Java：如何将字符串（HH：MM：SS）转换为持续时间？

我想将格式为HH：MM：SS或MM：SS或SS的字符串转换为持续时间的数据类型。

i want to convert a string with a format of HH:MM:SS or MM:SS or SS into a datatype of Duration.

解决方案：

    private ArrayList<Duration> myCdDuration = new ArrayList<Duration>();

        private void convert(String aDuration) {

            chooseNewDuration(stringToInt(splitDuration(aDuration))); //stringToInt() returns an int[] and splitDuration() returns a String[]
        }

        private void chooseNewDuration(int[] array) {
            int elements = array.length;
            switch (elements) {
            case 1:
                myCdDuration.add(newDuration(true, 0, 0, 0, 0, 0, array[0]));
                break;
            case 2:
                myCdDuration.add(newDuration(true, 0, 0, 0, 0, array[0], array[1]));
                break;
            case 3:
                myCdDuration.add(newDuration(true, 0, 0, 0, array[0], array[1],
                        array[2]));
                break;
            }
        }

感谢您的帮助......任何更简单的方法那个？ - >创建自己的Duration类：

thanks for help ... any easier way to do that ? -> create your own Duration class:

public class Duration {
        private int intSongDuration;
        private String printSongDuration;

        public String getPrintSongDuration() {
            return printSongDuration;
        }

        public void setPrintSongDuration(int songDuration) {
            printSongDuration = intToStringDuration(songDuration);
        }

        public int getIntSongDuration() {
            return intSongDuration;
        }

        public void setIntSongDuration(int songDuration) {
            intSongDuration = songDuration;
        }

        public Duration(int songDuration) {

            setIntSongDuration(songDuration);
        }

将int值转换为字符串以进行输出/打印：

Converts the int value into a String for output/print:

private String intToStringDuration(int aDuration) {
    String result = "";

    int hours = 0, minutes = 0, seconds = 0;

    hours = aDuration / 3600;
    minutes = (aDuration - hours * 3600) / 60;
    seconds = (aDuration - (hours * 3600 + minutes * 60));

    result = String.format("%02d:%02d:%02d", hours, minutes, seconds);
    return result;
}
