Looking for someone to comment in an explanation to each line of code and explain what it is doing. I wrote this code in a tutoring session with some others and now i don't get it anymore.

import java.util.ArrayList;

public class BankAccount { //create an array list Account object with accounts inside private String accountHolder; private ArrayList accounts;

public BankAccount() { accountHolder = ""; accounts = new ArrayList();

}

public BankAccount(String name) { accountHolder = name; accounts = new ArrayList();

}

public void setAccountHolder(String name) { accountHolder = name; }

public String getAccountHolder() { return accountHolder; }

public void addAccount(Account acc) { accounts.add(acc);

}

public String displayBankAccount() { String output = ""; output = output + " "; output = output + "Account Holder: " + accountHolder + " ";

for (int i = 0; i < accounts.size(); i++) { Account acc = accounts.get(i); output = output + (acc.displayAccount()); }

return output;

}

public ArrayList getAccounts() { return this.accounts; }

}//end of bank account class
