make a random number generator class java code example
Example 1: 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 2: 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);
