How to convert double to object?

Question

I am writing part of my program which read data from a txt file.

I have problem when I want to set value of JSpinner by setValue(object).

My data is double so I need to convert it to object, but how?

LoadData open = new LoadData();
data.setFz(open.giveAwayData());
spinner_1.setValue(data.getFz()); // Fz is double

Answer 1

Try casting it to Double (with capital):

spinner_1.setValue((Double) data.getFz());
