current is a scalar quantity but we know that the scalar quantities only have magnitude but current have direction too so is it a vector quantity if yes how? and if it is a scalar quantity so how it has the direction

Current itself is not a vector but for all numerical and mathematical purpose we use current density which is  a vector.
However there are some quantities which dont have any direction but a sense of direction, such uantities are called tensors
