public int choose(int numChoices)- Returns:
- random number between 0 and numChoices-1
-
next
public int next()Generate next value.- Specified by:
next
in interfaceSequenceGenerator
- Returns:
- next value in sequence.
-
getNext
public int getNext()- Specified by:
getNext
in interfaceSequenceGenerator
- Returns:
- next value in sequence.
-
setNext
public void setNext(int next)Set next value in sequence.- Specified by:
setNext
in interfaceSequenceGenerator

- seed set by setSeed.
-
reset
public void reset()Reset sequence generator so that it will restart at beginning.- Specified by:
reset
in interfaceSequenceGenerator
-
getMinimum
public int getMinimum()- Returns:
- minimum value returned by next().
-
setMinimum
public void setMinimum(int minimum) -
getMaximum
public int getMaximum()- Returns:
