Question

Write a program that prompts the user for the number n of die tosses, then calls a constructor with argument n. Your class should have a method which then generates a sequence of n random die tosses in an array and returns the array reference. Your main program then prints the die values, marking runs by including them in parentheses, like this:

1 2 (5 5) 3 1 2 4 3 (2 2 2 2) 3 6 (5 5) 6 3 1

Use the following pseudocode:

Set a boolean value inRun to false.
For each index i in the array {
If inRun {
if(values[i] is different from the preceding value{
print )
inRun = false
}
}
if not inRun {
if values[i] is the same as the following value{
      print (
inRun = true
}

}
print values[i]
}
If inRun, print )

I have ...... needs to be OOP java thanks

public class DieTosses {
   
public static void printRun(int[] values) {

boolean inRun = false;

int previousValue = values[0];

for (int i = 0; i < values.length - 1; i++) {

if (inRun) {

if (values[i] != previousValue) {

System.out.print(")");

inRun = false;

}

} else {

if (values[i] == values[i + 1]) {

System.out.print(" (");

inRun = true;

} else {

System.out.print(" ");

}

}

previousValue = values[i];

System.out.print(values[i]);

}

if (inRun && values[values.length - 1] == previousValue) {

System.out.print(" " + values[values.length - 1] + ")");

} else if (inRun && values[values.length - 1] != previousValue) {

System.out.print(") " + values[values.length - 1]);

} else {

System.out.print(" " + values[values.length - 1]);

}

}

public static int[] generateDieTosses(int n) {

int[] tosses = new int[n];

for (int i = 0; i < n; i++) {

tosses[i] = (int) (Math.random() * 6 + 1);

}

return tosses;

}

}

Explanation / Answer

Hi, Please find my implementation.

######### Dice.java ########

class Dice{

  

   private int tosses[];

   // constructor

   public Dice(int n){

       tosses = new int[n];  

       generateDieTosses();

   }

  

   private void generateDieTosses() {

       for (int i = 0; i < tosses.length; i++) {

           tosses[i] = (int) (Math.random() * 6 + 1);

       }

   }

  

   public int[] getTosses(){

       return tosses;

   }

}
