For this assignment you are tasked with writing a command-line Java program that evaluates Reverse Polish notation (RPN) formulas. Here are the details: • This must be a Java program that: • Correctly compiles under the UNIX command line (for optimal results, test your program on Raptor). • When run from the command line your program must read from standard input an RPN formula. • You can assume there is a space between every operator and number. Every number will be a 32 bit integer. • Your program should be able to correctly handle the operations: +, -, x. • IMPORTANT: be careful that your program recognises precisely the three characters above (plus sign, minus sign, and the lowercase letter “x”, respectively). • Your program then should write to standard out a single line with the correct output in standard integer format. The following example shows correct behaviour for your program cd472$ javac Submission.java cd472$ echo 75 125 + | java Submission 200

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…

A place to buy candy is from a candy machine. A new candy machine is bought for the gym, but it is not working properly. The candy machine has four dispensers to hold and release items sold by the candy machine and a cash register. The machine sells four products — candies, chips, gum, and cookies—each of which is stored in a separate dispenser. You have been asked to write a program for this candy machine so that it can be put into operation. The program should do the following: Show the customer the different products sold by the candy machine Let the customer make the selection Show the customer the cost of the item selected Accept money from the customer Return change Release the item, that is, make the sale Note: java programming, please used given outline code   //Implement the blueprint of the Candy Machine import java.util.*; public class CandyMachine { // Each candy machine is made of 1 CashRegister and 4 Dispensers CashRegistercashRegister; Dispensercandy;…
