How to get a list of multiple emails from a string by using split in Java? -


i'm facing issue hours :( . have string contains bunch of emails in it:

" email1@gmail.com , 'email2@gmail.com,email3@gmail.com, email4@gmail.com' , 'email5@gmail.com ,email6@gmail.com' "

so i'm trying extract each email each substring , end array contains email:

example:

string[] myarray = {email1@gmail.com , email2@gmail.com, email3@gmail.com, email4@gmail.com, email5@gmail.com};

here's code:

string str = "email1@gmail.com , 'email2@gmail.com,email3@gmail.com, email4@gmail.com' , 'email5@gmail.com ,email6@gmail.com'";      string[] newarray = str.split(",");      for(int = 0 ; < newarray.length; i++)          {         if(newarray[i].contains(","))           {             newarray = newarray[i].split(",");          }         }

keep in mind substring may have multiple emails in it. thank help!

you can use pattern matching , regex, simple email follows : \w+@\w+.com : multiplewordcharacter@multiplewordcharacter.com

public static void main(string[] args) {     string str = "email1@gmail.com,'email2@gmail.com,email3@gmail.com, email4@gmail.com'" +             ", 'email5@gmail.com ,email6@gmail.com'";      matcher m = pattern.compile("\\w+@\\w+.com").matcher(str);     list<string> emailslist = new arraylist<>();      while (m.find()){         emailslist.add(m.group());     }      string[]emailsarray = emailslist.toarray(new string[0]);  // if need array     system.out.println(arrays.tostring(emailsarray)); }

i used list @ first because it's easy add element dunamiclly, can't array, @ the, end still can use array code wrote

and print : 

[email1@gmail.com, email2@gmail.com, email3@gmail.com, email4@gmail.com, email5@gmail.com, email6@gmail.com]
