You convert your java.sql.Timestamp to a java.sql.Date and send it through a Calendar.
您将 java.sql.Timestamp 转换为 java.sql.Date 并通过日历发送它。
java.sql.Timestamp ts = rs.getTimestamp(1);
java.util.GregorianCalendar cal = Calendar.getInstance();
cal.setTime(ts);
System.out.println(cal.get(java.util.Calendar.DAY_OF_WEEK));

If tsis your Timestampobject then to get the month in string format:
如果ts是您的Timestamp对象，则以字符串格式获取月份：
String month = (new SimpleDateFormat("MMMM")).format(ts.getTime()); // "April"
and for the day of the week:
以及一周中的哪一天：
String day = (new SimpleDateFormat("EEEE")).format(ts.getTime()); // "Tuesday"
回答by Michael Konietzka
SimpleDateFormatwill provide a Localespecific representation using the pattern "EEEE":
SimpleDateFormat将使用模式提供特定于区域设置的表示"EEEE"：
public static final String getDayName(final java.util.Date date, final java.util.Locale locale)
{
SimpleDateFormat df=new SimpleDateFormat("EEEE",locale);
return df.format(date);
}
Example usage:
用法示例：
System.out.println(getDayName(new Date(),Locale.US));
returns Tuesday.
返回Tuesday。
But beware that new SimpleDateFormat(..)is expensive.
但要注意new SimpleDateFormat(..)是昂贵的。
