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.
