If the operation y = x; is performed, then the result of (x = = y) is
a) trueb) false
c) x being set to the value null while y retains the value "Hello"
d) y being set to the value null while x retains the value "Hello"
e) x being set to y, which it is already since y = x; was already performed
Answer: a.
Explanation: When y = x; was performed, the two variables are now aliases, that is, they reference the same thing in memory. So, (x = = y) is now true.
