Initialization Prompt

Is there any way I can have some sort of pop up window before my void setup{} and void draw{} run?

The program I have built basically takes in two arrays, numbers and operators, and displays the equation. Right now, I need to hard-code the numbers and operators arrays in void setup{}. I would like to have a popup window before void setup{} runs that asks the user to type in an equation, and then I can parse this text and use it to fill up the numbers and operators arrays upon setup.

Is there some way to write a new Processing sketch for this prompt and parsing, and have it feed outputs into my equation sketch? Or should I empty out the void setup{} section, move it to void draw{} with a "setup" flag? Then I can use the void setup{} section to run the prompt?

Thanks for your help. I apologize if this is a silly/overdiscussed topic.

boolean isPrompt=true;
void setup(){
// Whatever your setup does, except defining what you need the prompted data for.
}
void draw(){
if( isPrompt ){
background(0);
fill(255);
text( "Please type in some number, then hit enter.", 20, 20 );
} else {
// Whatever your normal draw would do.
}
}
void keyPressed(){
if( isPrompt ){
// Code here to add the typed digit to your number.
// Code here to detect the enter press
if( key == ENTER || key== RETURN ){
value = enteredValue;
// Generate whatever data you would normally have done in setup here.
isPrompt = false;
}
} else {
// Whatever your normal keyPressed() function was, if it existed at all.
}
}
