Generate Random Float type number in Java

In order to generate Random float type numbers in Java, we use the nextFloat() method of the java.util.Random class. This returns the next random float value between 0.0 (inclusive) and 1.0 (exclusive) from the random generator sequence.

Declaration −The java.util.Random.nextFloat() method is declared as follows −

public float nextFloat()

Let us see a program to generate random float type numbers in Java.


 Live Demo

import java.util.Random;
public class Example {
   public static void main(String[] args) {
      Random rd = new Random(); // creating Random object
      System.out.println(rd.nextFloat()); // displaying a random float value between 0.0 and 1.0



Note − The output might vary on Online Compilers.
