j(current density)=nev ,now as electron is negative charge and current is flow of electron

This has no scientific reasoning behind it but rather historical one. Benjamin Franklin, like most other scientists during his time (before the discovery of electron) thought the charge carriers were positive so they gave the direction of current which assumed positive charge carriers. But even after electron being discovered it would have been confusing to change all the conventions to match the flow of electrons so the old convention wasn't abolished. read less

Conventional Direction of Current : Although electrons would flow from negative to positive, by convention (agreement), physicists refer to conventional current as a flow from high potential/voltage (positive) to low potential/voltage (negative).

Conventional Direction of Current : Although electrons would flow from negative to positive, by convention (agreement), physicists refer to conventional current as a flow from high potential/voltage (positive) to low potential/voltage (negative). Reminding you that potential is like electrical height, this means that conventional current flows "downhill", which makes sense Electrons move from areas where there are excess of negative charges to areas where there are a deficiency (or positive charge). Electrons move from "-" to "+", but conventional current is considered to move in the opposite direction. When you set up a circuit, conventional current is considered to move from the "+" to the "-" side. The idea about using positive charges in forming explanations comes from Benjamin Franklin. In Franklin's day, we didn't know about protons and electrons. Franklin believed that something moved through electrical wires, and he called these things "charge". He assumed there was only one kind of charge, and he logically assumed that charge would flow from a spot that had an excess (extra), to a spot that had a deficiency (too few). He called the spot with an excess "positive" and the spot with a deficiency "negative". So, for Franklin, charge flowed from positive to negative. We simply honor his achievements by continuing with this idea. read less

In 1752, prior to electricity being identified with the electron, Ben Franklin chose a convention regarding the direction of current flow. Franklin assumed that electrons (being assumed positive) flow from positive to negative terminals.We now know this is incorrect. The charge on an electron is negative by definition (note negative sign): (-1.6x10-19 C) The flow of electrons is termed electron current. Electrons flow from the negative terminal to the positive. Conventional current or simply current, behaves as if positive charge carriers cause current flow. Conventional current flows from the positive terminal to the negative. It is important to realize that the difference between conventional current flow and electron flow in no way effects any real-world behavior or computational results. In general, analyzing an electrical circuit yields results that are independent of the assumed direction of current flow. Conventional current flow is the standard that most all of the world follows. read less

It's just a convention. The direction of current is not taken as opp.of flow of positive charge to avoid further confusion.
