How would I store values in an array in java?

I want to store non "h" values in an array. So to give you a background, I need to make a basic cash register that accepts 5 items in an array with a price on them. Nevertheless, some items will have HST(tax) included with them. To know which items have tax and which don't. The user will press h or H before or after entering the dollar amount. I have stored the values with the HST in an array, but how would I store the non-HST values?

Sample input:

4.565H
H2.3435
4.565h
5.234
5.6576h

Sample Output:

HST Values:
4.565
2.3435
4.565
5.6576
Non-HST Values
5.234

My Code:

import java.util.Scanner;
class Main {
public static void main(String[] args) {
// Create scanner object and set scanner variables
Scanner inp = new Scanner(System.in);
System.out.println("Press any key to start");
String key = inp.nextLine();
System.out.println("\nEnter the amount of each item");
System.out.println("Up to 5 inputs are allowed!\n");
// Initialize counter and index variables to use it in the while loop
int counter = 0;
int index = 0;
// Create a double array variable, and set the limit to 5
double[] numbers = new double[5];
// Create a boolean variable to use it in the while loop
boolean go = true;
while (go) {           
String value = inp.nextLine();      
value = value.toLowerCase();
// Set the index value to "h" or "H"
int indexOfh = value.indexOf('h');
boolean containsh = (indexOfh == 0 || indexOfh == value.length() - 1);
if (containsh) { //Validate h at beginning or end
numbers[index] = Double.parseDouble(value.replace("h", ""));
index++;
System.out.println("HST will be taken account for this value");
}
counter++;
if (counter == 5) {
go = false;
}
}
System.out.println("HST Values:");
for (int i = 0; i < numbers.length; i++) {
System.out.println(numbers[i]);
}
}
}

I would suggest you to work with ArrayList instead:

import java.util.ArrayList;
import java.util.Scanner;
class Main {
public static void main(String[] args) {
// Create scanner object and set scanner variables
Scanner inp = new Scanner(System.in);
System.out.println("Press any key to start");
String key = inp.nextLine();
System.out.println("\nEnter the amount of each item");
System.out.println("Up to 5 inputs are allowed!\n");
// Initialize counter and index variables to use it in the while loop
int counter = 0;
// Create a double array variable, and set the limit to 5
ArrayList<Double> numbers = new ArrayList<Double>();
// Create a boolean variable to use it in the while loop
boolean go = true;
while (go) {           
String value = inp.nextLine().toLowerCase();
int indexOfH = value.indexOf('h');
if (indexOfH == 0 || indexOfH == value.length() - 1) { //Validate h at beginning or end
numbers.add(Double.parseDouble(value.replace("h", "")));
System.out.println("HST will be taken account for this value");
}
counter++;
if (counter == 5)
go = false;
}
System.out.println("HST Values:");
System.out.println(numbers);
}
}

You just need two arrays, one for H values and the other for non H. Why not use lists? Lists would be better

However, if the requirement is arrays, just store the h values by checking 'H' values like you have, and if index of 'H' is -1 that means the value does not contain h, then just add those to the other array and print it out as well at the end.
