In Java, What Is The Method To Generate Random Integers Within A Specified Range?

To generate random integers within a specific range in Java, you can make use of the java.util.Random class.

Here’s an example code snippet:

import java.util.Random;

public class RandomNumberExample {
    public static void main(String[] args) {
        int min = 10;   // minimum value
        int max = 20;   // maximum value

        Random random = new Random();

        int randomNumber = random.nextInt(max - min + 1) + min;

        System.out.println("Random number between " + min + " and " + max + " is: " + randomNumber);
    }
}

In the above example, we first set the minimum value (min) and the maximum value (max) to generate a random number within the range [10, 20]. Then, we initialize an instance of the Random class.

To generate a random integer within the specific range, we use the nextInt() method of the Random class, specifying the range (max - min + 1) and add the minimum value (min) to the result. This will ensure that the generated random number falls within the desired range.

Finally, we print the random number using the System.out.println() statement. The output will be a random number between the specified range, for example: "Random number between 10 and 20 is: 15".
