Be aware, it is **not** a duplicate of [Why start an ArrayList with an initial capacity?](https://stackoverflow.com/questions/15430247/why-start-an-arraylist-with-an-initial-capacity)

Looking into the source code of the `java.util.ArrayList` class, starting from at least java 1.8 I see the following code:

```
/**
 * Constructs an empty list with an initial capacity of ten.
 */
public ArrayList() {
    this.elementData = DEFAULTCAPACITY_EMPTY_ELEMENTDATA;
}

```

Where 

```
private static final Object[] DEFAULTCAPACITY_EMPTY_ELEMENTDATA = {};

```

Though the [javadoc](https://docs.oracle.com/javase/8/docs/api/java/util/ArrayList.html#ArrayList--) officially states:

> 
> Constructs an empty list with an initial capacity of ten.
> 
> 
> 

I outline: **...an initial capacity of ten**. Where is this *ten*?

Am I completely mad and missing something, or there is simply a javadoc bug here?

**UPD:** How it looked like prior java 1.8:

```
public ArrayList(int initialCapacity) {
    super();
    if (initialCapacity < 0)
        throw new IllegalArgumentException("Illegal Capacity: "+
                                           initialCapacity);
    this.elementData = new Object[initialCapacity];
}

/**
 * Constructs an empty list with an initial capacity of ten.
 */
public ArrayList() {
    this(10);
}

```
