Write a recursive method that counts the number of vowels in a string. It must return the number of vowels. Use appropriate parameters as needed. Hint: There's an ArrayList method called contains that might make checking whether a character is a vowel easier.
static int vowelCount(ArrayList<Character> list, int start){ if(start<list.size()){ char ch = list.get(start); if(ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' || ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U'){ return 1+vowelCount(list,start+1); } else{ return vowelCount(list,start+1); } } return 0; }

Java Program Write a recursive method that takes a string and return a string where every character appears twice. Output must match exactly as below: only two LL's since there is already two of the character For example, if the string is “HELLO”, it will return “HHEELLOO”. Write a program to test it. must be recursive!!!
java 2. Write a recursive method to return the number of occurrences a character c in a string s. c and s should be parameters.
In Java, write a program that prompts the user to input a sequence of characters and outputs the number of vowels. You will need to write a method to return a value called isAVowel which will return true if a given character is a vowel and returns false if the character is not a vowel. A second method, called isAConstant, should return true if a given character is a constant and return false if the character is not a constant....
‘C’ programming language question Write a MENU DRIVEN program to A) Count the number of vowels in the string B) Count the number of consonants in the string C) Convert the string to uppercase D) Convert the string to lowercase E) Display the current string X) Exit the program The program should start with a user prompt to enter a string, and let them type it in. Then the menu would be displayed. User may enter option in small case...
public static int countCharacter(String str, char c) { // This recursive method takes a String and a char as parameters and // returns the number of times the char appears in the String. You may // use the function charAt(int i) described below to test if a single // character of the input String matches the input char. // For example, countCharacter(“bobbie”, ‘b’) would return back 3, while // countCharacter(“xyzzy”, ‘y’) would return back 2. // Must be a RECURSIVE...
Write function vowelCount2() that takes a string as input and counts and prints the number of occurrences of vowels in the string. Vowels are a, e, i, o, and u. Implement the code in the file lab5.py. This function is very similar to the function of the problem 4.25, but the vowel information which did not appear in the string should not be printed. The printing order of the vowels is a, e, i, o, u. e.g.) >>> lab5.vowelCount2(‘augustana’) a,...
Programming: Write a SPIM assembly language program num-vowel.s based on the hardware implementation method in the lab notes and the above practice. The program will do the following: Prompt the user to enter a string. The program will call the procedure vowelp to check if a character entered in the string is a vowel or not. Count how many vowels and how many non-vowels are in the string. Print out the calculated results with appropriate message. Hint: A loop is...
/* Write a recursive function named editDistance that accepts two string * parameters and returns the "edit distance" between the two strings as an * integer. Edit distance (also called Levenshtein distance) is the minimum * number of "changes" required to get from s1 to s2 or vice versa. A "change" * is a) inserting a character, * b) deleting a character, or * c) changing a character to a different character. *...
MUST BE IN JAVA AND USE RECURSION Write a recursive method that returns the number of all occurrences of a given word in all the files under a directory. Write a test program. Use the following header: public static long findInFile(File file, String word)
Using Java only Implement a program that uses a recursive method to print a string backward. Your program must contain a recursive method that prints the string backward. Use appropriate parameters in your method.
