random number generator java from given amount code example
Example 1: 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);
}
}
Example 2: generate random number java
// JAVA - WITH A RANGE
(Math.random() * ((max - min) + 1)) + min
