Yes, but the JLS strongly discourages that.

“Brackets are allowed in declarators as a nod to the tradition of C and C++. The general rules for variable declaration, however, permit brackets toappear on both the type and in declarators, so that the local variable declaration:

“ float[][] f[][], g[][][], h[]; // Yechh!

“We do not recommend "mixed notation" in an array variable declaration, where brackets appear on both the type and in declarators.”
