createShapes
public Shape[] createShapes(int count)
Since we only have 4 shapes, the method will start with the first shape and keep cycling through the shapes in order.- Parameters:
count
- The number of shapes to be created- Returns:
- the first n shapes
-
nextShape
public Shape nextShape()
Return the next shape- Returns:
- the next shape
-
createStrokes
public Stroke[] createStrokes(int count)
Create a given number ofStroke
s- Parameters:
count
- The number of strokes to be created- Returns:
- the first
count
strokes
-
nextStroke
public Stroke nextStroke()
method always return a new BasicStroke with 1.0f weight- Returns:
- a new BasicStroke with 1.0f weight
-
createPaint
public Paint[] createPaint(int count)
return an array of Paint with different colors. The current implementation will cycle through 12 colors if a line graph has more than 12 entries- Parameters:
count
- The number ofPaint
s to be created- Returns:
- an array of Paint with different colors
-
nextPaint
public Paint nextPaint()
The method will return the next paint color in the PAINT_ARRAY. Rather than return a random color, we want it to always go through the same sequence. This way, the same charts will always use the same color and make it easier to compare side by side.- Returns:
- the next paint color in the PAINT_ARRAY
