Make a copy of files for Exercise 1 into a new folder for Exercise2 11. Another strategy to validate user inputs is to test the attribute value in its corresponding mutator method. Use the rules for valid data from Exercise 1. If the value of the attribute is valid, save the new value in the appropriate attribute and return a value of true. If the value is invalid, do NOT change the attribute and return a value anexay: Ex2 jim java Tradestock of false.

Add a default constructor to the Stock class. Set the value of the name and symbol to the empty String 14. Add mutators for the name and symbol using the rules for valid data from Exercise 1. 15. Modify the code in the main method in the TradeStock class to use the default constructor to create an empty object. 16. Then use the mutators to validate the user-entered data. Test the return value to determine if the user input is valid. If the return value is false, print the same error messages as in Exercise 1 and terminate the program 17. The output of the program should be exactly the same as Exercise 1. Remember to test the program thoroughly with valid and invalid data
