Yes I would agree, it makes the most sense that she backspaced to delete the - sign and replaced it with the = sign since they sit right next to each other on the keyboard, and one could easily type the - instead of the =.
The poor Youtube resolution would explain why I thought it was an = sign rather than a - sign that she deleted.
But what I still don't understand is why I can't see anything she types immediately after deleting the - sign, but some of you folks here do?
A little more detective work might help us.
On the (source) page Netbeans Introduction to GUI Building page that she refers to throughout the video
Netbeans
when you scroll down you see :
num1 = Float.parseFloat(jTextField1.getText());
num2 = Float.parseFloat(jTextField2.getText());
// Now we can perform the addition.
result = num1+num2;
however in the video I can only see the first = sign.
The other two are missing on my screen.
Do you see all three in the video?
