Why can't I find my File?

Question

I\'m trying to open a CSV file name \"logger.csv\" which I have saved in the source folder itself.

public static void main(String[] args) {
    String filename =         


        

Answer 1

To see where the file is expected update the code in your catch clause to:

        System.out.println("Error: File not found: " + motor_readings.getAbsolutePath());

Put it there and be sure to refresh your workspace in Eclipse so that the file can be seen.

Answer 2

Put the file on level up. In the main folder of the project.

Answer 3

If you use relative pathing as you are right now - the file needs to exist in the project root, not in the directory of the java file.

Consider this hierarchy:

project/
  src/main/java
    file.java
    logger.csv

new File("logger.csv") will not work.

project/
  logger.csv
  src/main/java
    file.java

new File("logger.csv") will now work. (notice, the file is adjacent to the src directory.)
