So given the method
static boolean sameArgs(Integer a, Integer b) {
return a == b;
}
the following invocation returns
TRue
:
sameArgs(3, 3)
while this invocation returns
false
:
sameArgs(3, new Integer(3))
An implementation of the virtual machine may choose to expand on
these types and ranges, and is free to determine when instances of the
wrapper classes are first created: They could be created eagerly and all
stored in a lookup table, or they could be created as needed.
Dare to be naïve.
