How to generate random floating point number in Java

In this tutorial, we use the java.util.Random() class to generate the random floating-point numbers by using the nextFloat() method.

Click here, to learn more about the java.util.Random() class with nextFloat() method.

Code with Explanation

import java.util.Random;

public class RandomFloatNumbers {
    public static void main(String[] args) {
        Random randomObj = new Random();
        System.out.println("The generated Random Floating Number is ");
        System.out.println(randomObj.nextFloat());
    }
}
Output
The generated Random Floating Number is 
0.23058897
  • Line number 5, here we create an object of Random class named as randomObj.
  • Line number 7, using the randomObj we call the nextFloat() method which returns the random floating-point number.

This is enough for a quick glimpse into random floating number generation in Java. If you need to learn more about the Random class then you can click the given link above the code.
