Method Detail

insert

public boolean insert(int x_index,
                      int y_index,
                      E element)

Inserts a new element at the determinated coordenate. If the coordenate already exists in this BidimensionalArray, the old element is replaced by the specified element.

Parameters:

x_index - Represents the "x" position, as a cartesian plane.

y_index - Represents the "y" position, as a cartesian plane.

element - The element to be added.

insertAtRow

public void insertAtRow(int row,
                        E element)

insertAtColumn

public void insertAtColumn(int column,
                           E element)

get

public E get(int x_index,
             int y_index)

Gets the element at the determinated position. Returns null if the position is not assigned.

Parameters:

x_index - Represents the "x" position, as a cartesian plane.

y_index - Represents the "y" position, as a cartesian plane.

remove

public E remove(int x_index,
                int y_index)

replace

public void replace(int x_index,
                    int y_index,
                    E element)

toString

public java.lang.String toString()

Overrides:
