public void add(int index,
                char v)

Throws UnsupportedOperationException.

Specified by:

add in interface CharList

Parameters:

index - the index at which to add the element. If index == size() the element is appended to this list.

v - the char value to add to this list.

Throws:

UnsupportedOperationException - unconditionally.

addAll

public boolean addAll(int index,
                      CharCollection c)

Throws UnsupportedOperationException.

Specified by:

addAll in interface CharList

Parameters:

index - the index at which to insert the elements of the specified collection. If index == size() the elements are appended to this list.

c - the collection whose elements to add to this list.

Returns:

true if this list was modified as a result of adding the elements of c; returns false otherwise.
