PLEASE HELP PROJECT ME GOT EXAM NEXT WEEK

Question

I dont know how to do the code code comments that are listed
// ask for fields needed for an account
// declare local variables and store the information in these
// ask whether it is a checking or savings. Read in a char datatype named which
// ask for the monthly fee and read it into a variable
// ask whether it is a checking or savings. Read in a char datatype named which
// ask for the interest rate and read it into a variable
// create an instance of a savings account and add it to the array
public static void process(Account[] acct, int num)
// use a for loop to calculate all the new balances
public static void printAll(Account[] acct, int num)
// use a for loop to print out all of the accounts
public static int addAccount(Account[] a, int num, String name)
// ask for fields needed for an account
JOptionPane.showInputDialog( "Enter Name" );
JOptionPane.showInputDialog( "Enter Address" );
JOptionPane.showInputDialog( "Enter Phone Number" );
JOptionPane.showInputDialog( "Enter Date of Birth" );
JOptionPane.showInputDialog( "Enter Social Security Number" );
JOptionPane.showInputDialog( "Enter Account Number" );
// declare local variables and store the information in these
// ask whether it is a checking or savings. Read in a char datatype named which
JOptionPane.showInputDialog("Enter checking or savings 'C','S'");
if (which=='C')
// ask for the monthly fee and read it into a variable
JOptionPane.showInputDialog("Enter monthly fee");
// create an instance of a checking account and add it to the array
else if (which=='S')
// ask for the interest rate and read it into a variable
// create an instance of a savings account and add it to the array
return ++num;
public static void sortAccount(Account[] a, int num)
for(int pass = 1; pass < num; pass++)
for(int pair = 1; pair < num; pair++)
if(a[pair].compareTo(a[pair - 1]) < 1)
Account temp = a[pair - 1];
a[pair - 1] = a[pair];
a[pair] = temp;
public static void process(Account[] acct, int num)
// use a for loop to calculate all the new balances
public static void printAll(Account[] acct, int num)
// use a for loop to print out all of the accounts

Answer 1

ok here is the whole program
here is where I am having trouble inder the Banking part I have done everythng else and now I am stuck
