The Graph Class IV

Graph.java

/** * Return the canvas as one string * * @return string representation of the canvas. */ public String toString() { String s = ""; for (int row = 0; row < rows; ++row) { for (int column = 0; column < columns; ++column) { s += canvas[row][column]; } s += "\n"; } return s; }

This could be improved by avoiding the inclusion of spaces that are followed by a line terminator only. Any volunteers?
