In this Java example code, how do I get this menu to display and function based on user commands?

The screenshot shows how the menu should be formatted, and the goal is so that the program can accept and respond accordingly to each command. This is the example code I have so far:

package com.app;

import java.util.Random;

import org.json.simple.JSONArray;

public class CavazosExample $\{$

$$ public static void main$($String$[]$ args$)\{$

$$ String fileName $=$

$"/$Users$/$envyi$/$Documents$/$GitHub$/$General$\_$Cavazos$\_$App$/$cavazosapp$/$src$/$main$/$java$/$com$/$app$/$commands$.$json";

$//$ read commands

$$ JSONArray commandJSONArray $=$ JSONFile.readArray$($fileName$)$;

$$ String$[]$ commandArray $=$ getCommandArray$($commandJSONArray$)$;

$$ System.out.println$($commandArray$)$;

$//$ print list of all commands

$$ System.out.println$("-----$ List of all commands $-----")$;

$$ print$($commandArray$)$;

$$ System.out.println$($

$"-----$ Issuing $5$ random commands from General Cavazos $-----"$

$)$;

$$ randomCommand$($commandArray$,5)$;

$\}$

$//$ randomly issue commands from General Cavazos

$$ public static void randomCommand$($String$[]$ commandArray, int numCommand$)\{$

$$ Random rand $=$ new Random$()$;

$$ System.out.printf$("$Number$\backslash$tCommand

$")$;

$$ System.out.printf$("------\backslash$t$---------------$

$")$;

$$ for $($int i $=0$; i $$ numCommand; i$++)\{$

$$ int randIndex $=$ rand.nextInt$($commandArray$.$length$)$;

$$ System.out.printf$("\%04$d$\backslash$t$\%$s

$",$ i$,$ commandArray$[$randIndex$])$;

$\}$

$\}$

$//$ print command array

$$ public static void print$($String$[]$ commandArray$)\{$

$$ System.out.printf$("$Number$\backslash$tCommand

$")$;

$$ System.out.printf$("------\backslash$t$---------------$

$")$;

$$ for $($int i $=0$; i $$ commandArray.length; i$++)\{$

$$ System.out.printf$("\%04$d$\backslash$t$\%$s

$",$ i$,$ commandArray$[$i$])$;

$\}$

$\}$

$//$ get array of commands

$$ public static String$[]$ getCommandArray$($JSONArray commandArray$)\{$

$$ String$[]$ arr $=$ new String$[$commandArray$.$size$()]$;

$//$ get names from json object

$$ for $($int i $=0$; i $$ commandArray.size$()$; i$++)\{$

$$ String command $=$ commandArray.get$($i$).$toString$()$;

$$ arr$[$i$]=$ command;

$\}$

$$ return arr;

$\}$

$\}$
