  Motivated by recent experiments revealing superconductivity in MoS$_2$, we
investigate the Josephson effect in the monolayer MoS$_2$ at the presence of an
exchange splitting. We show that the supercurrent reversal known as $0-\pi$
transition can occur by varying the doping via gate voltages. This is in
contrast to common superconductor/ferromagnet/superconductor junctions in which
successive $0-\pi$ transition take place with the variation of junction length
or temperature. In fact for the case of MoS$_2$ we find that both the amplitude
and the period of oscillations show a dependence on the doping which explains
the predicted doping induced supercurrent reversal. These effects comes from
the dependence of density and Fermi velocity on the doping strength beside the
intrinsic spin splitting in the valence band which originates from spin-orbit
interaction.
