Question

Hi guys a quick question. Im creating a Java menu below is a sample piece of the code. I am wondering if i set up 2 arrays in an “if” statement how can i refer to these arrays again. I know that because of scope the arrays get destroyed when moved out of the if statement. I wanted to refer to the arrays again if option P is selected.

public static void determineOption (char option) {

        if (option == 'A') {

        int class_number = Console.getInt("Enter how many students between 1-10");

        while (class_number < 1 || class_number > 10)
        class_number = Console.getInt("Enter how many students between 1-10");

        System.out.println("");


        String[] name = new String[class_number];
        int[] score = new int[name.length];

        for (int i=0; i<class_number; i=i+1) 
        {
            name[i] = Console.getString("Enter Name");
            score[i] = Console.getInt("Enter score");
        }

        }
        else if (option == 'P') {


        }

According to your logic it seems HashMap is suitable for this.

HashMap<String,Integer>

Your key is name and value is score. You could define this as class variable and use in both if else if cases.
