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]+"]");
        }
