GenIFTester $(30)$

Create two files for this exercise, one for the functional interface GenericInterface and one to test it called GenIFTester.

GenericInterface

This is a generic class of type T$.$

It has one abstract method called func that has a parameter of type T and returns a value of type T$.$

GenIFTester

This program can all be done in main

Create a Scanner to read from the keyboard.

Create a lambda function called reverse that implements GenericInterface This lambda accepts a variable of type String and reverses all the characters of the parameter. It returns the reversed String.

Then do three times

Request an input String.

Use reverse to reverse the String and print out the original String and the reversed String $($see Sample IO below$).$

Create a lambda function called factorial that implements GenericInterface This lambda accepts a variable of type int and calculates it$$s factorial value. It returns the int value. $($Note: Autoboxing will take place automatically or you can use Integer in place of int if you like

Then do three times

Request an input integer.

Use factorial to calculate the factorial value and print out the original number and factorial $($see Sample IO below$).$

Sample Input$/$Output

Enter a string to be reversed:

abcde

The entry abcde reversed is edcba

$4$

Enter a string to be reversed:

My Day Is Great $100\%$

The entry My Day Is Great $100\%$ reversed is $\%001$ taerG sI yaD yM

Enter a string to be reversed:

$39-87-$Grand

The entry $39-87-$Grand reversed is dnarG$-78-93$

Enter an integer to be factorialised:

$4$

factorial of $4=24$

Enter an integer to be factorialised:

$6$

factorial of $6=720$

Enter an integer to be factorialised:

$9$

factorial of $9=362,880$
