Lab 12.1 — Array Information (ArrayInfo)

The file numbers.text contains a header value, followed by that many double values. Create an array of the appropriate size, populate the array with the doubles, and print out various information about the array (see below).

Sample Test Run

For example if the file numbers.text contains:

8
12.3
2.5
9.4
3.14
22.15
17
54.3
7.6

the program should produce the following output:

The array: {12.3, 2.5, 9.4, 3.14, 22.15, 17.0, 54.3, 7.6} contains 8 elements
The first element of the array is 12.3
The last element of the array is 7.6 and is at position 7
The middle element of the array is 3.14 and is at position 3
The largest element of the array is 54.3 and is at position 6
The smallest element of the array is 2.5 and is at position 1

Notes:

• You should be using methods for printing, and the max/min calculations.
  • You're on your honor here — I'm not making it an approval.
• Notice the array is printed using comma logic.
  • Even though I'm not holding you responsible for remembering the logic for reproduction on an exam, there's no reason you shouldn't use it in an assignment, where you have access to the proper code in the lecture notes.
• Feel free to copy any of the code/methods from lecture 12 (there's no real need to use the first, last, or middle methods — — feel free to simply use the proper subscripts).
• While the max method presented inthe lecture notes is useful, it is not enough; you are not just being asked to print out the largest and smallest value, you are also required to print out their positions (i.e., indexes in the array). You thus should consider writing a maxPos method that returns the index (rather than the actual value) of the largest element in the array (same for minimu).

Lab 12.2 — Reverser (Reverser) (Approval)

The file numbers.text contains a header value, followed by that many integer values. Read the values into an array, and print them out in reverse to the file reversed.text, preceded by a header value.

Sample Test Run

For example if the file numbers.text contains:

5
10
20
30
40
50

the program should produce the following output:

5
50
40
30
20
10
