oracle數據庫,定義的TIMESTAMP類型,從數據庫中取出作時間對比的時候,發現取出是Sun Oct 24 20:49:20 CST 2021這種格式,需要轉換為常見的日期格式作對比
public static void main( String[] args )
{
String t1 = "Sun Oct 24 20:49:20 CST 2021";
String t2 = "Sun Oct 24 20:49:21 CST 2021";
SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy", Locale.US);
Date d1 = null;
Date d2 = null;
try {
d1 = sdf.parse(t1);
d2 = sdf.parse(t2);
} catch (ParseException e) {
e.printStackTrace();
}
sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println(sdf.format(d1) + "-----");
System.out.println(sdf.format(d2) + "-----");
if (sdf.format(d1).compareTo(sdf.format(d2)) == 0) {
System.out.println("時間相等");
}
}
