Write a program in Java to count the total number of vowels and consonants in a String. The string can contain all the alphanumeric and other special characters as well. However, only the lowercase English alphabets are allowed in the String.

Write a JAVA program that prints the following grid to play Tic-Tac-Toe. +--+--+- Declare string variables to hold two kinds of patterns: a comb-shaped pattern and the bottom line. print the comb three times and the bottom line once.

Write a program using java programing language. Write a Java class (called ShowNum) that displays the same number of asterisks (row and columns) as is input in 2 numbers. Your class should have a default constructor (number1 is 0, number2 is 0) and another constructor that inputs 2 numbers (integers). You'll need accessor methods for the numbers and a display method that displays as follows: Input: 2, 7 ******* ******* Demo the class in a client (called ShowNumClient) that allows the user to run the program as many times as they want (enter number and use display method). The user will signal with a sentinel (-1), when they want to terminate the client. Make sure that each number entered in the client is between 1 and 30.

Write a FULL Java procedural program for a simple word guessing game. Below is an example of the required program behaviour. The bold text is user keyboard input. The player is allowed to guess one letter or the whole word incorrectly up to 5 times; each incorrect guess is called a "strike". The program starts by displaying one full stop (’.’) for each character of the secret word. You may assume the word is hardcoded into the game, is in lower case, and is of length greater than one. In each round of the game, the game first checks if the player has reached the maxinum number of strikes; if so, the player loses and the game ends. If not, the game prints an input prompt. The player then guesses either one letter (by entering a single character) or the whole word (by entering multiple characters). If a single letter is guessed correctly, meaning the character occurs in the word, the game reveals the positions of those occurrences in the word and proceeds to the next round. If the whole...

Design a java program with an algorithm that will take a string from the user and then decide if each character in that string is unique. For example, if you ask the user to enter a string and that user enters the world ‘hello’, the result of the algorithm implementedshould return ‘false’ or ‘not unique’. If the user enters a string such as the word ‘phone’ the program will return ‘true’ or ‘unique’ since every character in the word phone is unique and is not repeated. An example of this program follows: Output should show as : enter a string rizma This string has all the unique characters would u like to continue?(y for yes n for no) y Enter a string waali This string is not unique

In JAVA language. Given a string jv = "JAVA", write a program such that the string to be printed in output should be "AVAJJAVA".

I need help with this Java problem as it's explained in the image below: Palindrome (Deque) A palindrome is a string that reads the same backwards and forwards. Use a deque to implement a program that tests whether a line of text is a palindrome. The program reads a line, then outputs whether the input is a palindrome or not. Ex: If the input is: senile felines! the output is: Yes, "senile felines!" is a palindrome. Ex: If the input is: rotostor the output is: No, "rotostor" is not a palindrome. Ignore punctuation and spacing. Assume all alphabetic characters will be lowercase. Special case: A one-character string is a palindrome. Hint: The deque must be a Deque of Characters, but ordinary chars will be automatically converted to Characters when added to the deque. Java Code: import java.util.Scanner; import java.util.LinkedList; import java.util.Deque; public class LabProgram { public static void main(String[] args) { Scanner scnr = new...
