Answers for "random integer in java"

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;

java random numbers in specific range

import java.util.Random;

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

random number in range java

Random number generator in java

// java.util.random example
import java.util.Random;
public class JavaRandomClass
{
   public static void main(String[] args)
   {
      Random random = new Random();
      // random integers in range 0 to 999 
      int randInt1 = random.nextInt(1000); 
      int randInt2 = random.nextInt(1000);
      // printing random integers
      System.out.println("Random Integers: " + randInt1); 
      System.out.println("Random Integers: " + randInt2);
      // here we are generating Random doubles
      double randDou1 = random.nextDouble(); 
      double randDou2 = random.nextDouble();
      // printing random doubles
      System.out.println("Random Doubles: " + randDou1); 
      System.out.println("Random Doubles: " + randDou2);
   }
}
