Question

我该怎么做？

Year 2019, Month July, Date 30

以这种格式并且仅从Calendar（java.util）对象中准确

private String getCurrentDate() {
        Calendar calendar = Calendar.getInstance();
        SimpleDateFormat mdformat = new SimpleDateFormat("yyyy-MM-dd");
        return mdformat.format(calendar.getTime()); }

Answer 1

如果您只想使用日历：

Calendar c = Calendar.getInstance();
String result = "Year " + c.get(Calendar.YEAR) +
                ", Month " + new SimpleDateFormat("MMMM").format(c.getTime()) +
                ", Date " + c.get(DAY_OF_MONTH);
System.out.println(result);

将打印：

Year 2019, Month June, Date 4

如果您甚至不想使用SimpleDateFormat：

String[] months = {
        "January", "February", "March", "April", "May", "June",
        "July", "August", "September", "October", "November", "December"
};
Calendar c = Calendar.getInstance();
String result = "Year " + c.get(Calendar.YEAR) +
        ", Month " + months[c.get(Calendar.MONTH)] +
        ", Date " + c.get(DAY_OF_MONTH);
System.out.println(result);

还将打印：

Year 2019, Month June, Date 4

Answer 2

文本可以包含在SDF字符串中，因此请使用您的代码：

SimpleDateFormat mdFormat = new SimpleDateFormat("'Year 'yyyy', Month 'MMMM', Date 'dd");

此答案的目的是表明您可以在日期格式中包含文本； SDF有一些微妙之处（例如LLLL对于语言支持可能更好），此处未解决。

从这种格式获取当前日期2019-06-30
