Dividing a string
Please support our Java advertiser: Programming Forums - DaniWeb Sister Site

I have a string that looks for example like this:
"aabbccddeeffgg"
I want to retreive the "ee" or the "cc" value from that string. How can I do that ? The tokenizer is not what I am looking for. I'm looking for the function that allows you to specify that you want the part of the string starting at letter 4 and ending at letter 7.
Please help ;')

Look at the String documentation at:
http://java.sun.com/j2se/1.4.2/docs/api/index.html
specifically at the substring method

you can also use the indexOf method of the string class ... see the String APIs for more reference.
Thank I used to them ,but I'm from to VietNam so I read English verry bad
can you give me some example.
Thank verry much!
can you give me some example.
Thank verry much!
Rentro,
You it it right on. Java actually has a substring function.
See the jdocs for details.

String s = "aabbccddeeffgg";
String s1 = s.substring(4,7);
System.out.println(s1);
it will give the output ccd.
but if it's "ee" you want as result:
int pos = firstString.indexOf("ee");
System.out.println(firstString.substring(pos, pos+2));
int pos = firstString.indexOf("ee");
System.out.println(firstString.substring(pos, pos+2));

String s=firstString.substring(8,10);
System.out.println(s);
it will give the output "ee"
but if you would want any arbitary substring then your opinion is correct.
But then if you want an arbitary substring of three or more characters then it would not work, and you would be writing firstString.substring(pos,pos+3) or String.substring(pos,pos+4).
Anyway, thanks for sending me your opinion about this.
