Random nextDouble() method in Java with Examples

The nextDouble() method of Random class returns the next pseudorandom, uniformly distributed double value between 0.0 and 1.0 from this random number generator’s sequence.

Syntax:

public double nextDouble()  

Parameters: The function does not accepts any parameter.

Return Value: This method returns the next pseudorandom, uniformly distributed double value between 0.0 and 1.0 from this random number generator’s sequence.

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.nextDouble()

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

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

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

Output:

Next double value is = 0.10210556893379474

Program 2:

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

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

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

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

Output:

Next double value is = 0.26964189606000966
