System.out.println() is missing tabs ("\t") on some lines

Question

I have a class, Variation, with three String fields: id, name, price. I populate a list of 25 of them with a random string of random characters, "name" plus + index (for name), and "price" + index (for price).

When I iterate through each Variation, I'm using:

System.out.println(i + "\tid: " + variation.id + "\tname: " + variation.name + "\tprice: " + variation.price);

My output is:

I/System.out: 0 id: 6N8D06S80DIEJQH9KJAG    name: name0 price: price0
I/System.out: 1 id: XCKGYA0W4YNKE25MRGKD    name: name1 price: price1

I/System.out: 24    id: FFIK3FR3K7ZKOYV77E2O    name: name24    price: price24

Here are the relevant parts of the code:

Main:

    List<Variation> variationsList = new ArrayList<>();

    void populateVariationsList() {
        for(int i = 0 ; i < 25; i++)
            variationsList.add(new Variation(getRandomId(), "name" + i, "price" + i));
    }

    String getRandomId() {
        String CHARS = "ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890";
        StringBuilder randomId = new StringBuilder();
        Random rnd = new Random();
        while (randomId.length() < 20)
            randomId.append(CHARS.charAt(rnd.nextInt(36)));
        return randomId.toString();
    }

    public void onResume() {
        super.onResume();
        for(int i = 0; i < variationsList.size(); i++) {
            Variation variation = variationsList.get(i);
            System.out.println(i + "\tid: " + variation.id + "\tname: " + variation.name + "\tprice: " + variation.price);
        }
    }

Variation.java:

public class Variation {

    String id;
    String name;
    String price;

    public Variation(String id, String name, String price) {
        this.id = id;
        this.name = name;
        this.price = price;
    }
}

It's not that important and I'm probably overlooking something silly, but can anyone see why it doesn't print all the tabs?

Answer 1

As everyone else has stated it's expected behavior. However, if you want uniform output (I'm pretty OCD about that) I would add an if else statement in the for loop of the onResume method that added a 0 before every single digit number, this should cause the tabs to all be uniform.

public void onResume() {
            super.onResume();
            for(int i = 0; i < variationsList.size(); i++) {
                Variation variation = variationsList.get(i);
                if(i < 10){
                    System.out.println( "0" + i + "\tid: " + variation.id + "\tname: " + variation.name + 
        "\tprice: " + variation.price);}
                else{
                     System.out.println(i + "\tid: " + variation.id + "\tname: " + variation.name + "\tprice: " + variation.price);
    }}}
