I Need to write a program based on the following Java program PercolationEstimation.java that uses both versions of percolation and computes the probability that a system percolates, but does not percolate directed downward. It will need N and p from the command line.

 

 

public class PercolationProbability {        

public static double evaluate(int n, double p, int trials) {   

     int count = 0;    

    for (int t = 0; t < trials; t++) {         

   boolean[][] isOpen = Percolation.random(n, p);      

      if (Percolation.percolates(isOpen))          

      count++;        }    

    return (double) count / trials;    }   

   public static void main(String[] args) {  

      int n = Integer.parseInt(args[0]);      

  double p = Double.parseDouble(args[1]);  

      int trials = Integer.parseInt(args[2]);       

double q = evaluate(n, p, trials);  

      StdOut.println(q);   

}

}
