Regex Replacing issue understanding

I'm trying to program a replacement logic for invalid phone numbers, which I provide with a Map
I read through a few Regex expressions threads, but I don't know if this actually is possible.
Example:
Input phone number: +410712345678
regex I'm trying to use:
"^\\+(?:[0-9] ?){6,14}[0-9]$"
number after regex and filtering should be: +41712345678. So actually removing the first Instance of 0.
Second example:
input phone number: +41(071)2345678
regex I'm trying to use:
"^\\+(?:[0-9] ?)\\({0,3}\\){3,11}[0-9]$"
number after regex and filtering should be: +41712345678. So actually removing the First Instance of 0 and also the braces.
I'm trying to user some kind of pattern to automatically remove those invalid pieces from those phone numbers. The numbers need to be formatted that way to work with my VOIP application.
Is there any way to create a filter pattern like that with regex?

Seems like you should only apply that rule for Switzerland phone number, i.e. for +41 numbers, because simply removing the first 0 from any international number is wrong.
So, ph = ph.replaceFirst("^(\\+41)\\(?0?([0-9]{2})\\)?", "$1$2").
See regex101 for how it works.

Thank you for your answer.
I applied the Regex to my TestImport with the following code:
//...
log.debug("Applying Regex :" + SearchString + " with Replace: " + ReplaceString);
log.debug("Applying Regex for Number:" + Person.get(EPerson.Rufnummer));
Person.put(EPerson.Rufnummer, Person.get(EPerson.Rufnummer).replaceFirst(SearchString, ReplaceString));
log.debug("New Number is:" +Person.get(EPerson.Rufnummer));
log.debug("Applying Regex for Number:" + Person.get(EPerson.RufnummerMobil));
Person.put(EPerson.RufnummerMobil, Person.get(EPerson.RufnummerMobil).replaceFirst(SearchString, ReplaceString));
log.debug("New Number is:" +Person.get(EPerson.RufnummerMobil));
//...
DEBUG [AddressbookFactory] Applying Numberfilter to: {Vorname=Testinator, Nachname=Test, Rufnummer=+410717271818, RufnummerMobil=, RufnummerPrivat=+41(071)7271818, Fax=, Strasse=, PLZ=, Stadt=, Bundesland=, Email=, Firma=, URL=}

And it worked!
Thank you so much for your Quick Response!
I marked your answer as useful, but trough my "newbie" Reputation it does not indicate it.
This Question is resolved.

Best way to use/practice of using parentheses in java

While working on Sonar static code analyzer I found some confusing (may be only to me) statement by Sonar on using parentheses.
Below are the few code snippets where Sonar says remove useless parentheses:
line>1 String auth = "Basic "+ com.somepackge.someMethod(((String) (parent.proxyUsername+ ":" + parent.proxyPassword)));
line>2 return rawtime.length() > 3 ? (rawtime.substring(0, rawtime.length() - 2) + rawtime.substring(rawtime.length() - 2, rawtime.length()).toLowerCase()) : rawtime;
though I have replaced above lines with below one to keep Sonar calm :) :
Line>3 String auth = "Basic "+ com.somepackge.someMethod((String) (parent.proxyUsername+ ":" + parent.proxyPassword));
Line>4 return rawtime.length() > 3 ? rawtime.substring(0, rawtime.length() - 2) + rawtime.substring(rawtime.length() - 2, rawtime.length()).toLowerCase() : rawtime;
So the reason for discussing this question is:
Actually using braces/parentheses are way to reduce the confusion so why to remove those parentheses.
What is best way to use parentheses while writing any complex statement in java.
See the line>1 and Line>4 here I think
(String) (parent.proxyUsername+ ":" + parent.proxyPassword)
this part of code should have the braces to avoid confusions but what Sonar expect is something like:
(String) parent.proxyUsername+ ":" + parent.proxyPassword
Any suggestion would be a great help. I got some links regarding this question but those were not much helpful.

First snippet
String auth = "Basic "+ someMethod(((String) (parent.proxyUsername+ ":" + parent.proxyPassword)));
You could rewrite it as:
String auth = "Basic "+ someMethod(parent.proxyUsername+ ":" + parent.proxyPassword);
because the string concatenation operator already does a string conversion. Unless you want a ClassCastException thrown when proxyUsername or proxyPassword are not Strings?
Second snippet
return rawtime.length() > 3 ? (rawtime.substring(0, rawtime.length() - 2) + rawtime.substring(rawtime.length() - 2, rawtime.length()).toLowerCase()) : rawtime;
The parenthesis is indeed unnecessary but the statement is quite unreadable. If you want to keep using the ternary operator I would suggest splitting the statement across lines:
return rawtime.length() > 3
? rawtime.substring(0, rawtime.length() - 2) + rawtime.substring(rawtime.length() - 2, rawtime.length()).toLowerCase()
: rawtime;
or you could revert the condition:
return rawtime.length() <= 3 ? rawtime :
rawtime.substring(0, rawtime.length() - 2) + rawtime.substring(rawtime.length() - 2, rawtime.length()).toLowerCase();

Line 1 has redundant parentheses, but Line 2's parentheses add clarity to the ternary statement.
Whether or not the extra parenthesis in 2 are useful is up for debate - but there's no reason not to remove the redundant ones in 1.
Generally it's best to use extra parenthesis to convey your intent about what the code should do, or to remove ambiguity in the order that things occur.

There is a semantic difference between these two versions:
(String) (parent.proxyUsername+ ":" + parent.proxyPassword)
(String) parent.proxyUsername+ ":" + parent.proxyPassword
In the first, the second set of () already evaluates to a String, implicitly calling parent.proxyUsername.toString() to convert proxyUsername to a String. So the cast is redundant and should be removed IMHO. The second version casts parent.proxyUsername to String, and will throw an exception is it hasn’t got runtime type String (only if it is declared a String is the cast redundant).
I agree that line 2 and 4 are complicated to read no matter if they have the redundant braces or not. Rewrite if you want clarity. That said, redundant braces are sometimes good for clarity IMHO, I do use them occasionally.

the best way is to put your class that you're casting to in a parentheses then the whole part to be converted in another parentheses, then include this whole code in a container parentheses, your code should look like this e.g ((String)(x+y)).
I hope that was helpful, thanks.

String to Int with a + sign

I'm parsing stock data and trying to put it into a SQL database. All of the info from the parse is retrieved as a string. I am using the Integer.parseInt() method to try and convert the strings to integers for some of the info. The issue I am having is with the Change data. When it is a positive change the number has a "+" sign in front of it and I am getting an error:
Exception in thread "main" java.lang.NumberFormatException: For input string: "+0.14" //
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65) //
at java.lang.Integer.parseInt(Integer.java:492) //
at java.lang.Integer.parseInt(Integer.java:527) //
at getStockData.main(getStockData.java:91)" (the //s are to signify end lines, having issues with formatting)
My Output is:
Ticker ID: MSFT: Change - [+0.14]
int Change = Integer.parseInt(di.getTextContent());
I don't really know how to get around this error at the moment, and haven't found anything similar to this after googling / searching stackoverflow.

The issue is 0.14 is not a valid int. Try using Double.parseDouble(String) to parse the double value. Like
double v = Double.parseDouble("+0.14");
System.out.println(v);
Output is
0.14

How to claculate string column Sum in jasperReport

I need to retrieve sum of a String column so i wrote this :
<variable name="totalQt" class="java.lang.Integer" calculation="Sum">
<variableExpression>
<![CDATA[Integer.parseInt($F{QTARTBP}.replaceAll(" ", ""))]]>
</variableExpression>
</variable>
But i'm getting this error :
....
Caused by: java.lang.NumberFormatException: For input string: ""
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
at java.lang.Integer.parseInt(Integer.java:504)

at net.sf.jasperreports.engine.fill.JREvaluator.evaluateEstimated(JREvaluator.java:254)
So there are empty string , so how to use zero in that case , i wrote thiw but it's wrong
:
<variableExpression>
<![CDATA[$F{QTARTBP}.equals("") ? 0 : Integer.parseInt($F{QTARTBP}.replaceAll(" ", ""))]]>
</variableExpression>
Any idea will be appreciated

It would be useful to see what input data you are using, but despite that, it's clear that your code will fail if the value of $F{QTARTBP} is a single space (" "). You could try the following expression instead, which will include the single space in your empty string check and will return 0 instead:
$F{QTARTBP}.replaceAll(" ", "").equals("") ? 0 : Integer.parseInt($F{QTARTBP}.replaceAll(" ", ""))
You should be aware that this is will still fail if any of your input strings cannot be interpreted as an integer.

Jasper are not to calculate - you should generate String in your java-code. And calculate what you need in java too.
Upd. This answer is incorrect. I learned JR more deeper and understand it.

String formatting problem Java

im trying to format this string into a fixed column style but cant get it to work, heres my code, whats up?
System.out.format("%32s%10n%32s%10n%32s%10n", "Voter: " + e.voteNo + "Candidate: " + vote + "Booth: " + boothId);
All variables are integers,
I want the output to be like
Voter: 1 Candidate: 0 Booth: 1
Thanks

Please stop trying to program by accident. Your code looks like the glued-together parts of 3 different approaches to solving the issue. Try to read the documentation on the topic (JavaDoc is your friend!) and apply what you learned instead.
String result = String.format("Voter: %-10d Candidate: %-10d Booth: %-10d", e.voteNo, vote, boothId);
System.out.println(result);
For more information on String.format check its JavaDoc.
Edit: apparently I didn't get the memo that there's actually a PrintStream.format, so you can actually write it like this:
System.out.format("Voter: %-10d Candidate: %-10d Booth: %-10d", e.voteNo, vote, boothId);
