Student name: CIS 232 Introduction to Programming Homework Assignment 10 Due Date:  11/23/2020 Instructor: Dr. Lomako Problem Statement:  Write a Java program with the main method and a multiplication method (must be created, not the library method).     Create “HW10_lastname.java”  program that:   Prints a program title Creates two n x n square matrices A and B and initializes them with random values Displays the matrices A and B Calls the multiplication method that multiplies two square matrices and returns a                matrix AB that is the result of the multiplication. Prints AB matrix

Computer Science Part C: Interactive Driver Program Write an interactive driver program that creates a Course object (you can decide the name and roster/waitlist sizes). Then, use a loop to interactively allow the user to add students, drop students, or view the course. Display the result (success/failure) of each add/drop.

A dual-tone multi-frequency (DTMF) system is used to produce signals that represent the dialed digits in a telephone system. A combination of a horizontal frequency and a vertical frequency is produced whenever a button is pressed on the keypad. The figure below shows a telephone keypad and the different frequencies used. 697 Hz 770 Hz 852 Hz 941 Hz 1209 Hz 1 4 7 1336 Hz 2 1477 Hz 3 5 6 8 9 # 0 * Generate the DTMF tone decoder that will take an audio file the DTMF signal of your student number. The student number must be presented as one complete string (e.g. 2020123456)

Java Calculating the User's Sum Write a complete program that reads in numbers and calculates the sum of the numbers in that range. Code Specifications In the main method, read input from the user. Read in two integers from the user: a lower end of the range and an upper end of the range. Check if the numbers are valid: the lower number cannot be greater than the upper number. If the numbers are invalid, use a loop to ask for new numbers. Continue looping until you get two valid values. Write a method called calculateTheSum.  The method takes in a lower and upper end of the range. The method calculates the sum of all values from lower (inclusive) to upper (inclusive). Invoke the method from main the output the result. Test Cases I recommend testing your code using the test cases below. I've listed the user inputs along with a sample of the result. User Inputs Result lower = 10, upper = 1 the program should ask for new input lower = 5, upper = -5 the program should ask…

Integer userValue is read from input. Assume userValue is greater than 1000 and less than 99999. Assign tensDigit with userValue's tens place value. Ex: If the input is 15876, then the output is: The value in the tens place is: 7 2 3 public class ValueFinder { 4 5 6 7 8 9 10 11 12 13 GHE 14 15 16} public static void main(String[] args) { new Scanner(System.in); } Scanner scnr int userValue; int tensDigit; int tempVal; userValue = scnr.nextInt(); Your code goes here */ 11 System.out.println("The value in the tens place is: + tensDigit);

ShowCurrentTime.java an example program in Chapter, gives a program that displays the current time in GMT. Common old news shows would show clocks across many time zones, write a program that modifies ShowCurrent Time and will display the time in prominent business centers. London, Paris, New York was common. Write a program that displays the time in: Berlin, London, New York, Chicago, San Francisco, Tokyo and Hong Kong. ↓ HONG KONG ↓ LONDON L PARIS TOKYO MOSCOW 101 BERLIN DUBAI iStock Credit: Tetlana Muslyaka NEW YORK

Discrete Mathematics: Assignment details:  Replace all the 0 (Zero) digits in your ID by 4. Example: If your ID is 38104680, it becomes 38144684 Take the first 6 digits and substitute them in this expression (( A + B) / C) * ((D-E)/F)-2) according to the following table;                                                            Letter Replace by Digit Example Digit A 1st 3 B 2nd 8 C 3rd 1 D 4th 4 E 5th 4 F 6th 6   After substitution your expression will be similar to this (( 3 + 8) / 1) * ((4-4)/6)-2). Draw a rooted tree that represents your expression.                              What is the prefix form of this expression.                   3.What is the value of the prefix expression obtained in step 2 above?
