How would you call each method in the main? I am struggling to figure it out using Java.

$-$Method in the ArrayStack class $($name it numValues$),$ this method return the number of elements stored in the Stack $($not the capacity$).$

$-$Method in the ArrayStack class $($name it printStack$),$ this method prints the elements in the Stack $($in reverse order$).$

$-$Method in the Demo class $($name it reverseString$),$ call the method from the main$()$ and pass a string to it$.$ This method will do the following:

Receives a string $($sentence$,$ not just one word$).$

Stores the received string in an array$-$based stack

Prints the sentence in reverse.

Example:

Call statement: reverseString$("$Testing my reverseString method"$)$;

output: dohtem gnirtSesrever ym gnitseT

$-$Method in the Demo class $($name it reverseNumber$),$ call the method from the main$()$ and pass an integer to it$.$ This method will do the following:

Receives an integer.

Stores the received integer in an array$-$based stack

Prints the integer in reverse.

Example:

Call statement: reverseNumber$(5467)$;

output: $7645$
