Java: ReplaceAll String with another string

Question

I'm relatively new to this...

I'm trying to perform replace.all that will replace all instances of "PRICING" in a string with a numerical value which is also a variable: PRICE

SUBSCRIPTION = SUBSCRIPTION.replaceAll("PRICING",PRICE);

Below is the error i get.

Error in method invocation: Method replaceAll( java.lang.String, double ) not found in class'java.lang.String'

Thanks for your help

your code is ok!.. PRICE is String right? – DevOps85 Nov 04 '14 at 18:26 — DevOps85, Nov 04 '14 at 18:26

PRICE need to be STRING not double.

You can try this:

String price = String.valueOf(PRICE)
SUBSCRIPTION = SUBSCRIPTION.replaceAll("PRICING",price);

I see thanks! so maybe I should spend some more time learning about strings etc. i'm just having trouble constructing the price variable so that it is a string rather than a double? – user1629055 Nov 04 '14 at 18:31
@user1629055 It was a pleasure to help you :D!! you can now check the answer correct! – DevOps85 Nov 04 '14 at 18:32
@user1629055 - Leave `price` as `double` (especially, if you use it for calculations). – PM 77-1 Nov 04 '14 at 18:33

replaceAll() needs the input as,

public String replaceAll(String regex,
                String replacement)

so the replacement should be the string here , not the double as your error says,

 Error in method invocation: Method replaceAll( java.lang.String, double)

convert it into String using valueOf() method . or ,

String price= Double.toString(PRICE);

String pricing = MessageFormat.format("{0, number, currency}", PRICE);

SUBSCRIPTION = SUBSCRIPTION.replaceAll("PRICING", pricing);

Must be a string.

Here I use the default Locale with MessageFormat.

Furthermore: BigDecimal might be a better choice than the lossy double. BigDecimal must use methods like add but double is just an approximation of a real number.

The variable PRICE is of type double, and the method replaceAll requires second parameter to be a String. Just add the conversion:

SUBSCRIPTION = SUBSCRIPTION.replaceAll("PRICING",String.valueOf(PRICE));

As is indicated by the error message the replaceAll() method takes two string arguments. Try using "String.valueOf(PRICE)" to convert your double to a String representation.
