public Random()

Method Detail

randomColor

public static Color randomColor()

Creates a random color

Returns:

a random graphics.colors.Color

randomInteger

public static Integer randomInteger(Integer low,
                                    Integer high)

Picks a random number between low and high (inclusive)

Parameters:

low - the low bound of the random number

high - the high bound of the random number

Returns:

a random number inbetween the given values (inclusive)

randomDimension

public static Dimension randomDimension(Integer low,
                                        Integer high)

Creates a random dimension where the height and width are between the given values (inclusive). The width and height are determined separately - meaning this will not always return a dimension where the width and height are the same.

Parameters:

low - the low bound of the width and height value

high - the high bound of the width and height value

Returns:

a random dimension where the height and width are values between low and high

randomDimension

public static Dimension randomDimension()

Creates a random dimension where the height and width are between the values MINIMUM_DIMENSION and MAXIMUM_DIMENSION (inclusive). This method is included to avoid the use of Integers in the calling code.

Returns:

a random dimension where the height and width are values between MINIMUM_DIMENSION and MAXIMUM_DIMENSION (inclusive).

randomPoint

public static Point randomPoint()

Creates a random dimension where the x and y coordinate are between the values MINIMUM_XY and MAXIMUM_XY (inclusive). This method is included to avoid the use of Integers in the calling code.

Returns:

a random point where the x and y coordinates are values between MINIMUM_XY and MAXIMUM_XY (inclusive).

randomPoint

public static Point randomPoint(Integer low,
                                Integer high)

Creates a random point where the x and y coordinates are between the given values (inclusive). The x and y coordinates are determined separately - meaning this will not always return a point where the x and y are the same. This version is used when you only specify one range. Should not be used if the x and y ranges are independent.

Parameters:

low - the low bound of the x and y value

high - the high bound of the x and y value

Returns:

a random point where the x and y coordinate values are between low and high

randomPoint

public static Point randomPoint(Integer lowX,
                                Integer highX,
                                Integer lowY,
                                Integer highY)

Creates a random point where the x and y coordinates are between the given values (inclusive). The x and y coordinates are determined separately - meaning this will not always return a point where the x and y are the same. This version is used when you want to vary the x and y ranges independently.

Parameters:

lowX - the low bound of the x coordinate value

highX - the high bound of the y coordinate value

lowY - the low bound of y coordinate value

highY - the high bound of the y coordinate value

Returns:

a random point where the x coordinate is between lowX and highX and the y coordinate value is between lowY and highY

randomSineMaker

public static SineMaker randomSineMaker()

Creates a random SineMaker

Returns:

a random SineMaker
