public static void main (String[] args)
{
Stack<Integer> mat=new Stack<Integer>();
mat.add(1);
mat.add(3);
mat.add(6);
System.out.println(mat);
Object [] a=mat.toArray();
for(int i=0;i<a.length;i++)
System.out.println(a[i]);
}
}

An integer type stack st is created;
1,3 and 6 are added to the stack.
printing the contents of the stack.

Powerpoint has a large number of animation effects, of which "Appear" is the simplest and most common one, followed by "Fade". So I guess you're looking of one of these.
Answer:
The answer is B.
Explanation:
Radio Frequency Identification (RFID) is a technology that uses radio waves to secure objects, pair devices, tag them etc. and it is made up of a transmitter which emits radio waves and a receiver.
The example given in the question where Jamie listens to the communication between the RFID tag and the devide of the user and copies the information to later use it to gain access to the vehicle is an example of a replay attack.
Also called "eavesdropping & replay", the first part is the listening to the conversation to steal the data and the replay part is where he uses the information to gain access.
I hope this answer helps.
