We can use Random.nextInt() method that returns a pseudorandomly generated int value between 0 (inclusive) and the specified value (exclusive).. Below code uses the expression nextInt(max - min + 1) + min to generate a random integer between min and max. Random Class nextInt() method: Here, we are going to learn about the nextInt() method of Random Class with its syntax and example. It's correct, but as we can see, pretty unclear. The Random class nextInt method really does all the work in this example code. Below you can find example of generating 1000 integers in interval from 0 to 100: package In this post, we will see how to generate random integers between specified range in Java. Btw., it's a common trick for returning constrained random numbers. It can't be returned twice in a row as it can't be generated by random.nextInt(UPPER_BOUND - 1). 1. java.util.Random.
