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 to appear 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.”
<http://docs.oracle.com/javase/specs/jls/se7/html/jls-10.html#jls-10.2>
Know. Don't guess. Read the JLS.
