Answer 1

First off. "488.15 EUR" is a String, which cannot be parsed to any number, because it doesn't purely consist of numbers.

Secondly, you'll lose those .15 at the end if you try to convert it to an int. Use double instead. it preserves those values.

Remove the last three characters, to make suma.getText() only consist of numbers

String sumaOnlyNum = suma.getText().substring(0, suma.getText().length() - 4);

Convert it to double instead of int

double suma = Double.parseDouble(sumaOnlyNum);
