Create a Bank Account class with the Main program file above.

Your Bank Account class should have the following

• Fields




• a Private ID  (int)


• a private Name (String)


• a private balance (double)




• Methods




• A default constructor




• that sets the ID to 0


• the balance to 0


• the name to "unknown"




• A full constructor




• That accepts all three values and sets the values accordingly.




• A to String() method




• That returns a string in the format


• 
  Name [ID] = $balance
  


• Example: Betty  [1233203]  = $105.51




• getName()


• getBalance()


• getID()




• These should just return the values with no changes.




• setName()




• This should change the name on the account, and only the name.




• changeBalance(double x)




• This should add the amount x to the balance.


• if x is negative you still add it, but the balance should go down.


• If the balance is negative, then set it to zero before finishing.
