Extracting only text form String in Java

Question

I have got string like str = Adobe Flash Player 11.4.402.287 (11.3 MB), I need to extract only Adobe Flash Player as the output. Pls suggest..

I tried using Regex like :

String str = "Adobe Flash Player 11.4.402.287 (11.3 MB)";
        Pattern p = Pattern.compile("^[a-zA-Z]+([0-9]+).*");
        Matcher m = p.matcher(str);

        if (m.find()) {
            System.out.println(m.group(1));
        }

Use `"[\\p{L}\\s]+"`. Now let's wait and see if someone makes this suggestion into his own answer :) — Marko Topolnik, Oct 30 '12 at 08:54
@BuiAkinori. How exactly would that return `Adobe Flash Player`? — Rohit Jain, Oct 30 '12 at 08:55
@BuiAkinori: How about this ?? String str = "Adobe Flash Player" ;) — kidd0, Oct 30 '12 at 09:00
@BuiAkinori: No offense buddy. I probably thought the question was extracting some string from a [string] [number] format when the length was unknown. — kidd0, Oct 30 '12 at 09:03
@BuiAkinori. That would still not compile. It should be `substring` and not `Substring`. — Rohit Jain, Oct 30 '12 at 09:05

Try this:

    String str = "Adobe Flash Player 11.4.402.287 (11.3 MB)";
    Pattern p = Pattern.compile("^([a-zA-Z ]+)([0-9]+).*");
    Matcher m = p.matcher(str);

    if (m.find()) {
        System.out.println(m.group(1));
    }

There are two problems in your try:

Grouping is done using (), you did not define a group for the text you actually wanted
You need to add a space to get more than one word.

You can use regex:

String str = "Adobe Flash Player 11.4.402.287 (11.3 MB)";
String [] strs = str.split("([ |0-9|.|(.*MB)]*) [ |0-9|.|(.*MB)]*");
for (String strng : strs) {
    System.out.println(strng.trim());
}

Horrible way to do simple stuff. I'll die figuring out, why someone would split a string like that. – Rohit Jain Oct 30 '12 at 09:01
Why on Earth do you want to match the exact character sequence "0-9"?? – Marko Topolnik Oct 30 '12 at 09:04
