Chapter 4, Problem 4.26PE
(Financial application: monetary units) Rewrite Listing 2.10, ComputeChange.java, to fix the possible loss of accuracy when converting a float value to an int value. Read the input as a string such as "11.56". Your program should extract the dollar amount before the decimal point, and the cents after the decimal amount using the indexOf and substring methods.

(Emirp) An emirp (prime spelled backward) is a nonpalindromic prime number whose reversal is also a prime.
For example, 17 is a prime and 71 is a prime, so 17 and 71 are both emirps. Write a Java program that displays
the first 100 emirps. Display 10 numbers per line with a spacing of 5; all numbers should be left-aligned.

CPU Usage
We have the hourly average CPU usage for a worker's computer over the course of a week. Each row of data represents a day of the week starting with Monday. Each column of data is an hour in the day starting with 0 being midnight.
Create a chart that shows the CPU usage over the week. You should be able to answer the following questions using the chart:
When does the worker typically take lunch?
Did the worker do work on the weekend?
On which weekday did the worker start working on their computer at the latest hour?

Write a program that will help an elementary school student learn multiplication. Use a Random object to produce two positive one-digit integers. The program should then prompt the user with a question, such as How much is 6 times 7? The student then inputs the answer. Next, the program checks the student’s answer. If it’s correct, display the message "Very good!" and ask another multiplication question. If the answer is wrong, display the message "No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. A separate method should be used to generate each new question. This method should be called once when the application begins execution and each time the user answers the question correctly.arrow_forward(Written in Java or Python) Write a program that allows a user to select 3 points on a graphics panel.

Do not draw the randomly generated point. Allow the user to repeat the process without removing the old dots. Allow the user to clear the screen.arrow_forward
- DO NOT USE EXISTING ANSWERS ON CHEGG OR COURSE HERO OR ANY OTHER SERVICES PLEASE! Thanks :) CODE IN PYTHON AND SHOW COMMENTS TO EXPLAIN CODE A confused Dutchman trying to speak English could say “I am in the war”, even though there is no hostile activity going on. The confusion1 here is that the English sentence “I am confused” is translated in Dutch as “Ik ben in de war”, which is phonetically (“sounding”) quite close to the first sentence. Such confusion leads to much enjoyment, but can complicate matters a bit. Given a sentence in Dutch and a dictionary containing both correct translations as well as phonetic (incorrect) translations of individual words, find the translation of the sentence and indicate whether it is correct, or in case there is more than one find the total number of correct and incorrect translations. A sentence is correctly translated when each word of the sentence is correctly translated.

Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 import java.util.Scanner; public class LabProgram {public static void main(String[] args) {/* Type your code here. */}}arrow_forward
