Need a little help with this method

Question

this is what i need to do:
Add a static method Account consolidate(Account acct1, Account acct2) to your Account class that creates a new
account whose balance is the sum of the balances in acct1 and acct2 and closes acct1 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 (a random number).
? Two accounts with the same number cannot be consolidated. Otherwise this would be an easy way to double your
money!
right now i have this code but im not too positive i did it right (and i know its not done, but i just need some tips on what to do)
     public static Account AccountConsolidate(Account acct1, Account acct2)
          String name1 = acct1.getName();
          String name2 = acct2.getName();
          if(name1.equals(name2));
          newAccount = acct1.getBalance() + acct2.getBalance();
          newAccount = newAccount.getAcctNum();
          close acct2;
          return newAccount;
     }

Answer 1

1. "close" is not a Java keyword.
2. "newAccount" is being assigned twice.
Not that there's anything wrong with that but what's
the first assignment doing?
3. "newAccount" seems to be an int but your
method signature says to return an Account
object.this is my entire code, and i made some changes in the consolidateAccount method
// Account.java
// A bank account class with methods to deposit to, withdraw from,
// change the name on, and get a String representation
// of the account.
public class Account
     private double balance;
     private String name;
     private long acctNum;
     private static int numAccounts;
     private double newAccount;
//Constructor -- initializes balance, owner, and account number
     public Account(double initBal, String owner, long number)
          balance = initBal;
          name = owner;
          acctNum = number;
          numAccounts++;
// Checks to see if balance is sufficient for withdrawal.
// If so, decrements balance by amount; if not, prints message.
     public void withdraw(double amount)
          if (balance >= amount)
          balance -= amount;
          else
          System.out.println("Insufficient funds");
// Adds deposit amount to balance.
     public void deposit(double amount)
          balance += amount;
// Returns balance.
     public double getBalance()
          return balance;
//Returns number of accounts created
     public static int getNumAccounts()
          return numAccounts;
// Returns name on the account
     public String getName()
          return name;
// Returns account number
     public long getAcctNum()
          return acctNum;
// Close the current account.
     public void close()
          if (balance == 0)
          numAccounts--;
          System.out.println("CLOSED");
// Consolidates two accounts into one account.
     public static Account AccountConsolidate(Account acct1, Account acct2)
          String name1 = acct1.getName();
          String name2 = acct2.getName();
          if(name1.equals(name2));
          newAccount = acct1.getBalance() + acct2.getBalance();
          newAccount = newAccount.getAcctNum();
          Account consolidated = new Account(balance, name, newNumber);
          return consolidated;
// Returns a string containing the name, account number, and balance.
     public String toString()
          return "Name:" + name +
          "\nAccount Number: " + acctNum +
          "\nBalance: " + balance;
