String

Hi all,

i have a problem in string manipulation.
i want to cut the part of the string for example

ramesh(1001)
i want to cut the number 1001
how to do this. please help me on this.....

You are not very clear in what you actually want to do, give some more information about the string and what you want to cut from it.

hi,

"ramesh(1001)" is the string and i want to cut only "1001" from it.
i hope this is clear to u

In the java.lang.String class there is a method substring( int beginIndex, int endIndex ). You can use this method for your string :String myString = "ramesh(1001)".substring( 7, 11).

Then the String myString contains "1001"

Hope this helps,

Hannes

hi,

but i am reading the string from another page. so the string value changes every time.

You say that the string value changes every time, but is there always a substring "1001" present in the string?

You can use regular expressions:

Code:

---

String yourNewString= yourString.replaceAll("\\d+", "");
// result will be: "ramesh()"

hi,
i want only the part within the bracket that is the substring 1001. the string changes whenever i read from another page.

That's easy too:

Code:

---

String yourNewString= yourString.replaceAll("[^\\d]+", "");
// result will be: "1001"

The regular expression matches one or more non-digits; they are replaced by exactly nothing "". Read the API documentation of the Pattern class for a short introduction to regular expressions.

Here it is; you're not telling me that until now you have been programming in Java without this documentation are you?
