APPENDIX A -- OPERATOR PRECEDENCE TABLE

     The following table shows the precedence assigned to Java's operators.
     The operators in this table are listed in precedence order: the higher
     in the table an operator appears, the higher its  precedence. Operators
     with higher precedence are evaluated before operators with a relatively
     lower precedence. Operators on the same line have equal precedence.

      postfix operators
                     [] . (params) expr++ expr--
      unary operators
                     ++expr --expr +expr -expr ~ !
      creation or cast
                     new (type)expr
      multiplicative
                     * / %
      additive
                     + -
      shift
                     << >> >>>
      relational
                     < > <= >= instanceof
      equality
                     == !=
      bitwise AND
                     &
      bitwise exclusive OR
                     ^
      bitwise inclusive OR
                     |
      logical AND
                     &&
      logical OR
                     ||
      conditional
                     ? :
      assignment
                     = += -= *= /= %= &= ^= |= <<= >>= >>>=
 

     When operators of equal precedence appear in the same expression,
     some rule must govern which is evaluated first. In Java, all binary
     operators except for the assignment operators are evaluated in left
     to right order. Assignment operators are evaluated right to left.
