In the split function do not use . because it's a Regular Expression special character and need to be escaped: \\.

You can also parse date using 

SimpleDateFormat sdf = new SimpleDateFormat("dd.MM.yyyy");
String dateInString = "05.08.2010";
Date date = sdf.parse(dateInString);

EDIT

Now you can access day / month / year using (see this thread)

Calendar cal = Calendar.getInstance();
cal.setTime(date);
int year = cal.get(Calendar.YEAR);
int month = cal.get(Calendar.MONTH);
int day = cal.get(Calendar.DAY_OF_MONTH);

If you just want to print it out you may also try 

System.out.println(Arrays.toString(dob.split("\\.")));

System.out.println(dob.replace(".", ":"));

String.split takes a regular expression pattern. . matches any character in a regex. So you're basically saying "split this string, taking any character as a separator". You want:

String arr[] = dob.split("\\.");

... which is effectively a regex pattern of \., where the backslash is escaping the dot. The backslash needs to be doubled in the string literal to escape the backslash as far as the Java compiler is concerned.

Alternatively, you could use 

String arr[] = dob.split(Pattern.quote("."));

... or much better use date parsing/formatting code (e.g. SimpleDateFormat or DateTimeFormatter) to parse and format dates. That's what it's there for, after all - and it would be better to find data issues (e.g. "99.99.9999") early rather than late.

Try this

String arr[] = dob.split("\\.");

ie, you need to put the double slash to escape the dot as dot will match any character in regex. Also note that double backslash is used to create a single backslash in regex.
