abstract = {The measurements of the inclusive J/$\psi$ yield at
midrapidity ($\left | y \right | < 0.9$) and forward
rapidity (2.5 $< y <$ 4) in Pb$-$Pb collisions at
$\sqrt{s_{\mathrm{NN}}}=5.02$ TeV with the ALICE detector at
the LHC are reported. The inclusive J/$\psi$ production
yields and nuclear modification factors, $R_{\rm AA}$, are
measured as a function of the collision centrality, J/$\psi$
transverse momentum ($p_{\rm T}$), and rapidity. The
J/$\psi$ average transverse momentum and squared transverse
momentum ($\langle p_{\mathrm{T}}\rangle$ and $\langle
p_{\mathrm{T}}^{\mathrm{2}}\rangle$) are evaluated as a
function of the centrality at midrapidity. Compared to the
previous ALICE publications, here the entire Pb$-$Pb
collisions dataset collected during the LHC Run 2 is used,
which improves the precision of the measurements and extends
the $p_{\rm T}$ coverage. The $p_{\rm T}$-integrated $R_{\rm
AA}$ shows a hint of an increasing trend towards unity from
semicentral to central collisions at midrapidity, while it
is flat at forward rapidity. The $p_{\rm T}$-differential
$R_{\rm AA}$ shows a strong suppression at high $p_{\rm T}$
with less suppression at low $p_{\rm T}$ where it reaches a
larger value at midrapidity compared to forward rapidity.
The ratio of the $p_{\rm T}$-integrated yields of J/$\psi$
to those of D$^{0}$ mesons is reported for the first time
for the central and semicentral event classes at
midrapidity. Model calculations implementing charmonium
production via the coalescence of charm quarks and
antiquarks during the fireball evolution (transport models)
or in a statistical approach with thermal weights are in
good agreement with the data at low $p_{\rm T}$. At higher
$p_{\rm T}$, the data are well described by transport models
and a model based on energy loss in the strongly-interacting
medium produced in nuclear collisions at the LHC.},
