`Double.parseDouble(String)` – MadProgrammer Aug 07 '15 at 04:39

You should also consider using a `NumberFormat` – MadProgrammer Aug 07 '15 at 04:43

You can use the methods: Double.parseDouble(String number) or Integer.parseInt(String number) to convert the number you're receiving. Both of them throws NumberFormatException so make sure to catch and handle the exception properly.
