I'm attempting to read data from a CSV file, then put each row into an object, then place the object inside an arraylists of objects. I seem to be getting an error on this line int age = fileReader.nextInt();

Can't seem to figure out what the issue is. Can anyone point me in the right direction?

Here is my full code:

package testfileio;

import java.io.FileNotFoundException;
import java.io.File;
import java.util.Scanner;
/**

public class TestFIleIO {

    /**
     * @param args the command line arguments
     * @throws java.io.FileNotFoundException
     */
    public static void main(String[] args) 
            throws FileNotFoundException {
        Company jam = new Company();
        
        File csv = new File("C:\\Users\\gregf\\Documents\\NetBeansProjects\\TestFIleIO\\employees.csv");
        Scanner fileReader = new Scanner(csv);
        
        fileReader.useDelimiter(",|\n");
        //skips first row (column headers)
        fileReader.nextLine();
        
        while(fileReader.hasNext()) {
            String name = fileReader.next();
            int age = fileReader.nextInt();
            fileReader.nextLine();
            
            try {
                jam.setEmployees(new Employee(name, age));
            }
            catch(Exception ex) {
                System.out.println(ex);
            }
        }
        
        System.out.println(jam);
    }
    
}

A few notes:

• Employee is an object with the name: String and age: int data fields

• Company is an object that contains an ArrayList of Employee type and has a toString method to print all the emplyoee names and ages.

Edit: Here is my error:

If I have an Excel file with columns of numerical values in and want to use these in a Java program how would I go about doing this?
In this case I have a few hundred rows of four-vectors (px, py, pz, E) and want to use the different values later on in the program (I can do this, it's just attempting to get the program to read them properly that's getting me stuck).
