How do I convert data to whole string when I have data using Regex

advertisements

I am getting data as string and would like to add in Array. But Data I am getting is as String and looking to store as Integer.

Code :

             public static List<Integer> PriceData = new ArrayList<Integer>();
             public static String FinalPrice;

                       Pattern Pricepattern = Pattern.compile("Price\\s*:\\s*(\\S*)");
                       Matcher Pricematcher = Pricepattern.matcher(Content);
                       if(Pricematcher.find()) {  //we've found a match
                           FinalPrice = Pricematcher.group(1);
                       }

                      try
                      {

                      PriceData.add(Integer.parseInt(FinalPrice));

                      }
                      catch(NumberFormatException N)

                      {

                          System.out.println("Invalid Price Data");

                      }

Output :

FinalPrice : "$10.35"

PriceData : It always goes to exception. Here I want to store 10.35.

If I declare Finalprice as Integer then also have same problem.


You can fix your regex to catch price only and also you should parse to float or double. Integer has no floating point so it throws exception. Also - NumberFormatException is runtime exception so you don't need try/catch here. Here's example:

public static void main (String[] args){
        String finalPrice = null;
        String price = "Price : \"$10.35\"";
        String regex = "Price\\s:\\s\"\\$(\\d+.\\d+)\"";
        Pattern Pricepattern = Pattern.compile(regex);
        Matcher Pricematcher = Pricepattern.matcher(price);
        if(Pricematcher.find()) {  //we've found a match
            finalPrice = Pricematcher.group(1);
        }
        float parsedPrice = Float.parseFloat(finalPrice);
        System.out.println(parsedPrice);
    }
