Syntax

public double nextDouble()

Parameters

No parameter is required.

Return Value

Returns the next pseudorandom, uniformly distributed double value between 0.0 and 1.0 from this random number generator's sequence.

Exception

NA

Example:

In the example below, the java.util.Random.nextDouble() method is used to get pseudorandom number, uniformly distributed double value between 0.0 and 1.0.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating a random object
    Random rand = new Random();

    //printing uniformly distributed double random numbers
    for(int i = 0; i < 5; i++)
      System.out.println("Next Double Value: " + rand.nextDouble()); 
  }
}

One of the possible outcome is given below:

Next Double Value: 0.5086559355994734
Next Double Value: 0.13016283736554546
Next Double Value: 0.3692908714197346
Next Double Value: 0.24406924527560225
Next Double Value: 0.22947266175033265
