Write a program that takes as input an arithmetic expression. The program outputs whether the expression contains matching grouping symbols. For example, the arithmetic expressions {25 + (3 – 6) * 8} and 7 + 8 * 2 contains matching grouping symbols. However, the expression 5 + {(13 + 7) / 8 - 2 * 9 does not contain matching grouping symbols.

in java Strings itemToFind and inputItem are read from input. Integer wordCount is initialized with 1. Write a while loop that iterates until inputItem is equal to "Done". In each iteration of the loop: Increment wordCount if inputItem is equal to itemToFind. Read string inputItem from input.   Click here for example         Note: Assume that input has at least two strings. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19     import java.util.Scanner;   public class SimpleWhileLoop { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); StringitemToFind; StringinputItem; intwordCount;   itemToFind=scnr.next(); inputItem=scnr.next();   wordCount=1;   /* Your code goes here */   System.out.println(itemToFind+" occurs "+wordCount+" time(s)."); } }

In the classic problem FizzBuzz, you are told to print the numbers from 1 to n. However,when the number is divisible by 3, print "Fizz''. When it is divisible by 5, print "Buzz''. When it isdivisible by 3 and 5, print"FizzBuzz''. In this problem, you are asked to do this in a multithreaded way.Implement a multithreaded version of FizzBuzz with four threads. One thread checks for divisibilityof 3 and prints"Fizz''. Another thread is responsible for divisibility of 5 and prints"Buzz''. A third threadis responsible for divisibility of 3 and 5 and prints "FizzBuzz''. A fourth thread does the numbers.

Design a program that simulates the slot machine game. When the program starts, it should greet user and then start the game. For each game, the program asks user for the bet amount, and then randomly picks three words/images. If all the three words/images are same, user won three times of the bet amount, if any two of them are same, user won twice of the bet amount, otherwise, user won 0. The program should allow user to play as many games as wanted at one run. The program should display number of games user played, total amount bet and won at the end the program. It should also display each game's information, including game number, bet amount, the three words/images, and won amount.  Here is the list of words you may use: Cherries, Oranges, Plums, Bells, Melons, and Bars. i need to do this in raptor flowchart
