I think you mean

<blockquote>
 Should I call <code>element[0]</code> the "zeroth" element or the "first" element?
</blockquote>

IMO, programmers often refer to it as the first element of an array. But you can also say that it is the element at index 0.

You see what I mean? In English, <code>element[0]</code> is always the first element. You can look up the word "first" in a dictionary to verify this. To literally "translate" <code>element[0]</code> into English, that would be "The element at index 0".

The first element of an array is located at index 0.

The second element of an array is located at index 1.

The third element of an array is located at index 2.

...

Basically, the number (as you say) of an array's element is the value of the index plus one.

I really like how Sweeper explained it. Let me add a sample piece of code to clarify a few details:

<pre><code>class MyClass {
 public static void main(String[] args) {
 // declare an array of integers
 int[] arr;

 // allocates memory for 3 integers
 arr = new int[3];

 // initialize first element
 arr[0] = 100;
 // initialize second element
 arr[1] = 200;enter code here
 // and so forth
 arr[2] = 300;

 System.out.println("Element at index 0: "
 + arr[0]);
 System.out.println("Element at index 1: "
 + arr[1]);
 System.out.println("Element at index 2: "
 + arr[2]);
 }
} 
</code></pre>

The output from this program is:

<pre><code> Element at index 0: 100
 Element at index 1: 200
 Element at index 2: 300
</code></pre>

For index 0, the element value is 100 and it is the 'first' element of the array. Or in other words, if you are referring to the n-th element of the array, it's index would be (n-1).

blocks|key|225517|text|你所说的编号到底是什么意思。数组按顺序排列数据，我们可以通过索引进行访问。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|225518|在Java中，正如其他人所指出的，索引从0开始|225519|你到底想用编号来表示什么？|225520|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

What exactly do you mean by numbering. Arrays arrange data in sequential manner and we can access by an index. 

In Java as others have pointed index starts from 0 

What exactly are you trying to indicate by numbering ?

blocks|key|4922884|text|您也应该从0开始元素编号。这只会使事情变得简单，并有助于避免很多混乱。为了进一步说明，你应该遵循一个术语，这样你就不需要记住它，也不会感到困惑。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4922885|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

You should start your element numbering from 0 as well. This just keeps things simple and helps avoid a lot of confusion. To elaborate further, you should just follow one nomenclature, so you dont have to remember it and dont get confused.

I'm trying to learn the concept of index and element in Java. I have seen two versions of representations for elements and am not sure which one is correct.

For an array with 4 elements, the first version assigns <code>Element(0)</code> to the first element, <code>Element(1)</code> to the second element and so on. This version is shown as the graph below.

<a href="https://i.stack.imgur.com/A696o.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/A696o.png" alt="enter image description here"></a>

The second version, <code>Element(1)</code> is assigned to the first element, <code>Element(2)</code> is assigned to the second element and so on.

I'm very confused as to which version of representing elements is correct and which is wrong, this is causing me a lot of confusion.

Should element numbering start from 0 or 1 in Java?

我正在努力学习Java中的索引和元素的概念。我见过两种表示元素的版本，不确定哪一种表示是正确的。对于包含4个元素的数组，第一个版本将Element(0)分配给第一个元素，Element(1)分配给第二个元素，依此类推。此版本如下图所示。​​第二个版本，Element(1)分配给第一个元素，Element(2)分配给第二个元素，依此类推。对于表示元素的哪个版本是正确的，哪个版本是错误的，我非常困惑，
