Question

Hello,

I would like to change the current menu in my existing java program. What I'm saying is that I would like to use array to create my menu instead of the basic one that it was already created. In addition, I would like to implement some methods, accessors, and mutators. This is my existing java program code:

import java.text.DecimalFormat;
import java.util.Date;
import java.util.Random;
import java.util.Scanner;
class Mac190Restaurant1
{
public static void main(String args[])
{
MenuBook obj=new MenuBook();
obj.menu();
}
}
class MenuBook
{
void menu()

int ItemNum = 0;
double Tax = 0;
double NYTax = 8.78;
double SubTotal= 0;
double Total =0;
double TotalFinal = 0;
System.out.println("//////////////// Mac King Fast Food ////////////////");
