Change your basic fee constant to the following variable

private static double basicFee = 10 ;

Make changes to methods that use this variable (was a constant)

Change your Student fee constant to the following variable

Write an updateCheckIntRate method
Write an accessor for the checkIntRate variable

Change toString methods to output the following information for the non interest accounts :

Initials Balance=<balance> fee charge = <fee charge>

Add the following to the Account class private data

private static String nextAccNum = "1234000";

In Account write

public static String getNewAccountNumber()

Create an Integer object with nextAccNum.

Create a primitive int variable and assign it the intValue from the Integer object plus 1.

assign nextAccNum the int created above.

return the primitive int value.
