given a number n for each integer i in the range from 1 to n inclusive stakoverflow in java code example

Example 1: how to get random number in java in range

package com.mkyong.example.test;

import java.util.Random;

public class TestRandom {

    public static void main(String[] args) {

        for (int i = 0; i < 10; i++) {
            System.out.println(getRandomNumberInRange(5, 10));
        }

    }

    private static int getRandomNumberInRange(int min, int max) {

        if (min >= max) {
            throw new IllegalArgumentException("max must be greater than min");
        }

        Random r = new Random();
        return r.nextInt((max - min) + 1) + min;
    }

}

Example 2: how to generate random numbers in java within range

import java.util.Random;

Random rand = new Random();
int random_integer = rand.nextInt(upperbound-lowerbound) + lowerbound;
