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 depend upon the exact nature of the account.
write an abstract class, account, with the following:
1. an integer static variable, nextid initialized to 10001 2. an integer instance variable, id
3. a string instance variable name
4. 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.
5. two accessor methods, getid, and getname which return the values of the corresponding instance variables
6. an abstract method named getvalue that accepts no parameters and returns an object of type cash.

Acolor class has three public, integer-returning accessor methods: getred, getgreen, and getblue, and three protected, void-returning mutator methods: setred, setgreen, setblue, each of which accepts an integer parameter and assigns it to the corresponding color component. the class, alphachannelcolor-- a subclass of color-- has an integer instance variable, alpha, containing the alpha channel value, representing the degree of transparency of the color. alphachannelcolor also has a method named dissolve (void-returning, and no parameters), that causes the color to fade a bit. it does this by incrementing (by 1) all three color components (using the above accessor and mutator methods) as well as the alpha component value. write the dissolve method.
