[Java Code] 时间维度循环生成代码片段

public static void main(String[] args) throws ParseException {

String str1 = "20140731";
SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd");
Calendar start = Calendar.getInstance();

}
while (start.before(end)) {
System.out.println(format.format(start.getTime()));
start.add(Calendar.DAY_OF_MONTH, 1);
