How do you generate a random number between 1 to 10 in Java?
Using random. nextInt() to generate random number between 1 and 10
- randomGenerator.nextInt((maximum – minimum) + 1) + minimum. In our case, minimum = 1. maximum = 10so it will be.
- randomGenerator.nextInt((10 – 1) + 1) + 1.
- randomGenerator.nextInt(10) + 1.
How do you guess a number in Java?
