Write a JAVA program that asks the user how many numbers will be entered and then has the user enter those numbers. When this is done, report to the user the position of the first 7 entered and the last 7 entered. By position we mean, for example, that if the first 7 is the 2nd number entered then its position would be 2. Turn in the following 3 outputs exactly as you see them below to demonstrate that your program works in each case.

Sample screen output 1:

 How many numbers will be entered? 8 Enter num: 5 Enter num: 7 Enter num: 6 Enter num: 7 Enter num: 7 Enter num: 3 Enter num: 8 Enter num: 6 The first 7 was in position 2 The last 7 was in position 5 

Sample screen output 2:

 How many numbers will be entered? 8 Enter num: 5 Enter num: 2 Enter num: 6 Enter num: 7 Enter num: 1 Enter num: 3 Enter num: 8 Enter num: 6 The first 7 was in position 4 The last 7 was in position 4 

Sample screen output 3:

 How many numbers will be entered? 8 Enter num: 5 Enter num: 1 Enter num: 6 Enter num: 5 Enter num: 9 Enter num: 3 Enter num: 8 Enter num: 6 Sorry, no 7's were entered. 

Turn in your source code followed by 3 outputs, one that matches each of the three sample screen outputs given above.
