how to get substring between two delimeters in java

Question

I want to get substring from starting line third comma(delimeter) and from ending line second comma(delimeter).

eg:- input:

"8884052344,89,\N,11805143\,3\,6112555\,6538937\,5839176\,5420860\,6590106\,2646753,0,2015-09-29 10:52:29"

Output:

11805143\,3\,6112555\,6538937\,5839176\,5420860\,6590106\,2646753

Note: From the starting line third comma and from ending line second comma substring may increase the size.Please help me.

Thanks.....

So what have you tried so far? Are you expecting us to write the code for you? Try some code and then if you have a problem, come back and ask it here. — STaefi, May 25 '16 at 11:09

You can cut the string by the "," and than make a new string, read this How do I use a delimiter in Java Scanner?

Will the String always have more than 5 commas ? I have assumed that it will , We can solve it in two ways.

First approach

I have used indexOf to determine the index of third occurrence of "," and lastIndexOf to determine the second last occurrence of ",".

String ex= "8884052344,89,jhgN,11805143,3,6112555,6538937,5839176,5420860,6590106,2646753,0,2015-09-29 10:52:29";
int beginningIndex= ex.indexOf(',',(ex.indexOf(',',ex.indexOf(',')))+1)+1;
int lastIndex= ex.lastIndexOf(',',ex.lastIndexOf(',')-1);
String desiredResult=ex.substring(beginningIndex,lastIndex);

Other approach .

you can just split the String , you will get an array . create a StringBuffer and append the String from the index 3 till the second last index ( array length - 3 ) .
