where I have to write a Java program that asks for user input regarding a book and provides information based on that input like the number of pages required, number of words on the final page and if the final page is more than half full, etc. We are told that each page should have 250 words maximum to use for our calculations. The problem I am having here is that when the total number of words is a multiple of 250 the output tells me that there are 0 words on the last page when in fact there are 250. I've tried messing around with mod functions in this format ((x+a)%250)+y which is what the professor told us to use instead of creating an if-statement for this case but I haven't been able to crack it. I don't think I fully understand how the mod function cycle could work for this case.
import javax.swing.JOptionPane;
public class CorreiaFranciscaA1Q1 {
public static void main(String[] args) {
String ManuscriptTitle =
JOptionPane.showInputDialog ("Please enter a book title.");
String AuthorName =
JOptionPane.showInputDialog ("Please enter the author name.");
String TotalWords =
JOptionPane.showInputDialog ("Please enter the number of words.");
[code]....
Above if totalWords is a multiple of 250 like 17500 then wordsFinalPage will give us 0 and I need it to give 250. How can I do that without using an if statement but instead using a mod function?
I'm trying to get this program to work but it keeps giving me all multiples, including ones over 1000 when I want it to not go over 1000. What am I doing wrong?
* A program that will prompt the user to enter a number and * then print out all the multiples of that number that are less than 1000. * */ import java.io.*; import java.util.Scanner; import java.text.*;
What ever positive value which has multiples keeps on displaying " No multiples ........ where found, and the answer.how can i fix the colored part ?
import java.util.Scanner; public class Problem4 { public static void main(String[] args) { Scanner input=new Scanner(System.in); int n; boolean x=true; System.out.print("Enter an integer n: "); n=input.nextInt();
I just started learning Java, I was asked to write a simple program that prints a message if it encounters the number 7 or its multiple.
This should be achievable using simple loops and simple operations...
Here is my attempt:
Java Code:
Scanner scan = new Scanner(System.in); int i, j, temp; i = scan.nextInt(); // Awaiting user input j = scan.nextInt(); // Awaiting user input if (i > j){ // i = 10 j = 0 temp = i; // temp = 10
[Code]...
Now it works fine for numbers that are less than 70...
I am not sure what to do in case if for example 'i' and 'j' are very big numbers
I mean, I need it to detect the 7s even if it in the thousands place, actually - no matter how big is the number... So far I only made it to work for numbers that are less than 70...
the prime numbers from 1 to 2500 can be obtained as follows. From a list of the numbers of 1 to 2500,cross out al multiples of 2 (but not 2 itself). Then, find the next number (n, say) that is not crossed out and cross out all multiples of n (but not including n).
Repeat this last step provided that n has not exceeded 50 (the square root of 2500). The numbers remaining in the list (except 1) are prime. Write a program which uses this method to print all primes from 1 to 2500. Store your output in a file called primes.out.
my first assignment is to convert a md5 string to password of the user, the MD5 function is available, i just need to call it and print the result. Here is my code. I can't call the md5 because of the String[] and String is different in main and md5 function,modify the code so it can run properly, also the input has to be entered from command line.
import java.security.*; public class PasswordCracker { public static void main (String[] args){ String password; md5(args) System.out.printf(""+password+"");
I'm trying to create a booklist in java using swings but I'm facing a problem. I don't know how to add a search function to my list. I need a search box with the book names.
Using JPA 2.1, I have been trying without luck to call a function that returns a REF CURSOR containing RECORD TYPES. Is there a way of doing this?
One Example of trying:
Query query = em.createNativeQuery("select my_package.my_function from dual"); Object a = query.getSingleResult();
I have also tried to use the StoredProcedureQuery though this does not look like it can return the functions value.

I just wanted to ask that when we invoke a function by passing certain arguments in it ,so for instance I have certain variables like a,b and c with some values assigned to them,so when I invoke a function like func(a*b , 8, c+a) where the function func accepts parameters like func(int x,int y,int z) ,so is there any order of evaluation of expressions defined like the value of c+d would be evaluated first and then assigned to variable z ,because in C we have sequence points and since comma when acting like a separator is not a sequence point so any of the expression can be executed first ,so basically is there any sequence in which the function arguments are assigned to the parameters of the function or any relation with the stack implementation.
Even in C ,the printf starts executing its expressions from right to left so basically in why does it happen there when comma is a separator in a function argument.

I have 2 JButtons on my JFrame and i would like to add a function to it when i click on them.
I would like the JButton calculator allow me to open another JFrame if thats possible and i would like the JButton Exit allow me to exit the current Frame.

Is it possible to create a JInternalFrame class with additional public functions that can be called from the desktop? Here is some snippets of the code. This is the Internal Frame with the public functions added after the constructor.
public class Search_Ifr extends javax.swing.JInternalFrame { /** * Creates new form Search_Ifr */ public Search_Ifr() { initComponents();
[code].....
The line " ifrSearch.setTabPaneIndex("tabCust");" is throwing a compile error that the method is not found.
I am using AXIS2 tomcat6 and jre1.6.0_07 and I created java project using net beans. but when I execute java2wsdl I am getting the following. Can you solve my problem? Also I would like to know what is the function of java2wsdl and its parameters?T
I am trying to code a program which pops up a file chooser window or dialog box to select a file first, if the user clicks 'cancel' or closes the window then the parent JFrame would not show up.
Java Code:
import java.util.logging.Level; import java.util.logging.Logger; import javax.swing.JFileChooser; import javax.swing.UnsupportedLookAndFeelException; public final class base extends javax.swing.JFrame {
[Code] .....
The problem is that the JFrame shows up even if I click cancel in the file chooser. I am using Netbeans.
