Part I: Code an operation class TempConvertWithValidate using any version of Validator discussed in the text in Chapter 5, so it can verify all invalid data entries in the temperature conversion you did in Lab 1. Understand the examples of Validators first before you start to do this part of lab. In your code you will display a menu using JOptionPane first as follows: 1. Convert temperature from Celsius to Fahrenheit 2. Convert temperature from Celsius to Fahrenheit 3. Quit You will verify these 3 options and then in the method calls to do the temperature conversions, you will also verify the input data from the user ranged from -100 to 200. All data entries other than this range

are considered as invalid and you must verify them using any versions of the Validator class provided in the example code from the text. You will code a driver class TempCovertWithValidateApp to test your application. Your program must continue to run until the user selects Quit to terminate the execution. Document each of your source codes as required above. Part II - Code all operations including the process of input data and the while loop for continuously running the program in the operation class, not in the driver class. Therefore, your driver class for test looks as follows: public class TempCovertWithValidateApp2 { public static void main(String[] args) { TempCovertWithValidate temp = new TempConvertWithValidate(); //Create object temp.start(); //call method to execute the operation class } } You may submit Part I and II as one project. But suggest you code them separately first as your learning process. Document each of your source codes as required above.

part |I: must verify letter entries for selection; must verify all data entries for temp values including letters;
