Consider the following BankAccount class. This class has a three- argument constructor method, as well as a method for computing the simple compound interest, and a couple of accessor methods for returning the bank account owners name and for returning the current balance.

/** BankAccount.java * Trivial class for creating and managing bank accounts */

public class BankAccount { // first, 3 instance variables

 private String name; private double balance; private double interestRate; //yearly rate 

 public BankAccount (String s, double openingBalance, 

 double interest) 

 { name = s; balance = openingBalance; interestRate = interest; 

}

 void compound () { balance += (interestRate / 12) * balance; } 

 public void deposit (double amount) { balance += amount; } 

 public String getName () { return name; } 

 public double getBalance () { return balance; } 

}

Suppose Geek Bank wants to store a lot of bank accounts in a two- dimensional array named geekBank such that accounts[0] stores all the accounts set up in Geek Banks first year in business, accounts[1] will store all the accounts set up in Geek Banks second year in business, and so on. As an example, consider the following declaration and initialization of geekBank:

 BankAccount [] [] geekBank = { 

 { new BankAccount(Fred, 345.00, 0.02), new BankAccount(Mary, 1234.00, 0.02), new BankAccount(Karel, 1.79, 0.025) 

}}

Note that variable geekBank contains a reference to an array. Each element of the array (e.g., geekBank[0], geekBank[1], etc.) contains a reference to an array of BankAccount objects. For example, geekBank[0] is a reference to an array containing 3 BankAccounts. Note that the above statement only initialized geekBank[0] and not the other elements of the array.

QUESTION:

Suppose that geekBank has been completely declared and initialized, not necessarily with the values shown above. In one or two simple, clear, unambiguous English sentences, what does the following loop accomplish?

 double total; int n ; for (int k = 0; k < geekBank.length; k++) 

{ total=0.0; n=0; if (geekBank[k] != null)

 { for (int j = 0; j < geekBank[k].length; j++) 

{ n++;

 total += geekBank[k][j].getBalance(); } 

 System.out.println( total / n ); } 

}

PART B

Write some Java code to print out just the name of the person who has the BankAccount with the smallest balance in all of geekBank. You may assume that all balances have different values, so that theres a single person you will have to locate.
