 import java.io.IOException;
 import java.util.ArrayList;
 import java.util.List;
 
 import au.com.bytecode.opencsv.CSVReader;
 import au.com.bytecode.opencsv.CSVWriter;
 
 public class ProcessCSV {
     private static final String ADDRESS_FILE="D://examples/addresses.csv";
     
     public static void main(String[] args) throws IOException {
         CSVWriter writer = new CSVWriter(new FileWriter(ADDRESS_FILE));
         List<String[]> allElements = new ArrayList<String[]>();
         allElements.add(new String[]{"张三","地址1","邮箱1"});
         allElements.add(new String[]{"李四","地址2","邮箱2"});
         
         writer.writeAll(allElements);
         writer.close();
         System.out.println("\nGenerated CSV File:" + ADDRESS_FILE);
         
         CSVReader reader = new CSVReader(new FileReader(ADDRESS_FILE));
         String [] nextLine;
         while ((nextLine = reader.readNext()) != null) {
             System.out.println("Name: ["+nextLine[0]+"]\nAddress: ["+nextLine[1]+"]\nEmail: ["+nextLine[2]+"]");
