Question

i get a big string from a web page and its like this

"07:10Ο ΑΣΔΦΑΣΔΦ07:30ΑΣΔΦΑΣΔΦ10:15ΝΑΣΔΦΑΣΔΦ"

and i want every time i find time like this “17:50” or “07:30” to get a new line before the time! so i will have

07:10   ΑΣΔΦΑΣΔΦ
07:30   ΑΣΔΦΑΣΔΦ
10:15   ΝΑΣΔΦΑΣΔΦ

etc…

but here is my problem i tried to copmare the letters with this

StringBuilder builder = new StringBuilder(text);
for (int i = 0; i < text.length(); i++) {
     if(Character.isDigit(text.charAt(i))){
            builder.insert(i, "\n");
     }
}

but inside my text i have Greek letters so the isDigit returns 1 when it gets some Greek letters. Anyone has any idea how to solve this?

To provide some initial help, the builder.insert() line isn’t doing what you probably want:

StringBuilder builder = new StringBuilder(text);
for (int i = 0; i < text.length(); i++) {
     if(Character.isDigit(text.charAt(i))){
            builder.insert(i, "\n"); // questionable
     }
}

Do you really want `\n1\n2:\n4\n5″ for the string “12:45”?

You might just want to match "\\d\\d[:.]\\d\\d" and prepend “\n” postpend ” ” on each match, but I can’t be certain I understand your problem.

Specifically, I just tried:

String str = "07:10Ο Σκούμπι Ντου & ο κολλητός του07:30Πρωϊνή μελέτη10:15Νηστικοί πράκτορες11:15Σαρίτα, είσαι η ζωή μου12:50Οι ειδήσεις του Star13:45Made in Star15:45Μίλα17:45Ειδήσεις17:50Φώτης - Μαρία live19:45Οι ειδήσεις του Star21:00Ο Χαρί Πότερ και ο ημίαιμος πρίγκιψ00:15Σχολή για απατεώνες01:15Supernatural02:15Gypsy woman02:30Τα πλοκάμια του τρόμου03:45Ραπ πάρτι04:30The Dead zone";
return str.replaceAll("(\\d\\d[:.]\\d\\d)", "\n$1 ");

Does this work the way you want? My terminal doesn’t seem to support these characters very well, so I may have a locale encoding issue.
