Hopefully, you found this post interesting and useful. In this post, we learned how to generate random numbers between 1 and 10 in Java using the Random class and the Math class.Įither way works, it just depends on how you want to use it or what kind of data type you want in return. We have to cast it to an int because the Math.random() method returns a float, even though we want an int. Int value = (int) (Math.random() * (max - min)) + min Syntax Math.random() Return value A floating-point, pseudo-random number between 0 (inclusive) and 1 (exclusive). This is useful because we just need to do a simple multiplication to get a random number between 1 and 10. This class contains a random() method that returns a random float between 0 and 1. Using Math classĪnother way to generate random numbers is to use the Math class. Because we don't actually want 0 to ever be generated if we want numbers between 1 and 10, we need to add 1 to the result, in our case, min. The program should use a loop that repeats until the user correctly guesses the random number. The parameter of the nextInt method is the maximum value that can be generated, and it includes 0. If the user’s guess is lower than the random number, the program should display Too low, try again. Int value = random.nextInt(max + min) + min Simply import the package and use the nextInt method: import This class is built-in to Java, so you don't need to use a third-party library to use it. The rand( ) function generates random numbers between 0 and 1 that are distributed uniformly (all numbers are equally probable). The recommended way to use random is to create a new instance of the Random class, and then use the instance to generate random numbers. In this post, we will learn how to generate random numbers between 1 and 10 in Java. You can use randomness in programming to simulate dice rolls, lottery tickets, and other random events. You can still calculate random number between 1 to 10 or between any number by using Math.random () method. Math.random() used with Math.floor() can be used to return random integers. Randomness is useful in programming for many things. Math.random() always returns a number lower than 1.
