random integer 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: java random numbers in specific range
import java.util.Random;
Random rand = new Random();
int random_integer = rand.nextInt(upperbound-lowerbound) + lowerbound;
Example 3: random number in range java
(int)(Math.random() * ((max - min) + 1)) + min
Copy
Example 4: 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 5: Random number generator in java
public class RandomMethodExample
{
public static void main(String[] args)
{
System.out.println(Math.random());
System.out.println(Math.random());
}
}
Example 6: java random number generator in range
int rand = ThreadLocalRandom.current().nextInt(x,y);
