Hellow I'm intro to Java can you only use printf for all printings, thanks

Design a class named Stock that contains:

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

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

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

* A double data field named currentPrice that stores the stock price for the current time.

*A constructor that creates a stock with the specified symbol and name.

*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 ORCL, the name Oracle Corporation, and the previous closing price of 34.5. Set a new current price to 34.35 and display the price-change percentage.
