User Input Multiple Integer Variable Values in a Single Line (Java)

Question

This is the output I'm trying to create:

Please enter food servings separated by a blank in the order

Vegetables & Fruit, Grain Products, Milk & Alt, Meat & Alt: 8 7 1 3

Food Group Servings

Vegetables & Fruit 8

Grain Products 7

Milk & Alternatives 1

Meat & Alternatives 3

How can I accept multiple integers in the same line from user input, whilst assigning those integers to their own variables?

You can split the input by spaces and assign them to their own variables

String input = blah;
String[] split = input.split("\\s+");

int veg = 0;
int milk = 0;
//add more variables

veg = Integer.parseInt(split[0]);
milk = Integer.parseInt(split[1]);
//add more stuff here

And what happens if the user only enters 2 values instead of 4 ? or enters :1 1w 4 8 ?
