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 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);
}
}
random number generator java
import java.util.Random;
class GenerateRandom {
public static void main( String args[] ) {
Random rand = new Random(); //instance of random class
int upperbound = 25;
//generate random values from 0-24
int int_random = rand.nextInt(upperbound);
double double_random=rand.nextDouble();
float float_random=rand.nextFloat();
System.out.println("Random integer value from 0 to" + (upperbound-1) + " : "+ int_random);
System.out.println("Random float value between 0.0 and 1.0 : "+float_random);
System.out.println("Random double value between 0.0 and 1.0 : "+double_random);
}
