java random numbers code example

Example 1: java random number

import java.util.Random;

Random rand = new Random();

// Obtain a number between [0 - 49].
int n = rand.nextInt(50);

// Add 1 to the result to get a number from the required range
// (i.e., [1 - 50]).
n += 1;

Example 2: 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 3: 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 4: generate random number in java

import java.lang.Math;

int randomNumber;

int minimum = 1;
int maximum = 10 - minimum;

randomNumber = (int)((Math.random()*maximum) + minimum);

System.out.println("Random Number (Between 1-10): " + randomNumber);

Example 5: random numbers java

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

Example 6: how to generate random number in java

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