在Java中使用分隔符分割字符串

Question

I need help in splitting two email address which are seperated by a Delimiter 'AND'. I have issue when splitting, when the email address has got the characters'AND' in the email id. For eg, if the email address that needs to be split is something like the below. There are no whitespaces between the two email address.

'anandc@AND.comANDxyz@yahoo.co.in', and the delimiter is'AND' 

In the above case, there seems to be three items extracted instead of two. Can someone please help me solve this. Thanks in Advance

Answer 1

You can use " AND " as delimiter.

 String str="anandc@AND.com AND xyz@yahoo.co.in";
 String[] emailArr=str.split(" AND "); 

Or you can use following regex

  String str = "anandc@AND.com AND xyz@yahoo.co.in";
  Pattern p = Pattern.compile("[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+
                                   (\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})");
  Matcher matcher = p.matcher(str);
  while (matcher.find()) {
     System.out.println(matcher.group(0));
  }

Out put

 anandc@AND.com
 xyz@yahoo.co.in

Answer 2

Giving correct output

public class Test {
        public static void main(String args[]) {
            String text = "anandc@AND.com AND xyz@yahoo.co.in ";
            String[] splits = text.split(" AND ");
            for (int i = 0; i < splits.length; i++) {
                System.out.println("data :" + splits[i]);
            }
        }

    }

Output is

data :anandc@AND.com    
data :xyz@yahoo.co.in 

Answer 3

用这个 ：

String[] splits = text.split("\\\\s+AND\\\\s+");

Answer 4

http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#split(java.lang.String) the regular expression will be case sensitive

actually, the best is to use delimiters exression that you are sure will not be in the adress
