Thread: If-Else Statement help

Hi,

i will try to help you out a bit

The method "public static void main(String[] args)" is basically only needed as entry point for standard java programs, if your applet is run from a browser you wont need that function.

And about the if,i would better write it in a way like

if ((answer.equalsIgnoreCase("y") || (answer.equalsIgnoreCase("yes")) {
....

this ensures String comparison is used, and if the user types Y or YES it will be also valid.

And to use best practises with this you want to turn it around as well

if (("y".equalsIgnoreCase(answer) || ("yes".equalsIgnoreCase(answer)) {

// Json

I tried your suggestions but it says answer cannot be resolved--what does that mean? Also, I'm running this program from eclipse.

Okay everything is working as far as I can tell, BUT...when the program loads it won't allow me to add input using the keyboard. Is it the braces? Or is there some coding wrong?

Well i guess it is cause you can't use "System.in" for applets

I have found this link explaining how to get key input in applets:
Applet Tutorial: Keyboard Input

I hope you can use it for JApplet too
