Current is scaler because it is produced due to drift movement of charge and current density is vector because current per unit area which means in particular wire current flows,and that wire have particulare surface area,so this surface area have its normal vector which is perpendicular to that surface area, so j=I/A(vector) ,any scaler quantity divided by vector is vector quantity. So current density is vector quantity
