Write a method called makeLine. The method receives an int parameter that is guaranteed not to be negative and a character. The

method returns a String whose length equals the parameter and contains no characters other than the character passed. Thus, if the makeLine(5,':') will return ::::: (5 colons). The method must not use a loop of any kind (for, while, do-while) nor use any String methods other than concatenation. Instead, it gets the job done by examining its parameter, and if zero returns an empty string otherwise returns the concatenation of the specified character with the string returned by an appropriately formulated recursive call to itself.

Answer:

public static String makeLine (int n, char c) {

   if (n ==0)

return "";

   else

       return (c + makeLine(n-1, c));

}

Explanation:

Create a method called makeLine that takes two parameters, int n and char c

If n is equal to 0, return an empty string

Otherwise, call the method with parameter n decreased by 1 after each call. Also, concatenate the given character after each call.

For example, for makeLine(3, '#'):

First round -> # + makeLine(2, '#')

Second round -> ## + makeLine(1, '#')

Third round -> ### + makeLine(0, '#') and stops because n is equal to 0 now. It will return "###".

<h2>Answer:</h2>

//Define the method as noOfVowels

   //Let it receive the string to be checked as argument

   public static int noOfVowels(String string){

   

       //Check the length of the string

       

       //If it is less than 1, then it is an empty string

       //Hence return 0

       if(string.length() < 1){    

           return 0;

       }

       

       //Else,

       else{

           //get the character at the first position in the string

           //and convert it to a lower case

           char x = string.toLowerCase().charAt(0);

           //Check if the character is a vowel

           if (x == 'a' || x == 'e' || x == 'i' || x == 'o' || x == 'u'){

               //if it is a vowel, add 1 to a recall of the method.

               //But this time, call the method with  

               //the string excluding the first character.

               //i.e the substring of the string starting at index 1 rather than 0

               return 1 + noOfVowels(string.substring(1));

           }

           

           else {

               //If it is not a vowel, just recall the method with

               //the string excluding the first character

               //i.e the substring of the string starting at index 1 rather than 0

               return noOfVowels(string.substring(1));

           }

       }

   }

The code has been written in Java and it contains comments explaining every part of the code. Please go through the comments carefully.

The actual lines of code have been written in bold face to distinguish them from comments.

The code is re-written without comments as follows;

   public static int noOfVowels(String string){

   

       if(string.length() < 1){    

           return 0;

       }

       

       else{

           char x = string.toLowerCase().charAt(0);

           if (x == 'a' || x == 'e' || x == 'i' || x == 'o' || x == 'u'){

               return 1 + noOfVowels(string.substring(1));

           }

           

           else{

               return noOfVowels(string.substring(1));

           }

       }
