math.random java

// int rand = (int)(Math.random() * range) + min; 
// Java program to demonstrate Math.random() working 
// of java.lang.Math.random() method 
import java.lang.Math;

Generate Random number using Math.random in Java

class GenerateRandom {
    public static void main( String args[] ) {
      int min = 50;
      int max = 100;
        
      //Generate random int value from 50 to 100 
      System.out.println("Random value in int from "+min+" to "+max+ ":");
      int random_int = (int)Math.floor(Math.random()*(max-min+1)+min);
      System.out.println(random_int);
    }
}

maths.random in Java

double rand = (Math.random() * range) + min;

java math random
