Java program
Create two classes based on the java code below. One class for the main method (named InvestmentTest) and the other is an Investment class. The InvestmentTest class has a main method and the Investment class consists of the necessary methods and fields for each investment as described below.
1.The Investment class has the following members:
a. At least six private fields (instance variables) to store an Investment name, number of shares, buying price, selling price, and buying commission and sales commission.
b. Write set and get methods to access each of the private fields
c. “InvestmentSummary” method to print Investment Information including the result of
3. Create two different objects of the investment class
4. Create an object of java.util.Scanner to input the information about each investment, one at a time form the keyboard, and track the information in the proper Investment objects by placing calls to the proper set methods for each of the two objects.
5. When invoking the InvestmentSummary method, use the get method found in the Investment class to access the private members.
a. Print the investment information including gain or loss using the string %s specifier.
