The system cannot find the file specified in java

Question

I am making a program that opens and reads a file. This is my code:

import java.io.*;

public class FileRead{
    public static void main(String[] args){
           


        

Answer 1

When you run a jar, your Main class itself becomes args[0] and your filename comes immediately after.

I had the same issue: I could locate my file when provided the absolute path from eclipse (because I was referring to the file as args[0]). Yet when I run the same from jar, it was trying to locate my main class - which is when I got the idea that I should be reading my file from args[1].
