How to read user input in hh:mm:ss without time class

[lbayne]

I am trying to design and implement a Java application that calculates and displays the elapsed time between two time values expressed in the 24-hour notation with the form hh:mm:ss. Assuming that the two times occur on the same day and that the “start” time occurs before the “finish” time. A typical program execution would look like the following:

Enter the start time (hh:mm:ss): 07:10:50
Enter the finish time (hh:mm:ss): 13:45:09

Elapsed Time = 06:34:19

I am not to use any of the Java Time Class functions. This is an exercise in string processing and algorithm development. The output should be formatted as shown(hh:mm:ss). The appropriate leading zeros need to be included.


The question is: What commands do I use to read in the time in hh:mm:ss format without using a Java Time Class function?

I've tried Scanner sc = new Scanner (System.in);
...
sc.NextInt();

It is not working and I don't know how to handle the colons.:confused:

Any help is appreciated.

Read the hh:mm:ss format as a String and parse it to three Strings using split or indexOf or StringTokenizer. Then convert the three strings to ints.
