program mencari luas persegi panjang dengan java



import java.util.Scanner;
public class LuasPersegiPanjang
{
 public static void main (String [] args)
 {
 Scanner nilai = new Scanner(System.in);
  int min,max;
  System.out.print("nilai minimal  = ");
  min = nilai.nextInt();
  System.out.print("nilai maksimal = ");
  max = nilai.nextInt();
  if (max < min)
  {
  System.out.println("nilai maksimal harus lebih besar dari nilai minimal = ");
  System.out.print("nilai maksimal = ");
  max = nilai.nextInt();
  }
  double panjang = min + Math.random () * (max - min + 1);
  double lebar = min + Math.random () * (max - min + 1);
  panjang = (int)panjang;
  lebar = (int)lebar;  
  System.out.println("Luas Persegi panhang = Panjang x lebar");
  System.out.println("\t\t     =" +((int)panjang)+" x "+((int)lebar));
  System.out.println("\t\t     ="+((int)(panjang * lebar)));
  
 }
}
