Writing A Program That Determines If Number Is Palindrome Or Not
Apr 3, 2015I'm in the process of writing a program that determines if a number is a Palindrome or not. I'm not allowed to use strings and am required to use the getSize method shown below. I believe my issue that I'm having is that the "num" is not being called in the getSize method, and therefore not running the while loop, or at least that is what I believe is the issue.
import javax.swing.*;
public class getSize{
public static void main( String[] args )
{
int num;
num = Integer.parseInt (JOptionPane.showInputDialog ( "Please input a number" ));

How To Make A Method That Find Highest Value In Array
Dec 5, 2014I made a method which takes values from a data set and finds out which one is the highest value. When it finds the highest value, it returns the country which is associated with the value. Here's the data set.
"Country""Total CO2 2005 (million tonnes)""Road CO2 (million tonnes)""Road CO2 per person (tonnes)""Cars per 1000 people"
10
USA5951.131530.35.16777
UK2573.4119.681.99470
Italy476.08116.862592
Germany841.78150.211.82550
Canada553.02123.423.82562
France414.03128.132.04477
Russia1575.44114.690.8178
Japan1254.47224.241.76447
China5100.6228.020.317
India1147.4691.060.18
So if the number was 5951.13 then the program would return USA. How do I do that? I've already started on trying to get this code to work but it doesn't seem to compiler so what's wrong with it?
public static CO2Data highest (CO2Data [] arr2){
Scanner sc = new Scanner(System.in);
CO2Data highestindex = arr2[0];
CO2Data currentcountry = arr2[0].getCountry(sc.nextLine());
[Code] ....
Also the array is a CO2Data array which is part of the following class:
public class CO2Data { //The CO2Data class will be called in other methods
private String country; //A private variable will prevent other users from accessing and changing these variables.
private double totalCO2;
private double roadCO2;
private double CO2PerPerson;
private int carsPerPerson;
public CO2Data() {
country = "";//this sets the initial values for the different variables

Why Program Does Not Display Anything When Choices Are Inputted
Feb 28, 2014I am experimenting with messages in JOptionPane and I was wondering why this program does not display anything when the choices are inputted.
*note: I tried putting "JOptionPane.showMessageDialog(null, "This is an information message", "Information", JOptionPane.INFORMATION_MESSAGE);" after the "int i = 0;" and then the messages displayed.
Scanner scan = new Scanner(System.in);
int i = 0;
while (i != 6)
{
System.out.println("1. Information message");
System.out.println("2. Error message");
System.out.println("3. Question message");
System.out.println("4. Plain message");
System.out.println("5. Warning message");

Java Servlet :: What Determines Where Jar Files Get Placed In WAR
Apr 6, 2013Using Eclipse I have imported a WAR with source. I have exported that project as a new war and it ran fine. I then added my own package and exported the war again. The jar file does not show up in /WEB-INF/lib folder. When I deploy the war on a tomcat server it barfs the following error:
Caused by: org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.sharpline.fields.form.fields.TextAreaFormType] for bean with name 'com.sharpline.fields.form.fields.TextAreaFormType#53c37' defined in ServletContext resource [WEB-INF/activiti-standalone-context.xml]; nested exception is java.lang.ClassNotFoundException:

It looks to me like my class (jar) is missing in the final war. How do I resolve this?
For Loop With Parameter N That Determines Number Of Terms
Feb 10, 2014a. Write a code that is written inside a body of a method named average that takes two parameters: N that determines number of terms you should calculate the average of and lowBound that is the beginning term of the geometric sequence. if lowBound is 4 and N is 3, then the average of 4, 8, 16 is calculated and returned.
My code runs fine if I set the test as 16, but I can't figure out what I could do to N to have it determine the number of terms. This is what I have so far...
public class AvgIt {
public static void main (String[]args) {
double result = average(4, 3);
System.out.println("Average is " + result);

Encryption / Decryption - How To Separate Digits To Make Numbers Encrypted
Nov 4, 2014I've written most of the code (along with another classmate) to get this to work, but I can't seem to return the encrypted value. I'm also trying to figure out how to separate the digits (or if I'm supposed to) to make the numbers encrypted. The main kicker is that we have to be using methods to return the final values. Everything compiles, (It compiles, but no results really.)
A company wants to transmit data over the telephone, but they are concerned that their phones may be tapped. All of their data is transmitted as four-digit integers. They have asked you to write a program that will encrypt their data so that it may be transmitted more securely. Your program should read a four-digit integer number and encrypt it as follows: Replace each digit by the remainder after (the sum of that digit plus 7) is divided by 10. Then, swap the first digit with the third, and swap the second digit with the fourth. Then print the encrypted integer. Do the encryption in a method and send the encrypted number back to main.
Here are the method headers: public static int encrypt(int num) // Takes num as a parameter and returns the encrypted value public static int getnum() // gets one number from the user Example: If the user enters 1234 they should see: 0189
import java.util.Scanner; //Needed for Scanner class
public class LNFI_LNFI_program2
{
public static void main(String[] args)
{
getnum(); //Calls for getnum() method

How To Make A Program Run Multiple Times
May 18, 2014I have made a basic math game that asks you questions and tells you if you have answered them correctly or incorrectly. The game runs great! The thing is that it asks you a question one time and after you answer you have to run the program again. I want to get the program to ask ten questions. After that I want to figure out a scoring system for it but the first step is to get it to ask my ten questions. Here is my code.

Take Grades Program And Make A Class
Jul 17, 2014where to create the array of chars that hold the letter grade. I am assuming that would be in the main with the other arrays. Passing it into an object creating a method in the record.java. Then displaying it in my main.
Take the Grades program and make a class. An object that hold 5 student names, an array of 5 chars that hold the letter grades, 5 arrays of four doubles each to hold the set of test scores. The class should have methods that return a specific student's name, average test score and a letter grade based on the average. Demonstrate the class in a program that allows the user to enter each student's name and their 4 tests scores. It should then display each student's average and letter grade.This is my main program:
import java.util.Scanner;
public class GradeBook{
public static void main(String[] args){
Scanner input = new Scanner(System.in);
Record[] students = {new Record(), new Record(), new Record(), new Record(), new Record()};
