The following code is a stripped down version of a large project. The
question is why do I have to press ctrl z every time to get the
output? That is, say I type the following at the command line

1 - 3

and then press the enter key on my keyboard. I press ctrl z and I get
'The value is 1' . Then I press it again, I get a 'The value is '.
Then I press it again, I get 'The value is -', etc.  Ideas on how to
get how get the entire output out at once? Ideally what I would like
to do is when I type in the above, press the enter key, then, after I
press ctrl z,  get

The value is 1
The value is
found the minus sign
The value is 3


import java.util.Scanner;

public class hack {

    public static int getNextNumber(String [] storeValues) {
        String value = null;
        int i = 0;
        Scanner input = new Scanner(System.in);

        while(input.hasNextLine()) {

            try {
                storeValues[i++] = input.nextLine();
            } catch (IllegalStateException e) {
		return -1; //EOF
            }
        }

        return 0;
    }

    public static void main(String[] args) {
        String[] values = new String[100];

	char[] getNumber;
	int value;
	int i = 0;
        while ( ( value = getNextNumber(values) ) != -1) {
		getNumber = values[0].toCharArray();
		switch (value) {
			case 0: {
				System.out.println("The value is " + getNumber[i]);
				i++;
				break;
			}
			case '+': {
				System.out.println("found plus sign");
				i++;
				break;
			}
			case '-': {
				System.out.println("found minus sign");
				i++;
				break;
			}
			case '*': {
				System.out.println("found mult sign");
				i++;
				break;

			case '/': {
				System.out.println("found division sign");
				i++;
