For example: Class A created with method m1() and its object created in various other files. later m1() changed to m2() and class has added some more public variable. Now question is how does object created in other files came to know about this change happened in its class. Is Object Listener linked to this question???

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  :-)
