if (0 <= ix && ix < array.length && array[ix] != 0) {
// ...
}
The range checks are done first. The value
array[ix]
will be accessed
only if
ix
is within bounds. There is no "conditional
XOR
" because the
truth of
XOR
always depends on the value of both operands.

instanceof
The
instanceof
operator evaluates whether a reference refers to an ob-
ject that is an instance of a particular class or interface. The left-hand
side is a reference to an object, and the right-hand side is a class or in-
9.2.5. Bit Manipulation Operators
The binary bitwise operators are:
bitwise
AND
&
bitwise inclusive
OR
|
bitwise exclusive or (
XOR
)
^
The bitwise operators apply only to integer types (including
char
) and
perform their operation on each pair of bits in the two operands. The
AND
of two bits yields a 1 if
both
bits are 1, the
OR
of two bits yields a 1 if
