How do I generate random integers within a specific range in java? | Projectshop

Sure, here’s a step-by-step guide to generating random integers within a specific range in Java:

1. Import the Random class: First, you need to import the ‘Random‘ class from the ‘java.util‘ package. This class will help you generate random numbers.

import java.util.Random;

2. Create an instance of Random: Instantiate the ‘Random‘ class to use its methods for generating random numbers.

Random random = new Random();

3. Define the range: Determine the range within which you want to generate random numbers. Let’s say you want numbers between 1 and 100.

4. Generate the random number within the range: Use the ‘nextInt(int bound)‘ method of the ‘Random‘ class to generate a random integer within the specified range.

int min = 1;
int max = 100;
int randomNumber = random.nextInt(max - min + 1) + min;

This line of code generates a random number between ‘min‘ (inclusive) and ‘max‘ (inclusive).

Putting it all together, here’s the complete code:

import java.util.Random;

public class RandomNumberGenerator {
    public static void main(String[] args) {
        Random random = new Random();
        int min = 1;
        int max = 100;
        int randomNumber = random.nextInt(max - min + 1) + min;
        System.out.println("Random number between " + min + " and " + max + ": " + randomNumber);
    }
}

This code will output a random number between 1 and 100 each time it’s executed. Adjust the ‘min‘ and ‘max‘ variables to change the range as needed.
