Problem with array

[Michael12]

Well, I have this code:

import java.io.*;
import java.util.Random;

class bekap{

  public static void main(String args[]){

    int Niz []= new int[10000];
    double a=0;
    double b=0;
    double v=0;
    double g=0;
    double H;

    Random rand = new Random();

    for(int i =0;i<10000;i++) {
      int probbability = (int) (100*rand.nextDouble());
      if (probbability< 25){
        Niz=2;
        a++;
      }else if (probbability<50){
        Niz=3;b++; 
      }else if (probbability<75) {
        Niz=5;
        v++;
      }else {
        Niz=6;
        g++;
      } 
    }
    H=(a/10000)*Math.log(1/(a/10000))/Math.log(2)+(b/10000)*Math.log(1/(b/10000))/Math.log(2)+(v/10000)*Math.log(1/(v/10000))/Math.log(2)+(g/10000)*Math.log(1/(g/10000))/Math.log(2);
    System.out.println("Entropia  input sequence is:"+H);
  }
}

My problem is how to count( in this sequency) 22, 33, 55,66, 222,333,555,666.

I really don't know what you're trying to do.

[teknomage1]

So you want to start with 2,3,5,6 and keep concatenating longer strings of them so that the sequence always matches 2*,3*,5*,6* ?

Well, I have this problem. I want to generate a pseudo-random array. The array consist of digits {2,3,5,6}. The probability apperance of digit 2 in this array is 0.25=25%. The probability apperance of digit 3 in this array is 0.25=25%, the probability apperance of digit 5 in this array is 0.25=25%,and probability of aopperance digit 6 in this array is 0.25=25%. When I created this random array, I want to know a score of digits 2 in this array, a score of digits 3 in this array, a score of digits 5 in this array, a score of digits 6 in this array. Also, in this pseudo-random array, I want to know score of apperance two digits 2 jointly. Also, I want to know a score of apperance two digits 3 jointly. Also,I want to know a score of apperance two digits 5 jointly. Also,I want to know a score of apperance two digits 6 jointly.

For example: I have a pseudo random array like this:

2 3 2 5 5 5 5 5 5 6 3 3 5 3 3 3 6 2 2 5 6 3 3....

The score of two digits 2 jointly in this array is:1.
The score of two digits 3 jointly in this array is:3.
The score of two digits 5 jointly in this array is: 3.
The score of two digits 6 jointly in this array is:0.

When I finished this,I want to know a score apperance a three digits 2 jointly, a three digits 3 jointly, a thre digits 5 jointly and a three digits 6 jointly in this rendom array.

In my example:
- score of three digits 2 jointly is 0.
- score of three digits 3 jointly is 1.
-score of three digits 5 jointly is 2.
-score of three digits 6 jointly is 0.


Best regards.
