Random nextGaussian() method in Java with Examples

The nextGaussian() method of Random class returns the next pseudorandom, Gaussian(normally) distributed double value with mean 0.0 and standard deviation 1.0 from the random number generator’s sequence.

Syntax:

public double nextGaussian()

Parameters: The function does not accepts any parameter.

Return Value: This method returns the next pseudorandom Gaussian distributed double number with mean 0.0 and standard deviation 1.0.

Exception: The function does not throws any exception.
