write a method called luckyAs that takes any array of string

Solution

// LuckyCharacter.java
// counts frequency of capital A in string Array

import java.util.Scanner;

public class LuckyCharacter
{
    public static int LuckyAs(String[] str)
    {
        char ch;
        char c =\'A\';
        int count=0;

        for(int i=0; i<str.length; i++)
        {
            for (int j = 0;j < str[i].length();j++ )
            {
                ch = str[i].charAt(j);
                if(ch == c)
                {
                    count++;
                }
            }
          
        }
        return count;
    }
   public static void main(String args[])
   {
        Scanner scan = new Scanner(System.in);
        int totalString = 3;
      
        String[] str = new String[totalString];
        str[0] = \"Aloo\";
        str[1] = \"BArAk\";
        str[2] = \"BlAck Olives\";

        System.out.println(\"The character A has occurred for \" + LuckyAs(str) + \" times\");
      
   }
}

/*
output:

The character A has occurred for 4 times

*/
