in Java :A variable like userNum can store a value like an integer. Extend the given program to print userNum values as indicated.

$(1)$ Output the user's input. $(2$ pts$)$

Note: This zyLab outputs a newline after each user$-$input prompt. For convenience in the examples below, the user's input value is shown on the next line, but such values don't actually appear as output when the program runs.

Enter integer:

$4$

You entered: $4$

$(2)$ Extend to output the input squared and cubed. Hint: Compute squared as userNum $*$ userNum. $(2$ pts$)$

Enter integer:

$4$

You entered: $4$

$4$ squared is $16$

And $4$ cubed is $64!!$

$(3)$ Extend to get a second user input into userNum$2.$ Output sum and product. $(1$ pt$)$

Enter integer:

$4$

You entered: $4$

$4$ squared is $16$

And $4$ cubed is $64!!$

Enter another integer:

$5$

$4+5$ is $9$

$4*5$ is $20$
