Hi Friend,

Try the following code:

import java.util.*;

public final class RandomNumberBetweenTwoIntegers {

  public static final void main(String[] args){
    int min = 115;
    int max = 250;
    Random random = new Random();
     long range = (long)max - (long)min + 1;
    long fraction = (long)(range * random.nextDouble());
    int randomNumber =  (int)(fraction + min);    
   System.out.println(randomNumber);
 }
}

Thanks
