List<First> listfirst(String dir){    
        try {           
            List<First> list=new ArrayList<First>();                       
            CSVReader reader = new CSVReader(new FileReader(dir));
            String [] nextLine;
            while ((nextLine = reader.readNext()) != null) {
             // nextLine[] is an array of values from the line
            list.add(new First(nextLine[0], nextLine[1], nextLine[2],nextLine[3], nextLine[4],nextLine[5], nextLine[6], nextLine[7]));

这就是我建议的阅读内容:

读取文件

import au.com.bytecode.opencsv.CSVReadProc;
import java.util.Arrays;

csv.read("example.csv", new CSVReadProc() {
    public void procRow(int rowIndex, String... values) {
        System.out.println(rowIndex + ": " + Arrays.asList(values));
    }
});
