randomInt

int randomInt(int min,
              int max)

Returns a random integer greater than or equal to min and less than or equal to max.

randomDouble

double randomDouble(double min,
                    double max)

Returns a random double greater than or equal to min and less than or equal to max.

randomVel

java.awt.Point randomVel(java.awt.Rectangle rect)

Returns a random velocity (as a Point) subject to the constraint that the absolute value of the vleocity (speed) is less than maxV.

randomDim

java.awt.Dimension randomDim(java.awt.Dimension maxDim)

Returns a random square Dimension, whose width is maxDim.width/2<=width<=maxDim.width

randomBounds

java.awt.Rectangle randomBounds(java.awt.Rectangle rect,
                                java.awt.Dimension maxDim)

Generates a randomly located and sized rectangle

randomColor

java.awt.Color randomColor()
