All Known Implementing Classes:

public interface DoubleRandomGenerator

An interface for generating random double values.

The contract of this interface is that values returned by nextDouble() must be included between those returned by lowerDouble() and upperDouble().

Apart from that, those values can follow an arbitrary distribution, i.e. does not have to be uniformly distributed.

Method Summary

Modifier and Type	Method and Description
double	lowerDouble() Specifies the lower bound of the values that can be returned by nextDouble().
double	nextDouble() Returns a random double value arbitrarily distributed in the range [lowerDouble(), upperDouble()].
double	upperDouble() Specifies the upper bound of the values that can be returned by nextDouble().

Method Detail

nextDouble

double nextDouble()

Returns a random double value arbitrarily distributed in the range [lowerDouble(), upperDouble()].

Returns:

A random value.

lowerDouble

double lowerDouble()

Specifies the lower bound of the values that can be returned by nextDouble().

Returns:

This generator’s lower bound.

upperDouble

double upperDouble()

Specifies the upper bound of the values that can be returned by nextDouble().

Returns:

This generator’s upper bound.
