Mod Function With Multiples?
Jan 29, 2014
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.

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...
Example for output with i = 15, and j = 25:
Java Code:
15
16
!!!
18
19
20
!!!
22
23
24
25 mh_sh_highlight_all('java');
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.

I would use the return value of a function how parameter of other function..In java is:
// the call produce "YES"
SecondClassController.funcSecondClass(FirstClassController.funcFirstClass());
In my web page I need to do something like this:
[...]
<h:outputText value="#{secondClassController.funcSecondClass(#{firstClassController.funcFirstClass()})}" />
[...]
obtain:
javax.servlet.ServletException JBWEB006007: Failed to parse the expression
@Named
@SessionScoped
public class FirstClassController implements Serializable{
[...]

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+"");

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.
Produced
org.springframework.orm.jpa.JpaSystemException: No Dialect mapping for JDBC type: -10;
nested exception is org.hibernate.MappingException: No Dialect mapping for JDBC type: -10

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.

E.g:
onblurr="check(this, '<%=company.getId()%>' );return false;"
doing this, function check(field, inputVal) {
alert("companyId:" + inputVal);
}
Gave me the alerted value as :
companyId:<%=company.getId()%>
instead, if the company.getId() --> 30
When I do like this, how to get the value 30 inside the function? i want companyId:30

I want to test that a function has no any exceptions.In C++ and Google Test Framework (GTest) it will look like this:

Here start is the variable whose value will vary after every time i visit this function.So how would i be able to use above query.
P.S. i was using scriplet before and i was able to deal these issues with scriplet easily.

So I have this
function checkvalue (val) {
if(val==='replaced')
document.getElementById('check1h').style.display='block';
else if (val==='checked')
document.getElementById('check1h').style.display='none';
else
document.getElementById('check1h').style.display='none';
}
Which works fine... But if I try and add another document under the if VAL === replaced then nothing works and neither of the boxes appear.
function checkvalue (val) {
if(val==='replaced')
document.getElementById('check1h').style.display='block';
document.getElementById('check1n').style.display='block';
else if (val==='checked')
document.getElementById('check1h').style.display='none';
else
document.getElementById('check1h').style.display='none';
}
Is this not possible?
Also, Both of my input type are set up like this...
<input type='text' style='display:none' name='check1n' id='check1n' placeholder='Name of Part' />
<br>
<input type='text' style='display:none' name ='check1h' id='check1h' placeholder='Part Number' />

bool estaEncendido(char byte,int pos)

//byte = byte>>(pos+1);
int mask=1;
int result =1;
for(pos=0; pos<8; pos++, mask <<=1)

I an using a pop out java script and in the notes it says
if later on you want to open / close a specific item you could do it like so:
ExpandingMenu.openItem(3); // toggles item 3 (zero-based indexing)
*/
How to call the function from a button click. I have some button already on my page like so
<li><a href="#">Menu3</a></li>
And from what I have read I should be able to do this:
<li><a href="#" onclick="ExpandingMenu.openItem(3)">Menu3</a></li>
