In Java, how do get the program to accept the following user input and implement the command?

Example Code so far:

package com.egyptianExample;

import java.util.$*$;

import org.json.simple.$*$;

public class EgyptianPyramidsAppExample $\{$

protected Pharaoh$[]$ pharaohArray;

protected Pyramid$[]$ pyramidArray;

$//$ create and start the app

EgyptianPyramidsAppExample app $=$ new EgyptianPyramidsAppExample$()$;

app.start$()$;

$\}$

$//$ main loop for app

public void start$()\{$

Scanner scan $=$ new Scanner$($System$.$in$)$;

Character command $=\text{'}\_\text{'}$;

$//$ loop until user quits

while $($command $!=\text{'}$q$\text{'})\{$

printMenu$()$;

System.out.print$("$Enter a command: $")$;

command $=$ menuGetCommand$($scan$)$;

executeCommand$($scan$,$ command$)$;

$\}$

$\}$

$//$ constructor to initialize the app and read commands

public EgyptianPyramidsAppExample$()\{$

$//$ read egyptian pharaohs
