Is this possible?

[harry]

I want to achieve some sort of parameter substitution, whereby one string is
inserted in to a specifc position within another string - the same as with a
resources file i.e {0}

So if -
st1 = "There is an Error in {0} - stop what you are doing!"
&
str2 = "Project Search"

Is there a simple way of producing -

str3 = "There is an Error in 'Project Search' - stop what you are
doing!"

thanks

You would have to use curly braces wouldn't you!


st1.replaceFirst("\\{0\\}{1}", str2);

I think

see java.util.regex.Pattern docs

Thanks for the fast response Mike, works just as I wanted! (sorry about the
curly braces, copied the idea from my resources file!)

It especially likes the curly braces.

st1.replaceFirst("\\{0\\}{1}", str2);

there is no need for the regex version. Just use vanilla replace.
