectively.
No header files, preprocessors, #define etc.
