For this assignment you are tasked with writing a command-line Java program that evaluates Reverse Polish notation (RPN) formulas. Here are the details: • Due date is as specified on the letter you received from the student office. ● Submission will be through the Moodle. Submit a file called Submission.java. This must be a Java program that: Correctly compiles under the UNIX command line (for optimal results, test your program or 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 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 ● • Other examples of NPN formulas are: 3 (result is 3) ● cd472$ javac Submission.java cd472$ echo 75 125 + | java Submission 200 ● 20 x (result is 0) 2 3+2 2 + x (result is 20) • 2 3 x 4 + (result is 10) • You can read more about RPN here:https://en.wikipedia.org/wiki/Reverse_Polish_notatic • As with all regular assignments you may NOT use any Java standard library class or method other than for input/output.

JAVA PROGRAM   Please Modify this program with further modifications as listed below: The program must pass the test case when uploaded to Hypergrade. ALSO, change the following in the program:  System.out.print("Enter a name (or 'QUIT' to exit): "); to: Enter a name to search or type QUIT to exit and take out this: System.out.println(filename + " is missing. Exiting..."); import java.io.*;import java.util.*;public class Main {    public static void main(String[] args) {        List<String> girlsNames = loadNames("GirlNames.txt");        List<String> boysNames = loadNames("BoyNames.txt");        Scanner scanner = new Scanner(System.in);        while (true) {            System.out.print("Enter a name (or 'QUIT' to exit): ");            String input = scanner.nextLine();            if (input.equalsIgnoreCase("QUIT")) {                break;            }            searchAndDisplay(input, girlsNames, boysNames);        }        scanner.close();    }    private static…

Using the Card.java class file, write a program to simulate a Deck of Cards. See Programming Project 8.7 (PP 8.7) from page 403 of your textbook (or view the attached image) for a description of what your program needs to do. Note that although the book description of the problem states that you should write the Card class, I do not want you to do that. You must use the Card file exactly as it is provided (NO modifications) and only write the DeckOfCards and Driver classes. public class Card{public final static int ACE = 1;public final static int TWO = 2;public final static int THREE = 3;public final static int FOUR = 4;public final static int FIVE = 5;public final static int SIX = 6;public final static int SEVEN = 7;public final static int EIGHT = 8;public final static int NINE = 9;public final static int TEN = 10;public final static int JACK = 11;public final static int QUEEN = 12;public final static int KING = 13; public final static int CLUBS = 1;public final static int DIAMONDS =…

Create a Java program that will let the user choose between organisers and volunteers. Then let them choose their work area (For example - California, Las Vegas, Washington DC, New York etc.) Then -1) Sign-up option is for organisers and volunteers to store their information (First Name, Last Name, User Name, E-mail, Phone Number, Password) in a text file. Also, store organizations name and how many times worked before to the organisers and volunteers section respectively. 2) Log in part is for authentication. Let the user input their username and password. If the username and password remain in the text file we've created in the Sign-up section, it will print "User successfully logged in". If there's not, it will print "Invalid Username and Password."NB- It will not use any graphical interface. Just basic java code. For clear exposure, a photo is attached.

Create a Java electronic voting program.  There should be 4 total parties(people you are able to vote for) use object oriented code and output your final result to a text file.
