This article is part of the “Java – Back to Basic” series here on Baeldung. 1. Generate an Unbounded Long Math.random() to Generate Random Numbers Between 1 to 10 ThreadLocalRandom.current.nextInt() to Generate Random Numbers Between 1 to 10 We will look at the steps to generate a random number between 1 and 10 randomly in Java. The Java Math.random() method returns a random value that is greater than or equal to 0.0 and less than 1.0. In this tutorial, we will learn about Math.random() method with the help of examples. Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, PHP, Python, Bootstrap, Java and XML. Don't know if any changes have been made to Math.random() recently but I have read advice from one author to use the java.util.Random class instead of Math.random() as the latter has a flaw in its algorithm.-----Junilu Lacar Sun Certified Programmer for the Java 2 Platform 66: * 67: * For simple random doubles between 0.0 and 1.0, you may consider using 68: * Math.random instead. 69: * 70: * @ see java.security.SecureRandom 71: * @ see Math#random() 72: * @ author Jochen Hoenicke 73: * @ author Eric Blake (ebb9@email.byu.edu) 74: * @status updated to 1.4 75: */ 76: public class Random implements Serializable 77: { 78: /** 79: * True if the next nextGaussian is Random MethodThe JavaScript Math.random() method is an excellent built-in method for producing random numbers.
