Question

Exercise : Randomizer In this exercise, we are going to create a static class Randomizer that will allow users to get random integer values from the method nextInt() and nextInt(int min, int max). Remember that we can get random integers using the formula int randInteger = (int)(Math.random() * (range + 1) + startingNum). nextInt() should return a random value from 1 - 10, and nextInt(int min, int max) should return a random value from min to max. For instance, if min is 3 and max is 12, then the range of numbers should be from 3 - 12, including 3 and 12.

Answer 1

Answer:

Here the code is by using java.

Explanation:

//Randomizer.java

public class Randomizer {

public static int nextInt() {

//get random number from 1-10

int randInteger = (int) (Math.random() * (11) + 1);

//if number is greater than 10 or less than 1

while (randInteger > 10 || randInteger < 1) {

randInteger = (int) (Math.random() * (11) + 1);

}

return randInteger;

}

public static int nextInt(int min, int max) {

//formula to get random number from min-max

int randInteger = (int) (Math.random() * (max + 1) + min);

while (randInteger > max || randInteger < min) {

randInteger = (int) (Math.random() * (max + 1) + min);

}

return randInteger;

}

}

//RandomizerTester.java

public class RandomizerTester {

public static void main(String[] args) {

System.out.println("Results of Randommizer.nextInt()");

for (int i = 0; i < 10; i++) {

System.out.println(Randomizer.nextInt());

}

int min = 5;

int max = 10;

System.out.println("\n Results of Randomizer.nextInt(5,10)");

for (int i = 0; i < 10; i++) {

System.out.println(Randomizer.nextInt(min, max));

}

}

}

OUTPUT:
