Start by downloading CS201_Lab3.zip and importing
it into Eclipse. You should see a project called CS201_Lab3.
Implement the following static methods in the Arrays class:
- readArray: Takes two parameters, keyboard and numElements.
keyboard is a Scanner object you can use to read input
from the user. numElements is the number of integer values
to read. The method should return a reference to an array
containing the requested number of integer values.
- printArray: Takes a parameter arr, an array of integer
values. The method should print out the element values in
- reverseArray: Takes a parameter arr, an array of integer values.
The method should reverse the values in the elements of the array.
For example, if passed an array containing the values 1 2 3,
the method should re-arrange the contents of the array so that it
contains the values 3 2 1.
A main method is provided for testing - you won't need
to change it.
When you run the main method, you should see output
looking something like this (user input in bold):
How many values?
Please enter 5 values:
9 0 1 2 5
You entered the following values:
9 0 1 2 5
Now I am going to reverse the array for you...
Here are the reversed array values:
5 2 1 0 9
When you are done, save the project (CS201_Lab3) to a zip file by right-clicking it
Upload the saved zip file to the Marmoset server as lab3.
