Matching regex in step definition

I have a Given statement in my feature file

Given I have $100.25 in my bank account

The following step definition is not picking up the decimal fraction

 @Given("I have \\$\\d+(\\.\\d+) in my bank account")
    public void given_money_in_bank_Account(double money){
      //This returns money as .25
    }

I am sure my regex is correct here. How can I get 100.25 passed as argument?

Solution

  • You have a misplaced group. It should be I have \\$(\\d+\\.\\d+) in my bank account.

    But parsing floating point numbers with regex is not recommended. You have dozens of representation to represent a floating point number and the above regex only caters to a few.
