Hi, everyone

I'm learning to write Java Card Applet.

Can anyone help me?

There is a special function for exception handling in class "ISOException":
public static void throwIt(short sw)
you could use it.
Firstly, you need to import the class "ISOException" in your Applet by using the command below:
"import javacard.framework.ISOException;"
next step, call the function when you need,such as:
if(condition == false)

Hope it helps you.
