How do you write a random class in Java?

Method 1: Using random class

1. Import the class java.util.Random.
2. Make the instance of the class Random, i.e., Random rand = new Random()
3. Invoke one of the following methods of rand object: nextInt(upperbound) generates random numbers in the range 0 to upperbound-1 . nextFloat() generates a float between 0.0 and 1.0.

## Can Math random give 0?

Math. random() can never generate 0 because it starts with a non-zero seed. Set the seed to zero, the function does not work, or throws an error. A random number generator always returns a value between 0 and 1, but never equal to one or the other.
