Since you have an arrangement of objects, you can perfectly store Double 's in this:

Taking your code as an example, let's use the static method valueOf of the class Double , which accepts a string as a parameter, interprets it and returns an instance of the class with the number it represents, it would be something as:

fila[4] = Double.valueOf(txtprecio.getText());
