How to generate Java random float between o and 1

Question

Problem:

Hello mate

I am in deep trouble. I want to generate a random float between 0 and 1 in a java program. What is the procedure to generate a random float number? Please share your thoughts on this.

Thanks in advance.

Answer 1

There is a built-in class in java name java.util.Random. The nextFloat() is a method of that class. It generates a random float between 0.0 (inclusive) to 1.0 (exclusive). Let’s use the class and its method to generates random float number in a java program

import java.util.Random;
public class MyClass {
   public static void main(String[] args) {
      Random obj = new Random();
      System.out.println(obj.nextFloat());
   }
}

The output I got
