@MrDarkzone93 bit late but here is the script for plusminus. you couldnt see it in the video but i kinda made it up as i went and it works.. :)

plusminus=(Double.parseDouble(­String.valueOf(display.getText­()))); plusminus=plusminus*(-1);

display.setText(String.valueOf­(plusminus));

@pohasche Oh I see, this might help. Thank you!

[pohasche]

@ShyneBrady no, you needn't. In calculate function(equalsActionPerformed in our case) you should write firstDouble=totalDouble instead of firstDouble=0.

[ShyneBrady]

I didn't try this but what if you got something like: 1+2+3?

So you need a thirdDouble and so on???

[MrDarkzone93]

what is the code of plusminus?
