1. When you know the size, just use simple array, int[].
It's significantly faster without having to create
extra objects, calling a number of functions (including
inside the implementation as well).
2. Avoid autoboxing. It calls about 2+ functions and create
an object (a very expensive operation), both are
significantly slower.
3. Use StringBuffer to significantly reduce the memory usage
and runs significantly
