These are pretty specific functions, and I'd prefer to generalize them.  For example, what would the equivalent be for ObjectGrid2D?  What happens when you pass in null?

[Also: though good Java compilers will optimize this anyway, you should do things like this:]

for int x = 0 to width
int[] fieldx = field[x]
for int y = 0 to length
if fieldx[y] == from
fieldx[y] = to
