- Field Detail
  - initialCapacity
```
public static int initialCapacity
```
- Constructor Detail
  - DoubleArrayList
```
public DoubleArrayList()
```
    Constructs an empty list with an initial capacity.
  - DoubleArrayList
```
public DoubleArrayList(int initialCapacity)
```
    Constructs an empty list with the specified initial capacity.
  - DoubleArrayList
```
public DoubleArrayList(double[] data)
```
    Constructs a list containing the elements of the specified array. The list instance has an initial capacity of 110% the size of the specified array.
- Method Detail
  - toArray
```
public double[] toArray()
```
    Returns an array containing all of the elements in this list in the correct order.
  - get
```
public double get(int index)
```
    Returns the element at the specified position in this list.
  - size
```
public int size()
```
    Returns the number of elements in this list.
  - remove
```
public double remove(int index)
```
    Removes the element at the specified position in this list. Shifts any subsequent elements to the left (subtracts one from their indices).
    
    Parameters:
    index - the index of the element to remove
    
    Returns:
    the value of the element that was removed
    
    Throws:
    
    java.lang.UnsupportedOperationException - when this operation is not supported
    
    java.lang.IndexOutOfBoundsException - if the specified index is out of range
  - removeRange
```
public void removeRange(int fromIndex,
               int toIndex)
```
    Removes from this list all of the elements whose index is between fromIndex, inclusive and toIndex, exclusive. Shifts any succeeding elements to the left (reduces their index).
  - set
```
public double set(int index,
         double element)
```
    Replaces the element at the specified position in this list with the specified element.
    
    Parameters:
    index - the index of the element to change
    element - the value to be stored at the specified position
    
    Returns:
    the value previously stored at the specified position
  - add
```
public void add(double element)
```
    Appends the specified element to the end of this list.
  - add
```
public void add(int index,
       double element)
```
    Inserts the specified element at the specified position in this list. Shifts the element currently at that position (if any) and any subsequent elements to the right (adds one to their indices).
    
    Parameters:
    index - the index at which to insert the element
    element - the value to insert
  - addAll
```
public void addAll(double[] data)
```
    Appends all of the elements in the specified array to the end of this list.
  - addAll
```
public void addAll(int index,
          double[] data)
```
    Appends all of the elements in the specified array at the specified position in this list.
  - clear
```
public void clear()
```
    Removes all of the elements from this list. The list will be empty after this call returns.
  - contains
```
public boolean contains(double data,
               double delta)
```
    Returns true if this list contains the specified element.
  - indexOf
```
public int indexOf(double data,
          double delta)
```
    Searches for the first occurrence of the given argument.
  - lastIndexOf
```
public int lastIndexOf(double data,
              double delta)
```
    Returns the index of the last occurrence of the specified object in this list.
  - isEmpty
```
public boolean isEmpty()
```
    Tests if this list has no elements.
  - ensureCapacity
```
public void ensureCapacity(int mincap)
```
    Increases the capacity of this ArrayList instance, if necessary, to ensure that it can hold at least the number of elements specified by the minimum capacity argument.
  - trimToSize
```
public void trimToSize()
```
    Trims the capacity of this instance to be the list's current size. An application can use this operation to minimize the storage of some instance.
