JavaMathclass can be used to generate a random number within the specified range. Here, we use therandom()method of theMathclass to get a random number. See the example below. publicclassSimpleTesting{publicstaticvoidmain(String[]args){intmin_val=10;intmax_val=100;doublerandomNum=Math.rando...

How can I generate random integers in a specific range with Java?Brian L. Gorman
To generate a random integer within a specific range in Java, you can use the nextInt method of the Random class. This method returns a random integer from the Random object's sequence within the range specified by its arguments. Here's an example of how you can use the nextInt ...
This method takes an argument representing the upper bound of the random numbers to be generated. By adjusting this bound, we control the range of potential outcomes. Here’s an example: import java.util.Random; public class RandomNumberGenerator { public static void main(String[] args) { ...
import java.util.Random; /*from w ww . java 2s .co m*/ public class Main { public static void main(String[] args) { String[] arr = { "A", "B", "C", "D" }; Random random = new Random(); int select = random.nextInt(arr.length); System.out.println("Random String selecte...
Let’s assume we want to generate a random integer between 0 and 10, can we do this? Yes! In java, we can get a specific range of values using the Math.random() method, and to do so, all we need to do is multiply the returned value of the Math.random() method with the specif...
