Could someone help me solve/ understand this part?

Use the following process to create each new song. Read the input values from the user into temporary variables. You will need to do some manipulation of the playing time data. The play time will be entered in the format mm: ss, where mm is the number of minutes and ss is the number of seconds. You will need to convert this string value to the total number of seconds before you can store it in your Song object. All other input values are String objects, so you can store them directly in your Song object. Use the Song constructor to instantiate a new song, passing in the variables containing the title, artist, play time, and file path. Because a copy of the values will be stored in your song objects, you can re-use the same temporary variables when reading input for the next song. Before moving to the next step, print your song objects to make sure everything looks correct
