Create a Java method that takes a String as input value and returns the number of vowels contained in that string.

Expert Solution

CODE:

import java.util.Scanner;

public class CountVowelsInString {
   //method to count number of vowels in a string
   public static int CountNumberOfVowels(String str){
       int vowelCount = 0; // the variable that holds the vowelCount

       // to loop through the string
       for (int i = 0; i < str.length(); i++) {
           char ch = str.toLowerCase().charAt(i);
           // if the character at the position is equal to any of the vowel
           if((ch=='a') || (ch=='e') || (ch=='i') || (ch=='o') || (ch=='u') ){
               vowelCount++; //increment the vowelCount
           }
       }
       //return statement
       return vowelCount;
   }

   public static void main(String[] args) {

       Scanner scan = new Scanner(System.in);// instantiating the Scanner class
       System.out.println("Please enter a string...");// prompt to enter a string
       String str = scan.nextLine();// getting the String input and storing into str
       int count = CountNumberOfVowels(str); // calling the method and getting the number of vowels

System.out.println(str + " has " + count + " number of vowels"); //writing the number of vowels
}
}

Write a recursive method using Java that takes a string s as input and returns a...

Write a recursive method using Java that takes a string s as input and returns a list that contains all the anagrams of the string s. An anagram is a word formed by rearranging the letters of a different word. For instance, the word ‘cat’ is an anagram of ‘act’. Notice that the output list cannot contain duplicates.

IN JAVA A recursive method that takes a String as its argument and returns a list of Strings which includes all anagrams of the String. This method will contain a loop that generates each possible substring consisting of all but one character in the input String, ie the substring that omits the first letter, then the substring that omits the second letter, etc. Within the loop, the method calls itself recursively for each substring. For each String in the list...

Write a Java method that takes an input string and computes the income minus the expenses....

Write a Java method that takes an input string and computes the income minus the expenses. The income components are indicated by numbers; while the expenses from your spending are numbers starting with a minus sign '-'. The input string may contain lowercase and uppercase letters, as well as other characters. Note that Character.isDigit(char) tests if a char is one of the chars '0', '1', ..., '9'. Also recall that Integer.parseInt(string) converts a string to an int. Test cases :...

Create a Java method findLongestPalindrome that takes a Scanner scn as its parameter and returns a...

Create a Java method findLongestPalindrome that takes a Scanner scn as its parameter and returns a String. It returns the longest token from scn that is a palindrome (if one exists) or the empty string (otherwise). (Implementation note: Use the built in isPalindrome method. This method calls for an optimization loop.) Where the isPalindrome Method takes a String s as a parameter and returns a boolean. It returns true if s reads the same forwards and backwards, i.e., is a...

Write a Java application with a JavaFXGUI that takes a String input by the user and shows whether the string contains all 26 letters of the (English version of the Latin) alphabet. For example, "Pack my box with five dozen liquor jugs" contains all 26 letters, but "The quick frown box jumps over the hazy log" does not contain a d. It does not matter whether one or more letters appear more than once. The GUI needs, at minimum, a...
