Hello, I have a question. assuming, all letters below are either true or false. Are the following the same: 1. (A OR B) && (C) && (D OR E OR F OR G OR H) 2.

(A OR B) && (C) && (D OR E OR F OR G OR H) > 2. A OR B && C && D OR E OR F OR G OR H There is no OR in Java. Assuming that you mean ||, no, they are not the same, just as: (a + b) * (c) * (d + e + f + g + h) is not the same as: a + b * c * d + e + f + g + h  SignatureJohn W.
