讀取csv

com.csvreader.CsvReader

@Test
public void testReader() throws Exception {
    CsvReader r = new CsvReader("F://info.csv", ',', Charset.forName("GBK"));
    // 讀取表頭
    r.readHeaders();//先讀取表頭
    String[] headers = r.getHeaders();//獲取表頭的陣列
    System.out.println(Arrays.toString(headers));
    // 逐條讀取記錄，直至讀完
 

    while (r.readRecord()) {
        // 讀取一條記錄
        String rawRecord = r.getRawRecord();
        System.out.println(rawRecord);
    }
    r.close();
}

結果

[編號, 姓名, 性別, 年齡]
001,小明,男,21
002,小紅,女,18

寫入csv

com.csvreader.CsvWriter

@Test
public void testWriter() throws Exception {
    CsvWriter wr = new
 
 CsvWriter("F://info.csv", ',', Charset.forName("GBK"));
    // 寫表頭
    String[] headers = {"編號","姓名","性別","年齡"};
    wr.writeRecord(headers);
    // 寫內容
    List<String[]> contents = new ArrayList<String[]>();
    String[] row1 = { "001", "小明", "男", "21" };
    String[] row2 = { "002", "小紅", "女", "18"
 
 };
    contents.add(row1);
    contents.add(row2);
    for (String[] row : contents) {
        wr.writeRecord(row);
    }
    wr.close();
}
