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;

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);
    }
}

random numbers java

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

java get random

// Thread safe random number generator.

import java.util.concurrent.ThreadLocalRandom;



// Generate random integers  
int val = ThreadLocalRandom.current().nextInt();  

// Print random int
System.out.println("Random Integer: " + val); 

java random number

how to generate random number in java

import java.util.Random;

Generate Random number using Math.random in Java

class GenerateRandom {
    public static void main( String args[] ) {
      int min = 50;
      int max = 100;
        
      //Generate random int value from 50 to 100 
      System.out.println("Random value in int from "+min+" to "+max+ ":");
      int random_int = (int)Math.floor(Math.random()*(max-min+1)+min);
      System.out.println(random_int);
    }
}

Java random number generator

Random random = new Random();
long v1 = random.nextInt();
long v2 = random.nextInt();
for (int i = 0; i < 65536; i++) {
    long seed = v1 * 65536 + i;
    if (((seed * multiplier + addend) & mask) >>> 16) == v2) {
        System.out.println("Seed found: " + seed);
        break;
    }
}

java random

import java.util.Random;
//If there is a need to reproduce the same sequence of random numbers, 
//we have to specify a seed to the constructor, like 100000
Random random = new Random(100000);    //using a seed
System.out.println(random.nextInt(5)); // print one random 0, 1, 2, 3, 4
System.out.println(random.nextInt(5));
