Problem:
Question 1: Create a class inherited from JFrame. In one panel in this frame, have two JTextFields and two JButtons. In another panel, put a label. When the user puts numbers in both of the test fields, one of the buttons will be for showing the sum of the two numbers in the label. The other button will be for displaying the product of the two numbers.
Question 2: Write an application that creates a HashSet of 10 integers. Write a method named removeDuplicates that takes a second HashSet of integers as its argument and ensures that this second set does not contain any elements from the first set.
Show the code, demonstrate it works properly and describe what it is doing.
