Banks and other financial service companies offer many types of accounts for client’s to invest their fund– every one of them has a notion of their current value , but the details of calculating such value depends upon the exact nature of the account. Write an abstract class , Account, with the following: – an integer static variable , nextId initialized to 10001 – an integer instance variable , id – a string instance variable name – a constructor that accepts a single string parameter used to initialize the name instance variable . The constructor also assigns to id the value of nextId which is then incremented . – two accessor methods , getId and getName which return the values of the corresponding instance variables – an abstract method named getValue that accepts no parameters and returns and object of type Cash.
