Class to be used in questions 1 and 2:

public classAccountRecord { private intaccountNo; privateString fullName;private doublebalance;

// initialize a record

publicAccountRecord(intacctNo, String name,doublebal) { setAccountNo( acctNo ); setFullName( name ); setBalance( bal );

}// end four-argument AccountRecord constructor

// set account number no

public voidsetAccountNo(intacctNo ) { accountNo = acctNo;

}// end method setAccountNo

// get account number nopublic intgetAccountNo() {returnaccountNo;

}// end method getAccountNo

// set full name

public voidsetFullName( String name ) { fullName = name;

}// end method setFullName

// get full namepublicString getFullName() {returnfullName;

}// end method getFullName

// set balance

public voidsetBalance(doublebal ) { balance = bal;

}// end method setBalance

// get balancepublic doublegetBalance() {returnbalance;

}// end method getBalance

}// end class AccountRecord

1. Make a public class called ReadAccounts. This class will read a file ("accountsData.txt") where the data is "Text-based". Once the file has been read, you must print the total sum of the balances. The data must be read in an array. (Use the AccountRecord class mentioned above).

2. Make a public class called WriteAccounts. This class will write to a file ("accountsData.txt") where the data is "Text-based". The program should ask several accounts, and save the data in an array, until it indicates that it is the end, then save each record or array to a file.(Use the AccountRecord class).
