Correcting Problems:

Fix the problems in the NumberList program without making any changes to the

NumberListDriver

 class.

If a user immediately enters “q” to quit, print “NaN” by making a small program correction that utilizes

double’s NaN

 value, and avoid using the

try-catch

 mechanism to catch the

int

 arithmetic exception.

Sample session:

Enter a whole number (q to quit): qMean = NaN

If the entry is not a “q,” and if it is not a legal integer, catch the exception, and in the

catch

 block use the

getClass

 method inherited from the

Object

 class to print the name of the exception class followed by the error message with the statement:

System.out.println(e.getClass() + " " + e.getMessage());

Avoid the possibility of an

ArrayIndexOutOfBoundsException

 by adding to the

while

 condition

size < numList.length,

and perform the query and entry at the end of the

while

 loop only if

size < numList.length.
