将getTime（）的值转换为毫秒时出错

Question

请你帮忙解决以下问题：

我在显示器中出现错误，当我转换为毫秒时，它将显示错误的值。我在Java中使用getTime（）。

我的代码是：

Time absent = rs.getTime("abs_hours");
long absent_cumm= (absent.getTime() );

out.println(absent); // This will display 00:04:00 which is correct

但是当我打印absent_cumm时

out.println(absent_cumm);// This will display -10560000 which is wrong

如何将缺席值转换为毫秒？

Answer 1

嗯，至少有一种方法可行：

Time time = Time.valueOf("00:04:00"); // replace with rs.getTime()
Calendar cal = Calendar.getInstance();
cal.setTime(time);
int hour = cal.get(Calendar.HOUR);
int minute = cal.get(Calendar.MINUTE);
int second = cal.get(Calendar.SECOND);
int ms = (hour * 3600 + minute * 60 + second) * 1000;
System.out.println("ms: " + ms);

应正确打印“ms：240000”
