写操作：

List
    
      data = new ArrayList
     
      ();data.add(new String[] { "A", "B", "C" });data.add(new String[] { "1", "2", "3" });data.add(new String[] { "A1", "B2", "C3" });FileWriter fw = new FileWriter(new File("c:/linkrmb.com.csv"));final CSVPrinter printer = CSVFormat.EXCEL.print(fw);printer.printRecords(data);printer.flush();printer.close();
     
    

读操作：

String path = "c:/linkrmb.com.csv";InputStream inputStream = new FileInputStream(path);InputStreamReader isr = new InputStreamReader(inputStream);Iterable
    
      records = CSVFormat.EXCEL.parse(isr);for (CSVRecord record : records) {	for (String string : record) {		System.out.print(string);		System.out.print("-");	}	System.out.println();	System.out.println("*****************");}
