Я написал этот фрагмент кода для имитации galton box для школьного проекта:

«‘ открытый класс GaltonBoxProject {

 public static void main(String[]args){

    //This will keep track of the final positions and will sort them

    int[] finalColumns = {0,0,0,0,0,0,0};

    //will track current pos of the ball

    //8 tiers

    //start from middle of the box

    int randChance;

    for(int a = 0; a < 100; a  ) {

        int currentPos = 3;

        for (int i = 0; i < 9; i  ) {

            //resets the number

            randChance = (int) (Math.random() * 100)   1;

            //if less than 50 go to the left

            //if 0 -->  

            //if 8 --> -

            if(currentPos == 0 amp;amp; randChance > 50) {

                currentPos  ;

            }

            else if (currentPos == 7 amp;amp; randChance <= 50) {

                currentPos--;

            }

            else if(currentPos != 7 amp;amp; currentPos != 0 amp;amp; randChance > 50){

                currentPos  ;

            }

            else if(currentPos != 7 amp;amp; currentPos != 0 amp;amp; randChance < 50){

                currentPos--;

            }

            //If you want to know why I got these results

            //I genuinely can't find the reason why this pattern happens

            //System.out.print(" RAND: "   randChance);

            //System.out.println(" POS: "   currentPos);

        }

        //Also debugging

        //System.out.println(a   " CURRENT POS: "   currentPos);

        //This will sort the numbers

        for(int k = 0; k < 7; k  ){

            if(k == currentPos){

                finalColumns[k]  ;

            }

        }

    }

    //for(int i = 0; i < 8; i   ) {

    //    System.out.println("KEY: "   finalColumns[i]);

    }

    for(int k = 0; k < 7; k  ){

        System.out.print(k   ": ");

        for(int j = 0; j < finalColumns[k]; j  ){

            System.out.print("*");

        }

        System.out.println("");

    }

}

Я получаю этот результат:

0: ********

1: ********

2: **********************

3: ***

4: ******************************

5: *****

6: *****************

Я должен получать колоколообразную кривую, и я не знаю, почему код делает это
