What conclusion can you draw from the following paragraph? The ATA-3 standard improves on the ATA-2 in that the disk has the capability to alert the operating systems if its
operations are degrading. The ATA-4 standard supports transfer of data at speeds up to 33MBps, ATA-5 can transfer
data up to 66.6 MBps, and ATA-6 can transfer data up to 100 MBps.
The ATA-3 standard has a tendency to suffer more degradation of operations than ATA-2
Advances in ATA standards allow for large increases in data transfer speeds,
Each new ATA standard requires an increase in the number of connection pins.
The ATA-3 standard is the most advanced form of ATA device to date.

File account.java (see previous exercise) contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and return a string representation. note that the constructor for this class creates a random account number. save this class to your directory and study it to see how it works. then write the following additional code: 1. suppose the bank wants to keep track of how many accounts exist. a. declare a private static integer variable numaccounts to hold this value. like all instance and static variables, it will be initialized (to 0, since it’s an int) automatically. b. add code to the constructor to increment this variable every time an account is created. c. add a static method getnumaccounts that returns the total number of accounts. think about why this method should be static - its information is not related to any particular account. d. file testaccounts1.java contains a simple program that creates the specified number of bank accounts then uses the getnumaccounts method to find how many accounts were created. save it to your directory, then use it to test your modified account class.
