Java将时间格式转换为整数或长整型(Java convert time format to integer or long)

Java将时间格式转换为整数或长整型(Java convert time format to integer or long)

我想知道什么是最好的方法是将00:00:00格式的时间字符串转换为整数或长整型？ 我的最终目标是能够将一串字符串时间转换为整数/长整型，将它们添加到数组中，并在数组中找到最近的时间......

我会很感激任何帮助，谢谢！

好的，根据答案，我决定继续直接比较字符串。 但是，我有一些麻烦。 可能有多个“最近的”时间，也就是说，如果两次相等。 如果是这种情况，我想将这两个时间的索引添加到ArrayList中。 这是我现在的代码：

days[0] = "15:00:00"; days[1] = "17:00:00"; days[2] = "18:00:00"; days[3] = "19:00:00"; days[4] = "19:00:00"; days[5] = "15:00:00"; days[6] = "13:00:00"; ArrayList<Integer> indexes = new ArrayList<Integer>(); String curMax = days[0]; for (int x = 1; x < days.length1; x++) { if (days[x].compareTo(curMax) > 0) { curMax = days[x]; indexes.add(x); System.out.println("INDEX OF THE LARGEST VALUE: " + x); } }

但是，这是将索引1，2和3添加到ArrayList ...

谁能帮我？

I'm wondering what the best method is to convert a time string in the format of 00:00:00 to an integer or a long? My ultimate goal is to be able to convert a bunch of string times to integers/longs, add them to an array, and find the most recent time in the array...

I'd appreciate any help, thanks!

Ok, based on the answers, I have decided to go ahead and compare the strings directly. However, I am having some trouble. It is possible to have more than one "most recent" time, that is, if two times are equal. If that is the case, I want to add the index of both of those times to an ArrayList. Here is my current code:

days[0] = "15:00:00"; days[1] = "17:00:00"; days[2] = "18:00:00"; days[3] = "19:00:00"; days[4] = "19:00:00"; days[5] = "15:00:00"; days[6] = "13:00:00"; ArrayList<Integer> indexes = new ArrayList<Integer>(); String curMax = days[0]; for (int x = 1; x < days.length1; x++) { if (days[x].compareTo(curMax) > 0) { curMax = days[x]; indexes.add(x); System.out.println("INDEX OF THE LARGEST VALUE: " + x); } }

However, this is adding index 1, 2, and 3 to the ArrayList...

Can anyone help me?

你可以通过比较字符串找到最近的时间，你不需要先转换成一个长的字符串。

例如

String[] times = { "12:23:45", "23:59:59", "00:00:00" } Arrays.sort(times); String firstTime = times[0]; String lastTime = times[times.length-1];

You can find the most recent time by comparing the strings, you don't need to convert to a long first.

e.g.

String[] times = { "12:23:45", "23:59:59", "00:00:00" } Arrays.sort(times); String firstTime = times[0]; String lastTime = times[times.length-1];
