/* First example of an exception
If something may go wrong, you can often test for that ahead of time -
but that could be a lot of code and you would need to be aware of all
possible errors. It's far better to catch exceptions, which are much
more "fail safe"
public class neston
public static void main(String args)
System.out.println("Short pack of 20 cards");
("And a set of Cluedo suspect cards!");
card_7  play = new card_7  ;
int cardcount = 0;
for (int k=0;k<6;k++)
play[cardcount++] = new suspect_card_7(k);
for (int k=33;k<53;k++)
play[cardcount++] = new playing_card_7(k);
catch (ArrayIndexOutOfBoundsException e)
("Hand full. Excess cards dropped");
// And print out cards!
for (int k=0;k<cardcount;k++)
/* Sample output:
