Java set values after if else loop in one line

How do I achieve setting the value inside if else in one line?

String amount = myJSON.optString("cValue")
    double cValue = (amount != null && !amount.isEmpty()) ? Double.parseDouble(amount) : 0;
    if (cValue > 0) {
       mySavings.setCouponValue(cValue);
    } else {
      mySavings.setCouponValue(0.0);
    }
