How to parse a string with "|" and empty strings

[Rajani Gummadi]

Hi All,

I'm trying to parse a String like A|B|C|D||||| as follows

    
     String str  = "A|B|C|D|||";
     String[] tokens = str.split("\\|");
     for(int i=0;i<tokens.length;i++){
          System.out.println("Token = "+tokens[i]);
    }

My expectation is as follows

Token = A
Token = B
Token = C
Token = D
Token =
Token =


But I get only first 4, obviously the last 2 are not considered or ignored... I knew that my regular expression is wrong, but could not figure out the solution on how to have the emply strings surrounded by "|" is also retrieved..

Can some body help me in this ?

Use the form of "split" that takes a second int parameter; pass Integer.MAX_VALUE as the argument when you call it. The empty substrings will be returned.
