DISCUSSION
Consider the case if the smallest possible negative value of type long. This value,
9223372036854775808L, is allowed only as an operand of the unary minus operator
(§3.10.1). Therefore, enclosing it in parentheses, as in -(9223372036854775808L)
causes a compile time error.
In particular, the presence or absence of parentheses around an expression
does not (except for the case noted above) affect in any way:
• the choice of value set (§4.2.3) for the value of an expression of type float or
double.
• whether a variable is definitely assigned, definitely assigned when true, definitely
assigned when false, definitely unassigned, definitely unassigned when
true, or definitely unassigned when false (§16).

A class instance creation expression is used to create new objects that are
instances of classes.

A class instance creation expression specifies a class to be instantiated, possibly
followed by type arguments (if the class being instantiated is generic (§8.1.2)),
followed by (a possibly empty) list of actual value arguments to the constructor. It
is also possible to pass explicit type arguments to the constructor itself (if it is a
