Posted 2021-05-07

public static boolean isMyChannelId(Long employeeId, String channelId) { 
    assert(employeeId != null);

    Matcher pattern = Pattern
    		.compile("user_(?<user1>[0-9]+)_user_(?<user2>[0-9]+)")
    		.matcher(channelId);

    if (pattern.matches()) {
    	long user1 = Long.parseLong(pattern.group("user1"));
    	long user2 = Long.parseLong(pattern.group("user2"));
    	return user1 < user2 && (employeeId == user1 || employeeId == user2);
    }

    return false;
}
