Answer
::   
option 1



explanation
::  
String class overriding "equlas()" method and if the value of both object is same then it returns true otherwise false.But StringBuffer class doesn't override "equals()" method. So calling equals() method on StringBuffer object always execute from "Object" class which compares the reference,if both object references are same then "Object" class equals() method returns true otherwise false.
3)   
Given:
   11. public static void main(String[] args) {
   12. String str = "null";
   13. if (str == null) {
   14. System.out.println("null");
   15. } else (str.length() == 0) {
   16. System.out.println("zero");
   17. } else {
   18. System.out.println("some");
   19. }
   20. }
What is the result?
1)
Compilation fails.
2)
some
3)
zero
4)
null
5)
An exception is thrown at runtime.

Faxing and phoning credit card information

There are many individuals who had desire to purchase online something, but expressed concern about using credit card. They chose to fax their credit card information on an internet based merchant instead of transmitting online. Faxing is often used as a acceptable alternative, but let’s talk about how safe it is? When we fax information we don’t know that who is on the receiving end-and that assume the dial number correctly.unlike form based financial transaction that is routed to one specific e-mail address, a faxed document usually winds up in hard copy format languishing in the tray of a distant fax machine. It will remain in that location accessible by anybody with access to the fax machine, until somebody comes along , removes the document and process the information in an appropriate manner- you hope. Faxing credit card information is a risky process at best, yet most people are comfortable with faxing information,so it is not perceived as being particularly insecure.many of...
