java - 如何从字符串中解析持续时间并添加它们？

Question

我需要在Java中解析两个HH:MM格式的字符串:

String time1="10:45";
String time2="02:30";

Answer 1

愚蠢但简单:

String time1 = "10:45";
String time2 = "02:30";

String[] split1 = time1.split(":");
String[] split2 = time2.split(":");

int total = 60 * Integer.parseInt(split1[0]) +
            Integer.parseInt(split1[1]) +
            60 * Integer.parseInt(split2[0]) +
            Integer.parseInt(split2[1]);

int hours = total / 60;
int minutes = total - hours * 60;
System.out.println(hours + ":" + minutes);
