In this post we show how to generate random numbers using Java 8 features!If you would like to provide your source of random numbers you can do so and generate random integers in range with IntStream.generate() like here the Random class generates random integers, doubles, longs and so on, in various ranges.To generate a series of random numbers as a unit, you need to use a single Random object - do not create a newHere are some examples using Random. Example 1. import java.util.Random Java Create Random Color. AWT Components in Java, Button.The nextInt(255) method of Random class generates a random number between 0 to 255, the range required for a color component. Bullet Points : Internally it uses java.util.Random() to generate random numbers.As Math.random internally uses nextDouble method it will always return double number. In order to get int you have to cast the value to integer. 2- java.util.Random.
