Start by downloading CS201_Lab03.zip and importing it into Eclipse. You should see a project called CS201_Lab03.
Your task
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 the array.
-
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.
Testing
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? 5 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
