is current density property of a material

 

j⃗ (t,x⃗ )=ρ(t,x⃗ )v⃗ (t,x⃗ ).
where ρ is charge density as a function of time and position and v is drift velocity of electrons as a function of time and position, in a conductor maintained at constant potential difference
??

is it that only having defined current density we can define current ??
