Implement the method countInitial which accepts as parameters an ArrayList of Strings and a letter, stored in a String. (Precondition: the String letter has only one character. You do not need to check for this.) The method should return the number of Strings in the input ArrayList that start with the given letter. Your implementation should ignore the case of the Strings in the ArrayList. Hint - the algorithm to implement this method is just a modified version of the linear search algorithm. Use the runner class to test your method but do not add a main method to your U7_L4_Activity_One.java file or your code will not be scored correctly.

Answer:

Answered below

Explanation:

//Program is implemented in Java

public int countInitials(ArrayList<string> words, char letter){

int count = 0;

int i;

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

if ( words[i][0]) == letter){

count++

}

return count;

}

//Test class

Class Test{

public static void main (String args[]){

ArrayList<string> words = new ArrayList<string>()

words.add("boy");

words.add("bell");

words.add("cat");

char letter = 'y';

int numWords = countInitials ( words, letter);

System.out.print(numWords);

}
