Method Detail

swap

public static void swap(Vector vec,
                        int xx,
                        int yy)

Swap two elements in a Vector given positions. Handles boundary conditions by not doing anything if out of bounds.

Parameters:

vec - is the Vector to use.

xx - is the index of one of the items to swap. It is zero-based.

yy - is the index of one of the items to swap. It is zero-based.

moveTo

public static void moveTo(Vector vec,
                          int xx,
                          int yy)

Move an item in a Vector from one position to another. Items are shifted over to the left as needed. Handles boundary conditions by not doing anything if out of bounds.

Parameters:

vec - is the Vector to use.

xx - is the index of the item to move from. It is zero-based.

yy - is the index of the position to move to. It is zero-based.

moveToFront

public static void moveToFront(Vector vec,
                               int xx)

Move the item at the specified position to the front of the Vector.

Parameters:

vec - is the Vector to use.

xx - is the index of the item to move to the front. It is zero-based.

moveToBack

public static void moveToBack(Vector vec,
                              int xx)

Move the item at the specified position to the back of the Vector.

Parameters:

vec - is the Vector to use.

xx - is the index of the item to move to the back. It is zero-based.

main

public static void main(String[] argv)
