Separating hours from minutes in a given time value

Question

I'm currently working on a simple Time-Manager Application for Android Devices. My Problem: I am getting a time value (that looks like this -> 6:51) from a Server. Now I want to separate the hours and minutes and I want the value to be updated continuously.

I have already looked into joda-time but cannot find anything myself that would solve my problem, if there is a solution in joda-time at all.

Should I try extracting the digits and build my time-format out of them or is there a better and simpler solution? In case of you recommending me to extract the digits, how do I solve the problem with hours above 9.

Thanks for Help and sorry for bad english.

Split the time.

 String time="6:51"              //which is from server;
 String splitTime[]=time.split(":");
 String hours=splitTime[0];
 String minutes=splitTime[1];

Better preparing an array first and then fill it **once** by using split, in order to minimize the split operations. – Phantômaxx Oct 22 '14 at 07:56
Wroks perfectly fine and is pretty simple! Thank you. – Vic Torious Oct 22 '14 at 08:08

If the string that you have is in the format hh:mm, then you can use String.split to separate them.

String arr [] = time.split(":");

Are you getting time from server as String "6:51" ?

org.joda.time.LocalTime#parse(String) will help you. LocalTime represent time without date. After parsing String you will be able to call methods getHourOfDay,getMinuteOfHour.

Just parse the value of time as String and use split to separate hours and minutes. Then, you can convert it to int again for future uses.

String Time = (String) time;
String Hour=time.split(":")[0];
String Minute=time.split(":")[1];
//If you want to use Hour and Minute for calculation purposes:
int hour=Integer.parseInt(Hour);
int minute=Integer.parseInt(Minute);

There should be no problem, if hours>9

In Joda-Time 2.5.

LocalTime localTime = LocalTime.parse( "6:51" );
int hour = localTime.getHourOfDay();
int minute = localTime.getMinuteOfHour();
