how to extract substring

[Petterson Mikael]

Hi,

I have the following string (read from a file).

} lrsstuv;

I need to extract the lrsstuv part. The bracket will always be there.
The number of spaces after the bracket varies. And at last the ';' is
always after there after the name. Any hints on how to do this?

I am using jdk 1.4

cheers,

String s = "} lrsstuv;";
String result = s.substring(1, s.length()-1).trim();

try to match it against a regular expression? Try something like

}\s*(\w+);

(no guarantee for escape characters...)
Look into the documentation for java.util.regex.Pattern.

If you are sure that the "}" and ";" are really there, you can also use
s.substring(1, s.length()-2).trim() to remove "}" and ";" and then remove the
blanks. That could be easier.

Last works like a charm ;-)

No, it does not. It also removes the last character, in your case the 'v'.
It should be '-1' instead of '-2'.

You are right, sorry. Second argument is endIndex, not length.

You could use a regex split with ; and space as split chars, or even }
too.

Yeah I know but that part was so simple that I could change it myself.
