Ability To Search A Binary Search Tree And Return The Number Of Probes
Sep 1, 2014I'm trying to build a method that can search a binary search tree for a specific target and then return the number of probes it took to get there. It seems to me that the best way to do this would be a recursive search method and a counter that tracks the number of calls. But I'm struggling with how to implement this. Here's the code I have so far. what works/doesn't work with the method.
// Method to search the tree for a specific name and
// return the number of probes

MD5 Function Call
Jan 23, 2014my 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+"");

Mod Function With Multiples?
Jan 29, 2014where 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?
Calling A Function In JPA 2.1
Jul 16, 2014Using 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.

Function Calling In A Program?
Feb 12, 2015I 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.

Displaying Two Document From One If Function
Oct 15, 2014So 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' />

Simple Function That Returns Array
Jun 1, 2014Basically, it's to write a method that takes in, and then returns another array, whose first element is the average of the first two numbers, last element is the average of the last two, and then everything else is just the average of that index, the one before, and the one after. {1, 2, 4, 8} would return {1.5, 2.33333, 4.66666, 6}.I'm currently getting everything fine, except am not getting the last number (i.e. '6').
public class Arrays {
public static void main(String [] args){
double [] a1 = {1, 2, 4, 8};
for (int i = 0; i < a1.length; i++)
System.out.println(a1[i]);
