Create the Java function to receive an ArrayList object The

Create the Java function to receive an ArrayList object. The function will count all of the single-digit positive numbers in the array and return that total.

Solution

CountSingleDigit.java

import java.util.ArrayList;


public class CountSingleDigit {

  
   public static void main(String[] args) {
       ArrayList<Integer> list = new ArrayList<Integer>();
       list.add(11);
       list.add(112);
       list.add(1);
       list.add(1441);
       list.add(1155);
       list.add(6);
       list.add(81);
       list.add(8);
       list.add(3);
       list.add(111111);
       int count = getSinglDigitCount(list);
       System.out.println(\"Count = \"+count);

   }
   public static int getSinglDigitCount(ArrayList<Integer> list){
       int count = 0;
       for(int i=0; i<list.size(); i++){
if(list.get(i) >=0 && list.get(i) <= 9){
               count++;
           }
       }
       return count;
   }

}

Output:

Count = 4
