In object-oriented programming (OOP), private attribute means that we don't want this attribute to be accessed outside the class object. Explore how to define a private method/ attribute and finish the following questions. Design a class named Stock to represent a company's stock that contains: Initiate method: • A private string data field named symbol that stores stock's symbol • A private string data field named name that stores stock's name • A private float data field named previous ClosingPrise that stores previous day's stock price • A private float data field named current Price that stores current stock price Instance method: . A get method for returning the stock name • A get method for returning the stock symbol . Get and set methods for getting/setting stock's previous price . Get and set methods for getting/setting stock's current price • A method famed getChangePercent) that returns the percentage changed from previous ClosingPrice to current Price After you finish the class construction, 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 3 the current price of 20.35. Display the price change percentage. Based on the class example you write, please discuss the benefits of OOP
