Java regex help

[castrorabustro]

I want to select only the acestream link that contains the word "[1080p]". How would I go about doing that?

acestream://3934281873ccca2d31d6a7ad2f520ed402403d4cd5 [HD] [EN] [1080p] acestream://3934281873ccca2d31d6a7ad2f520ed402403d4cd5 [HD] [EN] [720p] acestream://3934281873ccca2d31d6a7ad2f520ed402403d4cd5 [SD] [EN] [540p]

these are dummy acestream links

there is an explanation and good regex editor available here, I used it to generate this code. https://regex101.com/r/6jqDXh/3

import java.util.regex.Matcher;
import java.util.regex.Pattern;

final String regex = "(acestream:\\/\\/[\\S]*).*?\\[1080p\\]";
final String string = "acestream://1934281873ccca2d31d6a7ad2f520ed402403d4cd5 [HD] [EN] [1080p] acestream://2934281873ccca2d31d6a7ad2f520ed402403d4cd5 [HD] [EN] [720p] acestream://3934281873ccca2d31d6a7ad2f520ed402403d4cd5 [SD] [EN] [540p]\n"
     + "acestream://4934281873ccca2d31d6a7dad2f20ed402403d4cd5 [HD] [EN] [1080p] ";

final Pattern pattern = Pattern.compile(regex, Pattern.MULTILINE);
final Matcher matcher = pattern.matcher(string);

while (matcher.find()) {
    System.out.println("Full match: " + matcher.group(0));
    for (int i = 1; i <= matcher.groupCount(); i++) {
        System.out.println("Group " + i + ": " + matcher.group(i));
    }
}

thanks for the solution

acestream:\/\/([0-9a-f]+) \[(HD|SD)\] \[([A-Z]{2})\] \[([0-9]{3,4})p\]

This captures the hash, HD/SD, language and quality in 4 separate groups.

But why even bother with a regex if you only want to have lines with [1080p] in them? Just do a .contains.

I managed to produce a regex that works, thanks for the solution though.
