Khadar , i tried this code . it gives that exception
for the foll reason :
when u give a CLA(command line argument) , it will be inserted in the index 0 of the array and then will proceed to 1 ,2 ....
so as per the question , "12345" will be at s[0] . and length of that aray will be 1when u try to access s[1] , we are trying for 2nd element which is unavailable.....
Hope this answers u :-)shyamasundar

There are 3 objects created

hence there are 3 object
