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:

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 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>
But I don't get any response ..... no error message NOTHING

I have understood my programming class up to this point and now I have been given a lab that I can't figure out for the life of me. Here what I have to do: Write a program that will call a method (called f) to calculate the following function" f(x)=(x^2)-16...this is what the output should be:
x f(x)
1 -15
2 -12
3 -7
4 0
5 9
6 20
7 33
8 48
9 65
10 84
I guess it also has to print this output in a table even though my professor never mentioned it. Usually
public class Lab12 {
public static int f(int x)
{
return x*x-16;

Write a function that will add the contents of a String array.
1. This time the input array to your function will be an array of Strings.
2. Your function body will be similar except you'll have to convert each String to a double number.

String aryVals[];
double result;

Working on my java skills. The is Delimiter function is suppose to return true if there is a delimiter in the string and false otherwise. The main is suppose to call this function and count the number of words in the string:
Here is what I came up with:
import java.util.*;
public class NumberOfWordsInString {
public static void main (String[] args){
Scanner in= new Scanner (System.in);
String s;
[Code] ....
Somehow my method isn't being successfully called by my main and the following error msg was received:
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
length cannot be resolved or is not a field
The method isDelimiter(char) in the type NumberOfWordsInString is not applicable for the arguments (char[])
at javaimprovements.NumberOfWordsInString.main(Number OfWordsInString.java:10)
line 10:
char ch [] = new char [s.length];
and the main doesn't call the isDelimiter function
I am encountering a problem while running this small piece of code.

String myWords[]="My.Home.Is.Being.Painted".split(".");
for(int i=0;i<myWords.length;i++)
System.out.println(myWords[i]+" ");
}
}
The problem is: it does not run at all. No error message is displayed. It just returns to the command prompt when i run it. Where am i wrong?
The following code is located in my main class called InjectionFix. I have another class where I need to call or initiate the string in the code below. How can I achieve this.

What it is supposed to do is decide whether a ceiling fan is on or off, and describe it (color, area, speed). This is all user input (even pi) so it should decide whether to turn it on or off but for some reason skips over my if/else if statements all together.
I've tried changing it around a bit, looking up what my problem may be but this problem remains the same. my code:
import java.util.Scanner;
public class CeilingFan
{
final int slow = 1;
final int medium = 2;
final int fast = 3;
private int speed;
boolean on = false;
private double radius = 5;
private double pi = 3.1415;
String color = "blue";

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.
View Replies View Relatedwhere 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?
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.
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:
ASSERT_NO_THROW({

How will it look in Java?

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' />
