how to randomize numbers in java code example

Example 1: how to create a random number in java

import java.util.Random;

class scratch{
    public static void main(String[] args) {
        Random rand = new Random();
        System.out.println( rand.nextInt(5) );
        //prints a random Int between 0 - 4 (including 0 & 4);
    }
}

Example 2: how to generate a random number in java

import java.util.Random;

Random rand = new Random();
int maxNumber = 10;

int randomNumber = rand.nextInt(maxNumber) + 1;

System.out.println(randomNumber);

Example 3: how to generate random number in java

double x = (Math.random()*((max-min)+1))+min;

Example 4: random numbers java

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