Q3 Write a class called "SumAndAverage" to produce the sum of 1, 2, 3, ..., to N, where N is a positive integer number inputted by the user from the keyboard. The program should use the 'Do-While loop'; 1. check the user's input, and ask the user to re- input a valid value if N is not a positive integer; compute and display the sum and the average of 1, 2, 3,., to N; 2. 3. The output of the program should be: Please input a positive integer number N: -1 Please input a positive integer number N: 10O The sum from 1 to 100 is: 5050 The average is: 50.5
