No.

Got enough question marks there?

See
http://docs.oracle.com/javase/specs/jls/se7/html/jls-8.html#jls-8.4

"MethodHeader:
"  MethodModifiers[opt] TypeParameters[opt] Result MethodDeclarator Throws[opt] "

http://docs.oracle.com/javase/specs/jls/se7/html/jls-8.html#jls-8.4.4

"A method is /generic/ if it declares one or more type variables (§4.4).
"These type variables are known as the type parameters of the method. The form of the type parameter section of a generic method is identical to the type parameter section of a generic class (§8.1.2)."

etc.
