d. File TestAccounts1.java contains a simple program that creates the specified number of bank accounts then uses the getNumAccounts method to find how many accounts were created. Save it to your directory, then use it to test your modified Account dass. 2. Add a method void close() to your Account class. This method should close the current account by appending "CLOSED" to the account name and setting the balance to 0. (The account number should remain unchanged.) Also decrement the total number of accounts. 3. Add a static method Account consolidate(Account acct1, Account acct2) to your Account dass that creates a new account whose balance is the sum of the balances in acct1 and acct2 and doses acct 1 and acct2. The new account should be returned. Two important rules of consolidation: Only accounts with the same name can be consolidated. The new account gets the name on the old accounts but a new account number. Two accounts with the same number cannot be consolidated. Otherwise this would be an easy way to double your money! Check these conditions before creating the new account. If either condition fails, do not create the new account or close the old ones; print a useful message and return null. 4. Write a test program that prompts for and reads in three names and creates an account with an initial balance of $ 100 for each. Print the three accounts, then dose the first account and try to consolidate the second and third into a new account. Now print the accounts again, induding the consolidated one if it was created. // TestAccounts1 // A simple program to test the numAccts method of the // Account class. import java . util .
