Question

You will turn in a java file named "MyMethods.java". It will contain one class named "MyMethods". That class will contain three methods.

These methods must be in JOptionPane and must contain:

1. getAnInt will return a value of type int, and take as an argument a string to prompt the user. The actual prompt presented to the user should include not only the string argument, but also the information that the user may press Cancel or enter an empty string to signal that the user does not want to enter any more. The method should use a post-test loop and a try...catch to handle user mis-typing. If the user "bails out early", the method will signal that to the calling program by setting a global boolean named "userCancelled" to true.
2. getA_Double will be pretty much the same as getAnInt, except it will parse and return a double.
3. printReport will produce a report. Its inputs (as arguments, not globals), in order will be
   an int giving the number of products in the order
   a String array, of product names
   an int array, of quantities
   a double array of prices,
   and a double, the tax rate, where 0.101 means 10.1% tax rate.
