How to split this string using split function()

Question

I hava one string "2013-1-31 08:25 PM"

i want to split from space and :

i able to split after space it become "2013-1-31 08" and "25 PM"

String view_datee = view_date.getText().toString();

               String[] separated = view_datee.split(":");
               String first =separated[0];
               String second=separated[1]; 


               String[] newSeperated = first.split(" ");
               String third = newSeperated[0]; 
               String four=   newSeperated[1];



               Log.i("first",first);
               Log.i("second",second);

               Log.i("third", third);
               Log.i("four", four);

I do not how to get the four value means 08 .

Instead of splitting, you should parse the date and work on the date object. I will save you headaches and bugs. — assylias, Jan 30 '13 at 10:50
i am getting the date form the time picker so it is giving me the whole string — Amrinder, Jan 30 '13 at 10:52
Then you should definitely parse the date and work on a date object :) Check [this out](http://docs.oracle.com/javase/1.4.2/docs/api/java/text/SimpleDateFormat.html) — Less, Jan 30 '13 at 10:53

Here is an example using a date / calendar (it uses desktop java but easily transposable):

public static void main(String args[]) throws Exception {
    String data = "2013-1-31 08:25 PM";
    DateFormat fmt = new SimpleDateFormat("yyyy-MM-dd hh:mm a");
    Calendar cal = Calendar.getInstance();
    cal.setTime(fmt.parse(data));
    //2013-1-31
    System.out.println(new SimpleDateFormat("yyyy-M-dd").format(cal.getTime()));
    //20
    System.out.println(cal.get(Calendar.HOUR_OF_DAY));
    //08
    System.out.println(new SimpleDateFormat("hh").format(cal.getTime()));
}

Note that 08:25 PM is 20:05 so you can get either 08 or 20 depending on what you need. I showed both in my example.

Try this,

public static void main(String[] args) {
        String str = "2013-1-31 08:25 PM";
        System.out.println("[Date:"+str.split(" ")[0]+"][Hours:"+str.split(":")[0].split(" ")[1]+"]");
    }

Output,

run:
[Date:2013-1-31][Hours:08]
BUILD SUCCESSFUL (total time: 1 second)

From the official Javadoc, split takes a RegExp as argument.

So, you cannot use " " as split argument.

Instead, you should use "\s" to sepparate the string by whitespace.

Then, your code would be:

           String[] separated = view_datee.split(":");
           String first =separated[0];
           String second=separated[1]; 


           String[] newSeperated = first.split("\\s");
           String third = newSeperated[0]; 
           String four=   newSeperated[1];



           Log.i("first",first);
           Log.i("second",second);

           Log.i("third", third);
           Log.i("four", four);

Are u sure String ends with PM Or AM Then u can do like this

String s= "2013-1-31 08:25 PM";

        String newStr=s.substring(s.indexOf(" ")+1,s.lastIndexOf(" "));
        System.out.println(newStr);
        String result[]=newStr.split(":");
        System.out.println(result[0]);
        System.out.println(result[1]);

check below code, its working properly

String date = "2013-1-31 08:25 PM";
    String[] split = date.split(":");
    System.out.println(split[0]+"date:::"  + split[1] );
    String[] Datesplit = split[0].split(" ");
    System.out.println(Datesplit[0]+"date splited:::"  + Datesplit[1] );

Output below

2013-1-31 08date:::25 PM
2013-1-31date splited:::08

I have checked out your code and its working properly.. Here is i am posting whatever i have typed and excuted:

    String teststr = "2013-1-31 08:25 PM";
    System.out.println("teststr: " + teststr);
    String[] separated = teststr.split(":");
    String first = separated[0];
    String second = separated[1];
    String[] newSeperated = first.split(" ");
    String third = newSeperated[0];
    String four = newSeperated[1];
    System.out.println("first : "+first);
    System.out.println("second : "+second);
    System.out.println("third : "+third);
    System.out.println("fourth : "+four);

and its giving me following output: teststr: 2013-1-31 08:25 PM first : 2013-1-31 08 second : 25 PM third : 2013-1-31 fourth : 08
