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.

Program below demonstrates the above mentioned function:

Program 1:

// program to demonstrate the
// function java.util.Random.nextGaussian()

import java.util.*;
public class GFG {
    public static void main(String[] args)
    {

        // create random object
        Random r = new Random();

        // check next Gaussian value and print it
        System.out.println("Next Gaussian value is = "
                           + r.nextGaussian());
    }
}

Output:

Next Gaussian value is = 0.3350871100964153

Program 2:

// program to demonstrate the
// function java.util.Random.nextGaussian()

import java.util.*;
public class GFG {
    public static void main(String[] args)
    {

        // create random object
        Random r = new Random();

        // check next Gaussian value and print it
        System.out.println("Next Gaussian value is = "
                           + r.nextGaussian());
    }
}

Output:

Next Gaussian value is = 1.5685150659018154
