removeElementAt
public void removeElementAt(int i) Deletes the component at the specified index. Each component in this vector with an index greater or equal to the specified index is shifted downward to have an index one smaller than the value it had previously.- Parameters:
i
- Index of node to remove
-
setElementAt
public void setElementAt(int node, int index) Sets the component at the specified index of this vector to be the specified object. The previous component at that position is discarded. The index must be a value greater than or equal to 0 and less than the current size of the vector.- Parameters:
node

- Index of where to set the node
-
elementAt
public int elementAt(int i) Get the nth element.- Parameters:
i
- Index of node to get- Returns:
- Node at specified index

- the index of the first occurrence of the object argument in this vector at position index or later in the vector; returns -1 if the object is not found.
-
indexOf
public int indexOf(int elem) Searches for the first occurence of the given argument, beginning the search at index, and testing for equality using the equals method.- Parameters:
