1. Please write the following program in Python 3? Please also create the UML and test program. Please show all outputs.

(The Stock class) Design a class named Stock to represent a companys stock that contains:

A private string data field named symbol for the stocks symbol.

A private string data field named name for the stocks name.

A private float data field named previousClosingPrice that stores the stock price for the previous day.

Get and set methods for getting/setting the stocks previous price.

Get and set methods for getting/setting the stocks current price.

A method named getChangePercent() that returns the percentage changed from previousClosingPrice to currentPrice.

Draw the UML diagram for the class, and then implement the class. Write a test program that creates a Stock object with the stock symbol INTC, the name Intel Corporation, the previous closing price of 20.5, and the new current price of 20.35, and display the price-change percentage.
