Converting sed regex to Java regex

Question

I am new to reguler expressions.I have to write a regex which will do some replacements
If the input string is something like test:[email protected];value=abcd
when I apply the regex on it,this string should be changed to test:[email protected];value=replacedABC
I am trying to replace test.com and abcd with the values i have supplied...
The regex I have come up with is in sed
s/\(^.*@\)\(.*\)$/\1replaceTest.com;value=replacedABC/i
Now I am trying to get the regex in Java,I would think it will be something like (^.*@\)(.*\)$\1replaceTest.com;value=replacedABC
But not sure How i can test this.Any idea on how to make sure my java regex is valid and does the required replacements?

Yep.Agreed.
Since that these replacements should be done in a single regex.Note that the sed replacement I posted is really made of two replacements! Just like your Java solution would.
I think once we send this regex to the third party,they will haev to use either sed or perl(will perl do this replacements,not sure though) to get the output.
Since we are not sure what tool/software the third party is going to use,I was trying to see how i can really test this.Then I read about sed and this regex as is didn't work,so,I had to put all the sed required / and then the regex had become like s/\(^.*@\)\(.*\)$"/1replaceTest.com;value=replacedabcd/iAgain: AFAIK that does not work. I tried it like this:
{code}$ echo test:[email protected];value=abcd | sed 's/\(^.*@\)\(.*\)$"/1replaceTest.com;value=replacedabcd/i'and the following is returned:test:[email protected] that we will have to send the java regex to the third party,I was trying to see how i can convert this sed regex to java.If I am right,with jave regex,we won;t be able to all the finds and replacements in a single regex..right?...If this is true,this will leave me a question of whether I need to send the sed regex to the thrid party or If I send java regex,they have to convert that to either sed or perl regex.
One more question,can we do thse replacement in perrl also,if so,what will the equivalent regex for this in perl?
I can't understand what you are talking about. The large amount of spelling errors also doesn't help to make it clearer.
Good luck though.
