Q 1. Write the implementation java code for a class named Stockthat contains:

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

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

3. A double data field named previousClosingPrice that stores the stock price for the previous day.

5. An integer data field named ID that stores the identifier number of stock.

6. A constructor that creates a stock with the specified symbol, name, and ID.

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

double getChangePercent(){

return 100 * (currentPrice - previousClosingPrice) / previousClosingPrice;

}

Q 2. Draw the UML diagram for the class Stock.

Q 3. Write a test program that:

1. Create a random object from the Random class (java.util.Random). We will use this object for the ID number of Stock between (0 to 100).

2. Ask a user for the name and symbol of Stock. So, you should create two string variables in the test program.

3. Create a Stock object with the stock symbol (from the user), the name of symbol (from the user), and ID (from Random object by using nextInt(100) method).

4. Ask the user for the previous closing price and the current price. Note: Don't create two variables for them. You can use the Stockobject to assign the values of these two variables from the user.

5. Display the stock name, the stock symbol, the stock ID, and the pricechange percentage.
