Question

Hey Guys i am using Google Currency Api to request for currency conversions information.
For example i use Google Currency Api

to convert 1USD to my local Currency.
The string returned is {lhs: “1 U.S. dollar”,rhs: “2 481.38958 Ugandan shillings”,error: “”,icc: true}
I need java code to extract the 2481.38958 float data type and save it in a float Variable.
Please Help.
Thanks alot.

Considering the value always will be between rhs: and a word.

String str = "{lhs: \"1 U.S. dollar\",rhs: \"2 481.38958 Ugandan shillings\",error: \"\",icc: true}";
Matcher m = Pattern.compile("rhs:\\s.*?([\\d\\s\\.]+)\\s\\w+").matcher(str);
m.find();
float value = Float.parseFloat(m.group(1).replaceAll("[^\\d\\.]", ""));
System.out.println(value);
