hashCode	back to summary
public int hashCode() Overrides java.lang.Object.hashCode. Implements java.util.List.hashCode. Doc from java.util.List.hashCode. Returns the hash code value for this list. The hash code of a list is defined to be the result of the following calculation: `int hashCode = 1; for (E e : list) hashCode = 31*hashCode + (e==null ? 0 : e.hashCode());` This ensures that `list1.equals(list2)` implies that `list1.hashCode()==list2.hashCode()` for any two lists, `list1` and `list2`, as required by the general contract of `Object#hashCode`.

subList back to summary

subList	back to summary
public List<T> subList(final int fromIndex, final int toIndex) Implements java.util.List.subList. Doc from java.util.List.subList. Returns a view of the portion of this list between the specified `fromIndex`, inclusive, and `toIndex`, exclusive. (If `fromIndex` and `toIndex` are equal, the returned list is empty.) The returned list is backed by this list, so non-structural changes in the returned list are reflected in this list, and vice-versa. The returned list supports all of the optional list operations supported by this list. This method eliminates the need for explicit range operations (of the sort that commonly exist for arrays). Any operation that expects a list can be used as a range operation by passing a subList view instead of a whole list. For example, the following idiom removes a range of elements from a list: `list.subList(from, to).clear();` Similar idioms may be constructed for `indexOf` and `lastIndexOf`, and all of the algorithms in the `Collections` class can be applied to a subList. The semantics of the list returned by this method become undefined if the backing list (i.e., this list) is structurally modified in any way other than via the returned list. (Structural modifications are those that change the size of this list, or otherwise perturb it in such a fashion that iterations in progress may yield incorrect results.) Parameters fromIndex:int low endpoint (inclusive) of the subList toIndex:int high endpoint (exclusive) of the subList Returns:List<T> a view of the specified range within this list

public List<T> subList(final int fromIndex, final int toIndex)

Implements java.util.List.subList.

Doc from java.util.List.subList.

Returns a view of the portion of this list between the specified fromIndex, inclusive, and toIndex, exclusive. (If fromIndex and toIndex are equal, the returned list is empty.) The returned list is backed by this list, so non-structural changes in the returned list are reflected in this list, and vice-versa. The returned list supports all of the optional list operations supported by this list.

This method eliminates the need for explicit range operations (of the sort that commonly exist for arrays). Any operation that expects a list can be used as a range operation by passing a subList view instead of a whole list. For example, the following idiom removes a range of elements from a list:

list.subList(from, to).clear();

Similar idioms may be constructed for indexOf and lastIndexOf, and all of the algorithms in the Collections class can be applied to a subList.

The semantics of the list returned by this method become undefined if the backing list (i.e., this list) is structurally modified in any way other than via the returned list. (Structural modifications are those that change the size of this list, or otherwise perturb it in such a fashion that iterations in progress may yield incorrect results.)

Parameters

fromIndex:int: low endpoint (inclusive) of the subList
toIndex:int: high endpoint (exclusive) of the subList

Returns:List<T>

a view of the specified range within this list

toArray	back to summary
public Object[] toArray() Implements java.util.List.toArray. Doc from java.util.List.toArray. Returns an array containing all of the elements in this list in proper sequence (from first to last element). The returned array will be "safe" in that no references to it are maintained by this list. (In other words, this method must allocate a new array even if this list is backed by an array). The caller is thus free to modify the returned array. This method acts as bridge between array-based and collection-based APIs. Returns:Object[] an array containing all of the elements in this list in proper sequence

toArray

back to summary

public Object[] toArray()

Implements java.util.List.toArray.

Doc from java.util.List.toArray.

Returns an array containing all of the elements in this list in proper sequence (from first to last element).

The returned array will be "safe" in that no references to it are maintained by this list. (In other words, this method must allocate a new array even if this list is backed by an array). The caller is thus free to modify the returned array.

This method acts as bridge between array-based and collection-based APIs.

Returns:Object[]: an array containing all of the elements in this list in proper sequence

toArray back to summary

toArray	back to summary
public <T> T[] toArray(final T[] a) Implements java.util.List.toArray. Doc from java.util.List.toArray. Returns an array containing all of the elements in this list in proper sequence (from first to last element); the runtime type of the returned array is that of the specified array. If the list fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the runtime type of the specified array and the size of this list. If the list fits in the specified array with room to spare (i.e., the array has more elements than the list), the element in the array immediately following the end of the list is set to `null`. (This is useful in determining the length of the list only if the caller knows that the list does not contain any null elements.) Like the `toArray()` method, this method acts as bridge between array-based and collection-based APIs. Further, this method allows precise control over the runtime type of the output array, and may, under certain circumstances, be used to save allocation costs. Suppose `x` is a list known to contain only strings. The following code can be used to dump the list into a newly allocated array of `String`: `String[] y = x.toArray(new String[0]);` Note that `toArray(new Object[0])` is identical in function to `toArray()`. Parameters <T> Doc from java.util.Collection.toArray. the component type of the array to contain the collection a:T[] the array into which the elements of this list are to be stored, if it is big enough; otherwise, a new array of the same runtime type is allocated for this purpose. Returns:T[] an array containing the elements of this list

public <T> T[] toArray(final T[] a)

Implements java.util.List.toArray.

Doc from java.util.List.toArray.

Returns an array containing all of the elements in this list in proper sequence (from first to last element); the runtime type of the returned array is that of the specified array. If the list fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the runtime type of the specified array and the size of this list.

If the list fits in the specified array with room to spare (i.e., the array has more elements than the list), the element in the array immediately following the end of the list is set to null. (This is useful in determining the length of the list only if the caller knows that the list does not contain any null elements.)

Parameters

<T>: Doc from java.util.Collection.toArray. the component type of the array to contain the collection
a:T[]: the array into which the elements of this list are to be stored, if it is big enough; otherwise, a new array of the same runtime type is allocated for this purpose.

Returns:T[]

an array containing the elements of this list
