}
Consider the following program written in Java and answer the question:
1. import java.util.*;
2. class Arraylist
3. {
4. public static void main(String args[])
5. {
6. ArrayList obj = new ArrayList();
7. obj.add("B");
8. obj.add("C");
9. obj.add("C");
10. obj.add("D");
11. obj.remove(2);
12. System.out.println(obj.get(1));
13. }
14. }
What would be the output of the statement when the program is executed?

Where's the Biggest One?
by CodeChum Admin
We've already tried comparing 3 numbers to see the largest among all, so let's try a more complicated mission where we locate the position of the largest among 5 numbers. There are only 4 possible cases for this mission:
- if the largest digit is the first digit, print "Leftmost"
- if the largest digit is the third digit, print "Middle"
- if the largest digit is the last digit, print "Rightmost"
- if none of the above is correct, print "Unknown"
Now, show me how far you've understood your lessons!
Input
A line containing a five-digit integer.
1·4·6·3·2
Output
A line containing a string.
Middle
Java practical 1
It has been realized that hackers have started hacking and changing the account detains of some banks, to stop this practice, you have been tasked to create a class called Abaaneke, your class should contain three private variables (deposit, oldBalance, newBalace) all of type float and a variable of type String (name of the account holder)
Your class should also have a method that takes three arguments – name of account holder, amount deposited and old balance. The method should add the deposit to the oldBalance and call it new balance.
Using the right setters and getters, initialize the private variables and call the method to display the following
a. Account holders name
