我有一个字符串"1 hour 1 min"，我需要读61分钟。我该怎么办？

Answer 1

假设您一直在转换指定的格式，即xxx hour xxx min 您可以拆分字符串或使用正则表达式获取hour和min组件。

这是一个样本

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class ConvertTimeStringSample {
    public static int convertHourAndMinToMinutes(String toConvert) {
        // Parse the string matching the pattern
        Matcher matcher = Pattern.compile("(.*?) hour (.*?) min").matcher(toConvert);
        if(matcher.find()) {            
            int hoursInMinutes = new Integer(matcher.group(1)) * 60; // The hours part of the string converted to an integer and multiplied into minutes
            int minutes = new Integer(matcher.group(2)); // The minutes part of the string converted to an integer
            int totalMinutes = hoursInMinutes + minutes; // The sum of the two, making up the total minutes
            return totalMinutes;
        }
        throw new IllegalArgumentException("Unable to parse input string.");
    }

    public static void main(String[] args) throws IllegalArgumentException {
        String toConvert = "1 hour 1 min";
        int minutes = convertHourAndMinToMinutes(toConvert); // Call our conversion function
        System.out.println("Total in minutes: " + minutes); // Display  the result
    }
}

输出：

Total in minutes: 61

如何将字符串“ 1小时1分钟”转换为61分钟
