java获取当前时间并格式化代码实例

private static final DateTimeFormatter FORMAT_FOURTEEN = DateTimeFormatter.ofPattern("yyyyMMddHHmmss");
private static final DateTimeFormatter FORMAT_DATE = DateTimeFormatter.ofPattern("yyyyMMdd");
private static final DateTimeFormatter FORMAT_NINETEEN = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");

public static void main(String[] args) {
  System.out.println(FORMAT_FOURTEEN.format(LocalDateTime.now()));
  System.out.println(FORMAT_DATE.format(LocalDateTime.now()));
  System.out.println(FORMAT_NINETEEN.format(LocalDateTime.now()));
}
