Create a recursive method, a method that calls itself, that returns the number of vowels that appear in any string given. Keep i

kvv77 [185]

<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));

Explanation:

//Bugs are highlighted in bold text

Declarations

private num invoiceNumber

private string customer

private num balanceDue

private num tax

public void setInvoiceNUMBER(num number)

Declarations

num LOW_NUM = 1000

if number > HIGH_NUM then

invoiceNumber = 0

else

if number < LOW_NUM then

invoiceNumber = 0

else

invoiceNumber = num

endif

return

return

public void setBalanceDue(num balance)

//Bug balanceDue is Invoice class varible

//but it is assigned to balance .it gives error

balance = balanceDue

setTax()

return

private void setTax()

Declarations

//Bug TAX_RATE is declared as string

//but assigned a double value

string TAX_RATE = 0.07

tax = tax * TAX_RATE

return

output "Invoice #", invoiceNumber

output "Customer: ", customer

output "Due: ", balanceDue

output "Tax: ", taxDue

//Invoice class has no variable called balance .it should be balanceDue

output "Total ", balance + taxDue
