Oct 5, 2012 · Loop through each character, test if they're equal to the vowels being sought; If they match, record the one that matched; For some guidance on loops, particularly on iterating over a String: https://stackoverflow.com/a/2451660/101095. The easiest way to for-each every char in a String is to use toCharArray(): for (char ch: "xyz".toCharArray()) { }

Oct 20, 2017 · The problem is that your loop will iterate until i = 5, even if a vowel is detected. We need a way to tell the loop to pretend that never happened. You can't decrement i, or you'll be stuck at the same character forever.

Nov 8, 2014 · You can do this with a do/while loop. The skeleton for this kind of loop looks like this: Scanner input = new Scanner(System.in); do { // do your stuff here System.out.println("Would you like to check another phrase in the Vowel Counter? if so Press 1 if not press 2"); } while(input.nextInt() == 1); System.out.println("Have a nice day");

Nov 9, 2011 · /* Program will allow user to repeatedly enter letters.Using a do-while loop and switch statement, the program will count the number of vowels entered until a full stop is entered. */ [code] import java.util.Scanner; public class VowelsEnteredUntilFullStop { public static void main(String[] args) {Scanner keyboardIn = new Scanner(System.in);

You can loop through A to Z using for loop because they are stored as ASCII characters in Java. So, internally, you loop through 65 to 90 to print the English alphabets. With a little modification, you can display lowercase alphabets as shown in the example below.

Nov 22, 2024 · Java while loop is a control flow statement used to execute the block of statements repeatedly until the given condition evaluates to false. Once the condition becomes false, the line immediately after the loop in the program is executed. Let's go through a simple example of a Java while loop: [GFGT

This program is a simple example of how to use a do-while loop in Java to iterate over a range of numbers. In this case, it is used to print out all even numbers between 2 and the user-specified limit.

The do/while loop is a variant of the while loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true. The example below uses a do/while loop.

Nov 9, 2011 · Scanner keyboardIn = new Scanner (System. in); char letter = 1, vowel, vowelCount =0, total =0; // declare variables System. out. println("Enter a letter: "); // get user input [B] letter = keyboardIn. nextInt();[/ B] do { System. out. println("Enter a letter: "); } while(letter != '.'); switch (total) { case 'a' : case 'e' : case 'i' :...

Nov 3, 2016 · The index in your for loop starts at 0, so this statement: String beforeText = userInput.substring(0, i-1) will throw a java.lang.StringIndexOutOfBoundsException if there is a vowel at the first index. You don't need the "else" case if you aren't doing anything inside it.
