Rewrite the applyFunction method from the Module 7 Ungraded Practice Exercise solution that operated on int values. The method should now also accept a Function reference as an argument, and use this argument instead of creating an instance of the Half class. The new method signature looks like this:

public static int[] applyFunction(Function func, int... arrIn) { Create class called Print that implements the method evaluate() in the Function interface. This method prints the int value passed as an argument, followed by a concatenated space character " ", and returns the same argument it was passed.

Now write program that :

Prints an arbitrary number of int values using an instance of the Print class and the method described earlier Halves the values in the array and prints the value again, using the Half and Print classes and the method described earlier. */

/* Sample output (this time calling the method applyFunction with a Function reference argument which just prints a value, followed by calling the method applyFunction again but this time with a Function reference which halves the values).

The first call to the modified applyFunction looks like this:

int[] myArr = applyFunction(print, 2 ,4, 6, 8); where an instance of the Print class named "print" has been instantiated. The second call can use the myArr array reference returned by this call and pass an instance of the Half class which contains the evaluate method which halves its arguments.

Original values: 2 4 6 8

Halved values: 1 2 3 4 */

interface Function { int evaluate(int arg); class Half implements Function { @Override public int evaluate(int arg) { return arg/2; } } class print { int evaluate(int arg); } }

public class client { public static int[] applyFunction(Function func, int... arrIn) { int length = arrIn.length; int[] arrOut = new int[length]; // call evaluate for all elements of arrIn for (int i = 0; i < length; i++) { arrOut[i] = func.evaluate(arrIn[i]); } return arrOut; } public static void main(String[] args) { // halve the values int[] myArr = applyFunction(print, 2, 4, 6, 8); System.out.println("The first call to the modified applyFunction looks like this: "); for (int value : myArr) { System.out.print(value + " "); } System.out.println(); } }
