Question

4 CS136: Computer Science II-Spring 2019 [10 points] Problem #4 A run is a sequence of adjacent repeated values. write a Java class (RunsPrinter. java) with one main method that generates a sequence of 20 random die tosses in an array (and not an ArrayList) and then prints the die values, marking the runs by including them in parentheses, like this: 1 2 (5 5) 3 124 3 (2 2 2 2) 3 6 (5 5) 6 3 1 Examples of program output: 2(33)56(22) (11) (4444)6142(33)1 (55)43(11)53415152153153 1636(11)46312362565345 Make sure that your code compiles and runs without errors when the following commands are used For compilation javac RunsPrinter.java For execution: java RunsPrinter Hint: Use the following pseudocode algorithm: Set a boolean variable inRun to false. For each valid index i in the ArrayList 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 )

Java Code:

import java.io.*;
import java.util.*;
import java.util.Random;
public class Runsprinter {
public static void main(String args[]) {
Random rand = new Random();
int n;
//declaring ArrayList with initial size n
ArrayList<Integer> arrli = new ArrayList<Integer>(20);
  
// Appending the new element at the end of the list
for (int i=0; i<20; i++){
n = rand.nextInt(6) + 1;
arrli.add(n);
}
// Printing elements
System.out.println(arrli);
//Given algorithem starated from here
boolean inRun = false;
for(int i = 0; i < 20; i++)
{
if(inRun){
if(arrli.get(i) != arrli.get(i-1)){
  
System.out.print(")");
inRun = false;
}
}
if(!inRun && i < 19){
if(arrli.get(i) == arrli.get(i+1)){
System.out.print("(");
  
inRun = true;
}
}
System.out.print(arrli.get(i));
}
}
}
