What doesn't work about it?

If you mean contiguous structures, then no.  Sadly, Java can not pack 
multiple objects in a single block of memory like C/C++ can.  (If you're 
curious what for:  Vectors, pixels, voxels, particles, neural networks, 
database rows, etc.  Millions or billions of identical objects packed 
together for very fast access and efficient storage.)
