random numbers in java code example
Example 1: java random number
import java.util.Random;
Random rand = new Random();
int n = rand.nextInt(50);
n += 1;
Example 2: Random number generator in java
import java.util.Random;
public class JavaRandomClass
{
public static void main(String[] args)
{
Random random = new Random();
int randInt1 = random.nextInt(1000);
int randInt2 = random.nextInt(1000);
System.out.println("Random Integers: " + randInt1);
System.out.println("Random Integers: " + randInt2);
double randDou1 = random.nextDouble();
double randDou2 = random.nextDouble();
System.out.println("Random Doubles: " + randDou1);
System.out.println("Random Doubles: " + randDou2);
}
}
Example 3: 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) );
}
}
Example 4: 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 5: 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 6: random numbers java
int random = (int) (Math.random()*(max-min+1)+min);
